8. The Human Form and Its Co-ordination of Forces
It will be my task to-day to blend into a sort of picture, though naturally only a sketchy one, our reflections of the last few days regarding “occult physiology,” in which the endeavour has been made to present (though in part likewise only sketchily) much that pertains to the processes of the human organisation. Through this picture it will be possible for us to have a vision of the quickening life which weaves and works throughout the human organisation. Here again our best procedure will be to start from the most common and everyday side, the reciprocal relationship between the human organisation and the outer world, our earth, in the process of taking in nutritive substances.
It is these substances, as we know, after they have been taken in and have passed through various stages of change, that are conveyed through the most diverse actions of the organs to the separate members of the human organisation, to all the individual systems constituting the physical being of man. Indeed it requires no special effort to see that, fundamentally considered, what the human organism succeeds in doing with the nutritive substances is what really makes the human being into the physical man as he stands before us in the physical world. To be sure, there is a certain difficulty in taking such a view. But anyone who is serious about the principles that have here been applied in our reflections regarding the human being, must say to himself that everything else to be considered in connection with the human organisation, apart from this impressing of nutritive substances into the organism, is, fundamentally viewed, something super-sensible, invisible, the actions of hidden force. If you banish from your mind for a moment everything by way of nutritive substances which fills out the human organism, you retain as a physical organisation even less than a mere physical sack, if I may be permitted this trivial expression; indeed, you retain nothing whatever of a physical character. For even what exists in the form of skin and outer covering exists solely by reason of the fact that nutritive substances have been driven to particular areas of action of super-sensible forces. Cancel then from your reckoning the nutritive substances and what is produced out of them, and you have to conceive the human organism as a system of super-sensible forces working behind it in such a way that these same nutritive substances may be conveyed in all directions.
If you hold to this thought you will see that one thing must be presupposed before any nutritive substance whatever, even the tiniest particle, is taken in; for these substances could not be taken in from the outer world in just any chance form and conveyed into just any being, in order that those processes should occur which do occur in the human organism. It must be, then, that this human organism confronts the very first nutritive substances taken in with an inner co-ordination of forces coming from the spiritual worlds; the organism must really be “man,” as such, in this inner co-ordination of forces. In all occultism, this which first confronts the purely physical matter that is to fill out the human being and which must, therefore, always be conceived supersensibly) is called, in the most comprehensive sense of the expression, “the human form.” If, therefore, you descend to the nethermost boundary of the human organisation, you have to conceive the primary super-sensible human form which, as a force-system born out of the super-sensible worlds, is destined, not like a sack or a physical bag but as something superphysical, super-sensible, to take in what alone renders possible the physical-sensible manifestation of the human being. Only by reason of the fact that this super-sensible form incorporates the nutritive matter does the human organism become a physical-sensible organism, something that our eyes can behold and our hands can grasp. That which thus confronts the external nutritive substances is called “form” in accordance with the law that is operative throughout the whole of nature, an identical law termed the “principle of form.” Even though you descend to the crystal, you find that the substances which enter into it, if they are to become what is manifest as the crystal, must be seized as it were by form-principles, which in this case are the principles of crystallisation. Take for example kitchen salt or sodium chloride: here you have, according to our present-day physics, the physical substances chlorine and sodium, a gas and a mineral. You will readily see that these two substances, prior to their entrance into the entity which lays hold upon them in such a way that, in their chemical union, they appear crystallised into a cube, have nothing in them that can indicate to us such a form-principle. Before they enter into this form-principle they possess nothing in common, but they are seized upon and yoked together by this form-principle and there is then produced this physical body, kitchen salt. They presuppose this, we may say. And so everything which enters into the human organism as nutritive substance presupposes the nethermost of super-sensible being, the super-sensible form.
Now, when the nutritive substances enter into that sphere which, by means of this form-principle, is externally bounded as the human being, they are first taken in by the alimentary canal. When they are thus taken in, from the moment they enter the mouth, one might say, they at once undergo the very first change, indeed the alimentary canal itself causes a metamorphosis. This could not be produced if there were not present as an integral part of the human organism, something which would so metamorphose these nutritive substances—entirely neutral in relation to each other when first taken in and possessing no living inter-relationship—that they are evoked into life. We must think of the metamorphosis of the nutritive substances in their passage through the human alimentary canal as similar to that of plants when they take their nutritive substances from the soil, although, of course, the process is quite different in the human being because it takes place at a different stage. We must picture to ourselves a nutritional stream, taken in by the life-process, or, as we say in occultism, by the ether-body. The moment the nutritive substances enter the human organism they are worked over by the ether-body: that is, the ether-body first provides for their metamorphosis, for their being made a component part of the inner vital activities of the organism. We thus have to look upon this nearest super-sensible member of the human being, the ether-body, as the stimulator of the first process of metamorphosis in the nutritive substances. After these substances are sufficiently metamorphosed to have been taken up into the life-process, we must understand clearly that they are still further worked over—in just that sense, and in the same way, which we have described in the preceding lectures. They must be still further adapted to the human organism, be so worked over that they are able little by little to serve those organs which are the manifestation of the higher super-sensible principles, the astral body and the ego. In short, the work of the higher processes clearly is to send their own peculiar kind of inner vital activity down as far as these metamorphosed nutritive substances as they are when they have come through the oesophagus, the stomach, the intestines, etc. At this point the nutritional stream, in so far as it has been metamorphosed by the alimentary canal alone, is confronted by those seven inner organs already known to us which represent, as we say, the inner cosmic system of man. To sum up, the nutritive substances are taken in, at once metamorphosed in the most diverse ways in the alimentary canal, and then confronted by the liver, kidneys, gall-bladder, spleen, heart, lungs, etc.
If we further understand that these organs are designed through their corresponding force-systems to work further over the nutritive substances, we may say with regard to the meaning of this metamorphosis that, if the nutritional stream were worked over only to the extent to which this occurs in the alimentary canal, man would have to lead a plant existence; for he would not have attained to the formation of such organs in the physical world as could become the instruments of his higher capacities. Thus the seven organs further metamorphose the nutritional stream, and what they do is prevented by the sympathetic nervous system from entering human consciousness. We have consequently, in the sympathetic nervous system and the seven organs, that which confronts the nutritional stream. We have now gone far in penetrating from the outer into the inner side of the human organism. For everything that goes on within there, as the mutual concern of the seven organs, is something that could never go on anywhere else in our terrestrial world; and it can take place here only because this inner world is shut off from the outer world, and because its activity is provided for beforehand by the alimentary canal. Thus in our reflections we are already in the inner human organism.
And here we must take note of something peculiar. Now that we are within this organism we find that it must again inwardly organise and differentiate itself. For the performance of its manifold undertakings it must work as a multiplicity of organs; and it is precisely for these inner functions that a very great deal is needed. Whatever more is now to be attained can be attained only in the following manner; and we shall understand this if we first imagine how it would be if there were only this metamorphosis of the nutritional stream by means of the seven organs, the inner cosmic system, and imagine also that this process were concealed from our consciousness by the sympathetic nervous system. That would mean that man would never be able to unfold into a being possessed of consciousness; he would never have even the dimmest form of the consciousness which he now possesses. For everything occurring there is withheld from him. A connection must be established between this system of organs, built into him, as it were, from without, and everything else in the interior of the human organism. This connection is actually established through the fact that everything provided by the nutritive process as a whole causes the entire form of the organism to be interwoven with what we call tissue, in the broadest sense of the term. Tissue, one of the very simplest forms of organisation, is woven through all the separate members of the human entity. And out of this tissue the most diverse organs form themselves. Certain kinds of tissue, for instance, change themselves in such a way that when they have added to their composition other special kinds of cells they are transformed into muscles. Then again, other kinds change themselves by hardening and, through the appropriation of suitable substances, by depositing bone-cells. Thus, in the single organs which form themselves so as together to fill out the form of the human organism as a whole, we must think of something as underlying this organism: in other words, we must think of tissues woven throughout the body, and active everywhere, bringing forth out of themselves the individual organs.
But this tissue, no matter how much it might grow, and no matter how many individual organs it might put forth out of itself, would still constitute basically nothing more than something plant-like; for the essential nature of the plant lies in the fact that the plant-entity grows, that it produces organs out of itself and so on. Since however in the case of man we are to go beyond the plant nature, an entirely new element must present itself by means of which man becomes capable of adding to what exists in plant-life, that which elevates him above it. That is, man must add consciousness, the simplest form at first, that dim consciousness by which he is aware of his own inner life. So long as a living being does not consciously share in its own inner life, is not in position to mirror its own inner life and thus share it consciously, we cannot say that it has risen above the plant nature. Only through this fact that it does not merely have “life” in itself, but mirrors the flow of its inner life and raises it to conscious life, does any being rise above the plant-like state. It is at first, then, an inner experience, an experience of the inner life-processes.
How does conscious inner life come about?
We have already forecast a conception of this. In the earlier lectures we have shown that conscious inner life comes about through the processes of secretion.1See footnote on p. 79. For this reason we shall have to look for the basis of inner experience, of that dim experience of consciousness which permeates the inner life-processes, in the processes of secretion. We shall have to presume that everywhere, out of tissues, out of all that underlies the human organisation, processes of secretion are taking place. And these secretory processes again do manifest themselves when we observe the human body externally and see how substances from all parts of the tissue and the organs are continually being taken up by what we call the lymph vessels, which permeate the whole organism as another kind of system parallel to that of the blood. From all regions of the human organism those secretions which mediate that dim inner experience enter this system. Thus we might in abstract thought banish from our minds for the moment the whole system of the blood, in which case indeed we should conceive the tissue as though it possessed no blood-like character. This is quite conceivable, and the fluids in the lower organisms do actually have such an appearance. We should thus have to imagine our blood-process as one higher than that which takes place when secretions from every region of the organism enter into the lymph-channels which, we know, accompany the blood-channels which join them later. In these secretions the human being dimly feels, as it were, his animal existence in the physical body, dimly mirrors his organisation. And, just as everything is held back by the sympathetic nervous system which comes to life through the digestive and nutritional process as far as the seven organs, just so through the reflection of the activity of the sympathetic nervous system, through the association and reciprocal action between this system and the lymph-channels, there is formed for the present-day human being a dim consciousness which is outshone by the clear day-consciousness of the ego. This dim consciousness is, as it were, the obverse side of that consciousness which utilises the sympathetic nervous system as its instrument. It is outshone, as a powerful light outshines a feeble light, by all that lives in our souls under the influence of the ego.
Now let us suppose for a moment that we had evolved the human organisation only to this point, to the formation of the bodily tissues and the first organs that must be formed in order to render possible all these processes; for you can see that certain muscles have to be incorporated to enable such processes to take place as, for example, the secretions into the lymph-channel. A man thus organised would be able to maintain a dim consciousness of his inner life in the physical world, mediated to him by means of his organism; but he would not be able to attain to that ego-consciousness which can be present only when man does not merely have an inner experience of himself as a being, but also opens himself to the external world. It is this opening again outward, so to speak, to which we must here call attention.
We have already spoken indeed of this reopening outward. We have shown how the human being opens himself again to the outside world in his breathing and so forth, in order to enter into direct contact with the physical world. We may now go even further, since we have seen how hard it is to apply ordinary concepts to these things, and say that, so long as we confine ourselves to the inner man, we can go only as far as the alimentary canal; for, inasmuch as the extensions of the seven organs reach into the alimentary canal and show themselves there (the liver empties through the gall-bladder into the duodenum) and show their influence in the digestion, we at once disclose, through the impact of this inner cosmic system on the alimentary canal, something which amounts to the reopening of ourselves to the outer world. Thus it is really an opening outward when the human being declares himself ready to receive nutritive substances from without; and hence we need reckon the inner man only as far as the boundary of the alimentary canal. Then we have also another opening outward through the breathing, on the one hand, and on the other hand through the higher organs which serve the functions of the soul.
Thus we see how man, in so far as he has the stage of the dimly conscious inner life as something basic in him, so to speak, reopens himself in order to form a connection with the external world. Only in this way can man become an ego-being. For it is not merely in the process of sensing the resistance in his own inner world, in his processes of secretion, but through the fact that he opens his inner world and senses the resistance of the outer world, that he is able to evolve his ego-consciousness. Thus it is really wholly in the fact that man reopens himself outward that we find the basis for his physical egohood. At the same time, however, he must also possess the capacity to develop the organ of this egohood in the most manifold ways. And we have seen how the organ for the ego here fits itself into the circulatory course of the blood, which in fact passes through all these inner organs, in order to serve throughout the whole human organisation as an instrument for the egohood. Just as the egohood permeates soul and spirit in the whole man, so does the circulatory course of the blood physically permeate his entire organisation. And this organisation thereby evolves these two sides, so to speak: the inner human being in the seven organs, the sympathetic nervous system, the system of tissues, and predominantly in the digestive apparatus, etc.; and the other side that again opens outward, coming into connection with the outer world, a real “circulation” in the highest sense of the word.
We must now give still further attention to the individual phases of this circulation. And what concerns us here, first of all, is to follow once more the nutritional process, the taking in of nutritive substances which become a living stream in the human organism through the fact that they are taken up by the ether-body, or, rather, are grasped by the force of the ether-body. The inner cosmic system, consisting of the seven organs, then meets these substances; and it does this because, as we have seen, the human being would otherwise not rise above a plant-existence. The higher stage of man's being requires that these seven organs should go out to meet the digestive process. So that it really is what comes to life in the astral nature of man that works upon the nutritional stream: this stream comes from without, and that which constitutes the inner nature of man goes forth to meet and work upon it. First of all the ether-body meets the nutritional stream, and metamorphoses its substances all along the course of the digestive system; then the astral system goes forth to meet them, metamorphoses them still further, and makes them so much a part of the inner world that they more and more become inner vital activities. And now, since everything in the human organism constitutes a co-operative unity, the entire nutritional stream must in addition be taken hold of by the forces of the ego, by the blood itself. That is, the instrument of the ego must extend its activity down to where the nutritional stream is taken up. Does the blood do this? Can we verify that which occult perception compels us to affirm?
Yes, we can; for the blood is actually driven down into the organs of nutrition, just as it is into all other organs. In this nutritional organisation, as elsewhere, it goes through the entire process whereby it is capable of being the instrument of man's ego in the physical world. We know that the blood, as the instrument of the ego, passes through the transition from red blood to blue, so that here, too, it meets with resistance. Thus the ego, by means of its instrument, reaches down even to the nutritive processes, since this transformed blood, in order to be the expression of the ego, works upon almost the first beginnings of the nutritive process. This occurs through the fact that the system of veins discharges into the liver, and that out of this modified blood the gall is prepared, which then comes into direct contact with the nutritional system.
We thus have a wonderful union of the two extremes of the human organisation. The nutritional stream, on the one hand, is taken into the digestive tract and this represents the external matter which enters our physical organisation. The ego, on the other hand, together with its instrument the blood, constitutes the noblest endowment which man possesses in the terrestrial world. It establishes a direct connection with the nutritional stream in that it comes to the very end of the blood-process, and there, at the end of the blood-process, in turn brings about the preparation of something which, we may say, directly confronts the nutritional stream. In other words, the gall is prepared by the instrument of the ego, the blood, through the roundabout way of the liver; and in the gall the ego opposes the nutritional stream. For at this point the activity of the blood has come to an end and, before acting upon the nutritional stream, it is able to prepare the gall.
Here we see the one working downward, as it were, into the other. And whoever has the will to do so can see in this very fact something that leads in a wonderful way into many, many mysteries of the human organisation. He can follow these processes still further, including abnormal processes, which take their course, for example, in a reverse discharge, a congesting and reverse discharging of the gall into the blood. He might thus quite easily form an opinion about “jaundice,” for example, its cause and effect; but it would take us too far afield if we were also to discuss such things as this to-day.
Thus we see how the seven organs reach as an actual fact down into the action of the ether-body and have taken into themselves, from above, the influence of the ego. In the gall we have the ego setting itself in direct opposition to the nutritional stream. If, now, the gall is to meet this nutritional stream, which has already become a living stream in the alimentary canal, it must itself likewise meet it as a living substance; otherwise a truly continuous process could not come about. The gall must be enabled, as a living substance, to meet the nutritional stream. This occurs through the fact that the very organ in which this gall is formed is one of the seven organs of the inner cosmic system, which vitalise the inner life of man in order that it may as inner life meet the outer life. We pass from the gall-bladder back into the liver itself, and the liver in turn we find connected with the spleen.
When we more closely observe the liver, the gallbladder, the spleen (this follows quite naturally out of our previous reflections, for the spleen has been fairly accurately considered in this connection and used as an example) we must affirm that it is these organs that directly confront the nutritional stream and so metamorphose it that it is capable of advancing to the higher stages of the human organisation, and also of caring for those organs which open themselves to the external world. Those which open outward are the heart (through the lungs) and, of course, the alimentary canal itself; but, most of all, the organs in the head which serve as the organs of the senses.
We must now understand clearly that all inner perception, all inner experience, must have something to do with processes of excretion. It is for this reason that we have given special consideration also to these excretory processes. Liver, gall-bladder, and spleen have nothing to do directly with processes of excretion; the fact that they secrete their own nutritive substances is a different matter; but they do not excrete anything with respect to the organisation as a whole. They signify the ascending life, which turns away from a mere being alive and directs itself to the organisation of consciousness. Since, however, the heart is added as a fourth member to this organisation, and since the heart opens itself to the outer world, man attains through this opening outward his ego-consciousness. Yet he would not be in a position to experience this ego otherwise than merely as something which faces the outer world. He would not be able to bring this outward-looking ego into relationship with what he experiences by means of his inner organs as a dim corporeal life within him. He must add to the secretional processes of the inner organisation still another process which makes possible for him an experiencing of his inner being by that ego which has its instrument in the blood. At first man realises his inner life only in a dim consciousness and we have seen how this manifests itself in the organisation through the fact that the processes of excretion are taken up by the lymph-ducts from the liver, the gall-bladder, and the spleen. In the same way something must be excreted from the blood, if man is to rise to a really conscious ego. And it is in this excretion that he becomes aware that, as an inner entity, he confronts the outer world. If man did not have these inner excretional processes he would, in his realisation of inner life, so face the outer world that he would inwardly lose himself; or he would at most realise dim inner processes but would not know what is outside him, he would not know that what is inhaling the air and taking in nutritive substances is the same as the being which is working in him. It is possible for him to know this through the fact that he excretes the modified blood through the lungs, in the form of carbonic acid gas; and that, through the kidneys, he excretes the metamorphosed substances which must be removed from the blood in order that he may have an inner perception of his own entity.
Thus we find our assertion justified, that the organs which represent an ascending process, the liver, the gallbladder, the spleen, as well as those representing in a certain sense a descending process, the lungs and the kidneys (although the lungs, in that they open themselves to the outer world, are at the same time the means of an ascending process; the individual organs are constantly in living reciprocal relationship, and we must not establish any hard and fast classification) we see how all these seven members of the inner human cosmic system are bound up with man's realisation of inner life, and with his opening of himself to the outer world. These seven members completely metamorphose, on the one hand, the vital activities peculiar to the nutritive substances into inner vital activities; and with these metamorphosed substances they provide for the human organism. They make it possible for man to reopen himself to the outer world. But, in addition to this, they bring it about that what he evolves as an excessively strong inner vital activity, which would not harmonise with the vital activity that penetrates into him from without, is brought into balance with this outer vital activity by being thrown off through the excretional processes of the lungs and the kidneys. So that we have before us the complete and regular control of the inner vital activities in this inner cosmic system of man. And in fact this entire relationship manifests itself in such a way that the best picture occultism can give us is to conceive the heart standing as the sun, at the centre, and caring for the three bodies of the inner cosmic system which signify the upward rising and upward bearing process. In the same way in which the sun is related to Saturn, Jupiter, and Mars in the planetary system, so is the inner sun, the heart, related to Saturn, spleen; Jupiter, liver; and gall-bladder, Mars, in the human organism. I should have to speak, not for weeks but for months, if I were to explain all the reasons why the relationship of the sun to the outer planets of our planetary system may really be declared to be parallel, for an exact and intimate occult observation, to the relationship which the heart sustains in the human organism to the inner cosmic system, i.e., to the liver, the gall-bladder, and the spleen. For it is an absolute fact that the relationship existing in the outer cosmos has been so adopted into the organism that what goes on in the great world or macrocosm, in our solar system, is mirrored in the reciprocal action among these organs. And those processes which go on between the sun and the inner planets, working inwards from the sun to our earth, are again reflected in the relationship of the heart-sun to the lungs as Mercury, and to the kidneys as Venus. Thus we have in this inner human cosmic system something which mirrors the external cosmic system.
We have already indicated, how, when we delve clairvoyantly into our own inner organism we can perceive this interior of ours; and that we then cease to perceive our inner organs in the way they manifest themselves merely to the external observation of the physical eye. We then go beyond the fantastic picture of our organs conceived by external anatomy, for we rise to the observation of the real form of these organs when we bear in mind that they are systems of forces. External anatomy cannot possibly establish what these organs really are, for it sees only the nutritive matter stuffed into them. And no one can doubt, when he goes more deeply into the matter, that external anatomy sees only the stuffed-in nutritive substances. That which lies at the basis of these organs as force-systems can be seen only by clairvoyant observation. And what we see justifies our nomenclature, because we discover the outer cosmic system duplicated in our inner cosmic system.
We stated yesterday that the organism may develop too strong an inner vital activity. Each separate organ may develop too strong an inner vital activity. This is then manifested in the irregularity with which the organism acts. I indicated yesterday that when, by reason of this excessive inner vital activity, there appears in the inner organs a self-willed life of their own, it is important that something should be set in opposition which will subdue these inner vital activities. That is, when the inner organs transfer too vigorously the external vital activities of the nutritional substances, transform them too much, when they provide an inner product too strongly metamorphosed, we must then set in opposition to them from without something which will dam up, as it were, will subdue the inner vital activities.
How can this be brought about? By introducing into the organism something from the external environment which possesses a vital activity contrary to those of the organs and is capable of combating them. That is, we must endeavour to discover those external vital activities which correspond to the peculiar vital activities of these organs. To contemporary man, who sometimes comes upon such things in the mangled writings of the Middle Ages yet cannot look upon them as anything but a jumble of superstition, it sounds quite amazing when he hears that for thousands of years occult science has not only examined, profoundly and thoroughly, the correspondence between the vital activities of these organs of the inner organic system, and certain external substances possessing the opposite vital activities; but that also, through countless observations made with the clairvoyant eye, there has resulted the knowledge, for example, that when the inner “Jupiter” oversteps its limit it can be checked if confronted with that external vital activity manifest in the metallic substance tin. The inner vital activity of the gall-bladder, we combat by what is manifest in the metallic substance iron. And we ought not really to be surprised to learn that the gallbladder is the very organ to be combated by iron. For iron is that metal which we require particularly in our blood, and which therefore belongs to the instrument of the ego; and we have seen that in the gall-bladder we have the very organ which brings about the connection of the ego with the densest matter deposited in the human being through the digestive process. In the same way the spleen (Saturn) has its correlative in lead; the heart (Sun) in gold; Mercury has its own name: that is, the metal mercury (or quicksilver) corresponds with the lungs; and the metal copper corresponds with the kidneys.
Now, when we introduce into the organism such vital activities as exist in these metals, in order to combat the excessive vital activities of the inner organism, we must realise that everything in the organism is more or less interrelated with everything else; and indeed that the individual organ-systems were formed in a mutual parallelism one with the other. For it is not as if there first existed in a finished state what we have here merely sketched in our drawing, i.e., what we may call the headless man; but rather the brain and the spinal cord form themselves simultaneously with the other organs, so that the blood-process extending downward extends also upward. And, just as we have pointed out that there are these two circulatory courses of the blood, so we have similarly an upward action of the lymph-system toward the head, and have, therefore, a dim consciousness apportioned also to the upper parts of the organism. This is true because of the fact that what is incorporated above in the upper blood-stream corresponds in a certain way with what we have described as the incorporated lower blood-stream.

From this we now see that certain of these metals to be found on the earth have their respective kinship with the organs or members which we find embedded in the upper blood-organisation. That which, in the lungs for example, opens itself upward into the larynx, thus becoming an organ of the higher human organisation, and which otherwise presses down into the gall-bladder as dim life, acts correspondingly as a Mars- or iron-system in the larynx which contains the upper part of the lungs. These things are, of course, hard to differentiate; but I should like, nevertheless, to point out some of them. In the same way the upper part of our head containing the brain-formation corresponds, as regards its position in the upper course of the blood, to the position of Jupiter-liver (tin) in the lower course of the blood; so that we have here a correspondence between the fore part of the head, in the upper course of the blood, and tin, or Jupiter; and, in the same way, between the back of the head and lead, or Saturn. And so it is with the organs which may be looked upon as embedded in the upper cosmic system.
We have been able in this way to extend our reflections to that which is incorporated in the circulatory course of man's blood, as having a connection with this, but also as determining it as the organisation of the seven members of the inner cosmic system. And we have been able to take into consideration the connection with the external world as regards both the normal and the abnormal condition of life. In this correspondence between the metals and the inner organs we have a most interesting fact. And if all that which is contained in manifold form in the statements to be found in our books dealing with therapy is ever assembled and compared, not in chaotic manner but systematically, this picture that we have formed will one day, quite of itself, burst into view as a result of the external facts. We can always affirm, when we work creatively in the right way with the help of occult sources, that we can quietly bide our time, that the facts themselves will one day confirm all this for mankind!
When we introduce into the organism the substances of these principal metals—and they are all metals that pass over at a certain temperature into a sort of vapour in which there is active something resembling little smoke-like globules—the particular quality of the respective metals acts upon what is in these seven organs. And just as the metallic element acts upon these systems of organs, so anything in the nature of a salt acts upon the blood-system. Only, we must introduce the salty substance into the blood in such a way that it enters from outside, through the air, through air with a saline content, or through a salt bath; or again we can introduce from another direction, through the digestive process, what constitutes salt or builds up salt, so that we are in a position to bring about from two directions this process which results in the formation and depositing of salt.
When you recall what I explained yesterday as the physical effects of the inner processes of soul and spirit, you will understand that everything which meets the processes brought about by these metals as metals, processes which embed themselves in these systems, forming tiny globules, as it were, is what I designated yesterday as the physical effect of the feeling-processes.
Thus the dim feeling-processes and the higher feeling-processes are bound up with that which constitutes inner liquefying processes, on the one hand, when it develops the right inner vital activity, but which, on the other side, can be checked if something is introduced from outside, if the appropriate substances which have their external counter-activities embed themselves in these systems from outside.
When, by reason of excessive digestive activity occurring where the nutritional stream is seized by the ether-body, this body develops a too insistent inner vital activity of its own so that it contradicts that from without—when this process of a self-willed inner vital activity gets the upper hand, we can work in opposition to it through the process of introducing salt in so far as salt works as salt. In the case of an intensified inner vital activity of those very processes which go on where the external nutritional substances are seized upon by the ether-body, signifying too intense a taking up, a sucking up of salt out of everything, the process is combated through the external vital activity of salt.
Then we also have processes which occur outside us as processes of combustion or oxydation, when something or other combines with the oxygen in the air. When substances which readily combine with the oxygen in the air are taken into the organism, they radiate their inner activity most extensively throughout the inner organism. Whereas salts act only when introduced into the organism through the digestion or from without into the blood, and hence can get only a limited access to the inner organism; and whereas we can, with metals, work in as far as the inner cosmic system we have, in the external vital activities of the substances that readily unite with the oxygen of the air, something which radiates through the whole organism, even into the blood: something which is capable of radiating through all the systems of organs. We shall thus find it comprehensible that through such processes as develop too strong an inner vital activity in warmth, which is the outward manifestation of the development of the will, we find ourselves inwardly aroused, as it were, in our entire organism. Such is not the case if we direct our attention to those other processes which constitute the organic processes of thought. We feel there that the actions which, in yesterday's lecture, we connected with salt can take place only in certain organs. From this we see how complicated an apparatus the human organism is, and, at the same time, how complicated is its relation to the external world. Moreover, we see that we have now for the first time set the human organisation with its inner vital activities over against a mineral, inorganic Nature which has not yet been given life, into relation with what salts are, what the particular quality of a vaporising metal is, and what readily combustible substances are.
A polarity of the same sort exists between the human organism and what constitutes the vitally active forces in the external plant world. When we take up a plant into us in such a way that it simply gives off some particular substance, which is taken up by us as lifeless matter and acts as such in us, the real plant-nature may then be left out of account in the human being. On the other hand, the plant element may also be taken up by the human organism in such a way that it goes on working in its own peculiar character as plant, that is, the external vital activity of the plant continues to work as the same sort of external vital activity which works in the plant. In this case that process cannot take effect which otherwise always goes on at the border line between the physical nutritional substances and the ether-body. For the ether-body is akin to the plant; and the plant is “plant” precisely by reason of the fact that it has an ether-body. The plant-nature is simply caught up at the point where the nutritional stream is seized upon by the ether-body, so that whatever of the plant-nature works into the human organism cannot be taken into account so long as it is in the alimentary canal, but only in those organs involved in the processes to which the ether-body already has its relationship and into which the astral nature of man also works. For this reason the external plant-activity begins its work only when it reaches the inner cosmic system and the sympathetic nervous system and, in so far as it is involved with these, also the lymph-system. The plant-nature no longer extends to the point where the human being opens himself, through the blood, to the outer world. The plant-element is fitted to the central, more inward part of the human being; so that whatever may be sought in the plant-nature in the way of vital activities, capable of combating the excessively strong inner vital activities of the functions of our organism, cannot have any effect at all upon whatever belongs to the material substance in the seven organs of our inner cosmic system and in the corresponding organs of the head, and which nourishes itself in these organs; it can act only upon whatever pertains to the activities, the functions of these organs. When these functions are disturbed, when they act abnormally, without our being able to say that they are over-nourished or under-nourished, then the vital activity of the plant-nature comes into question. Hence, when an excessive activity of the organs is manifest, we can combat this with something taken out of plant-nature but capable of working in only as far as the seven organs, as far as the boundary of the lymph-system and the blood-system.
It is impossible to go further into the combating of irregularities in the human organism, not so much because we should in any case have insufficient time as because it is better for the Anthroposophist to hold aloof from everything which is at present still involved in partisan strife. What we have thus far set forth is not involved in conflicts where there is far too much fanaticism. For at most people can take it for pure nonsense, in which case it will share the same fate which for many is to be that of Anthroposophy in general: namely, that it has no worth whatever. Anthroposophy would have to keep silent if it wished not to speak about those things which appear nonsensical to people who are not willing at the present time to accept it. But, if it were to proceed further and investigate the effect of the animal element upon the human organism, we should very quickly become involved in strife.
One thing, however, you will have perceived: that this human organism is a complicated system of individual organs and instruments which stand at various stages of evolution, these stages differing very greatly among themselves, and which are connected in the greatest possible variety of ways with the organism as a whole. What it is that works into this physical organisation of man, which we see with our eyes and grasp with our hands, in order that the nutritive substances may organise themselves suitably, may be ordered according to the various organs, this cannot be seen with the external eye but it is disclosed to the spiritual eye of the seer. Everything that has displayed itself before us in the human organism we must look upon as one single system, wherein appears both what is young and what is old. We have brought out this fact in individual examples, for instance, in the fact that the brain shows itself as an older organ and the spinal cord as a younger one; and in the fact that the brain was once a spinal cord and has transformed itself out of that. Then, too, we have seen that our complicated digestive system forms, together with the blood-system, one single system which is old and has been metamorphosed; whereas in the lymph-system which cannot take up substances from without but can as yet open only inwards to the material supplied by the inner tissue, we have a younger system in comparison with the combined digestive and blood-system, just as we have in the spinal cord an organ that is younger than the brain. And this, again, is a very important viewpoint. When we look at our lymph-system and all that goes with it we have before us something which, if it were not embedded there as a lymph-system, and did not remain shut off but opened itself to the more advanced stage of its evolutionary process, would progress to a digestive system and blood-system as the spinal cord evolved to the brain. Thus the digestive-blood-system presents to us a lymph-system that has been metamorphosed out of the substances and tissues of the body, substances and tissues which, as we know, have to be changed in the body before they can take on the form which they have inside the man; whereas the lymph-system, as we have it, is employed to take up the substances that are produced inside. In the lymph-system and what pertains to it, we have a simpler digestive system and a simpler system for mediating consciousness. On the other hand, a system more complicated than the lymph-system, opening not only to the inner but also to the outer world, is what we have in the metamorphosed lymph-system, the digestive and glandular systems.
Everything that appears later, during the course of evolution of any living creature, is laid down beforehand in the germinal plan. What I have here explained to you as the complicated human organisation exists potentially in the germinal plan of the human being as it builds itself up, when once it is produced through the process of impregnation. If we retrace the course, so to speak, from this fully-formed man to the germinal plan, we are able to discover that inside this same life-seed or germ complicated systems of organs in miniature, scarcely visible at first, even to microscopic examination, are present, as the very first plan; present in such a way indeed, that the organs even at that time already reveal just how they are related to one another.
Once we observe that the outermost enclosure of the human being is the boundary of the skin which leads us on to the sense-organs embedded therein, and observe also how these sense-organs are organised so as to extend inward to the nervous system, we shall realise that everything present in the outermost boundary of man must have been transformed out of something else, for this is already very complicated in itself. (The brain, for instance, belongs to this system; to imagine a brain which is not first prepared through other organs, and transformed out of these, is impossible.) We must think therefore of the outer sheath of the human being as it appears to-day, as the product of a transformation from those organs which are its groundwork, as having passed through a transformation similar to that of the brain out of the spinal cord, and to the digestive-blood-system with all its accessories, out of the lymph-system.
Now, it is precisely in everything which we have observed as the brain, that we have a transformed spinal cord system. But here again this spinal cord system shows itself to us at the present time in such a way that we can see that it is an organ in a descending evolution, so to speak. In those organs, accordingly, which represent earlier stages, we have organ-systems formed later and at the same time in a descending evolution. This we must apply also to the lymph-system. In that which confronts us in the human being as the lower man, thought of spatially, we have, in the antithesis, lymph-system and digestive-blood-system, something which transforms the lymph-system into the digestive-blood-system. We must understand clearly, to be sure, that the blood-system itself is such a complicated inward-coursing system that it reveals, even in its very configuration, the fact that it is itself the product of a transformation of a still earlier state, the product of a twofold metamorphosis. On the other hand, that which reveals to us that it has gone through its transformation only once, an opening outward, is the digestive canal. We may therefore say that, if we were to move the digestive canal more inward, we should keep this whole organic system shut up inside, as far as the activity at present characteristic of the lymph-system through which only that is taken up from the inner product which is secreted by the tissues.
Thus in the outer boundary of man, the skin-system, we have the metamorphosis of another system; and in the digestive system likewise we can see the transformation of another organ-system out of which it has developed, and which is itself to-day in a descending process of evolution. According to the whole nature of the organ-systems as they present themselves to us we have to seek, therefore, for their first or primal plan in such a way that we feel everything we see as the germinal design containing the skin- and the sense-organs and nervous system—to be the redisposition of another system which is to-day inside the organism and in a descending evolution, just as the digestive system in its design is a redisposition of another inner system which is now in a descending evolution. Thus we have, at the present time, both an ascending and a descending evolution already indicated in the “life-seed” of man.
And so we may trace the whole human organism back to a scheme or plan where everything in the separate organs is prepared in the germ. And, in fact, we do see in the human germ which comes into existence through the process of impregnation that in the four superimposed germ-layers (the outer germ-layer or exoderm, the inner germ-layer or entoderm, and the outer and inner middle layers or mesoderma) the four principal systems of the human organism are actually already present, pre-modelled in this germinal plan. Furthermore, in accordance with our evolution we shall have to consider the outer germ-layer, which, in contemporary anatomy or physiology is called the skin-sense layer, as the product of a metamorphosis which reveals to us its original plan in the outer middle layer. In the outer mesoderm, that is, we have as an embryonic plan in a descending evolution, what appears at a higher stage in the skin-sense-layer; and in the inner middle layer we have in a younger formation and in a downward evolution, what appears in the inner layer or entoderm as the intestinal glandular-layer. When we observe the human germ in its evolution we have in the two middle germ-layers, in what external physiology calls the mesoderma, the original plan of the human being still recognisable; whereas the two external germ-layers, exoderm and entoderm, are layers which have undergone a metamorphosis. The two middle layers reveal to us the original state, whereas the two others reveal higher evolutionary stages of this state. And it is only an illusion when external microscopic research does not accurately state the facts of the case.

Now we know that this germinal plan, this life-seed, is formed through the flowing together of two tendencies, the feminine and the masculine, and that the complete germ can only come into being through the living interaction of the two. In both these germinal tendencies, accordingly, there must be included all the processes which, through interaction, form the one single embryonic plan for the complete human organisation.
What does occultism reveal to us regarding the interaction of the male and the female germs?
It shows us that the female organism, under the conditions of our age, is capable of producing only such a human germ as would be unable, if it were to follow a completely isolated evolution, to develop what we call in its broadest sense the “form-principle.” That which leads, therefore, to the final stage of the bony system, thus giving complete firmness to the human being, and which also brings about the final unfolding into a skin-and-sense-system as we have it to-day, could not be supplied through the female contribution. The contribution of the woman is such as to justify one in saying: “What it would bring forth would be too good for this earthly world as it is to-day; for there are not present in our external world all the processes which could serve such an organism, if it were to evolve itself in accordance with the tendency of the woman's contribution to the whole human organism.” It should not be necessary for the human organism derived from the woman to proceed so far as to be of this earth, as we may say, which is the case in the dense deposit of the bony system; it should not be forced to unfold itself in a way that enables it to look out into the present physical world through the senses. On the contrary, it should be enabled to have its inner support in softer material, as it were, than our solid bony system. It ought, furthermore, to be free not to open its eyes so wide toward the outside world, or to open its other senses outward, to the same degree as is the case with the human being of to-day, but to remain with its perceptions more enclosed in its inner life. This represents the female portion of the common human organism: a germinal plan which tends to shoot forward beyond the limit of what is possible in our present earth existence. And this simply because, in the physical earth-conditions of to-day, we have not the requirements essential to so refined an organism, one so little adapted to be of this earth, in the way the bony system is, or to unfold itself outward. Such an organism, under natural conditions, is from the very beginning predestined to death. That is to say: by reason of that which the woman's organism is of itself unable to imprint upon the human embryo, this embryo is from the beginning doomed to death.
The other portion which is added to the germinal plan is the male element, and this is in exactly the reversed situation. If the male germ alone were to bring forth the human being, the progress of that organisation which lives its life in an opening of itself outward, as is the case in the skin-sense-system and in the powerful development of what leads to the solidification of the bony system, would overshoot the mark in the opposite direction. The male organisation would be just as little able as the female to create of itself an embryo capable of living. Of itself alone it would just as certainly create a dead embryo as would the female organisation because that which it could create, which it could contribute to the germ-plan, would be so organised, if it were to unfold its forces of itself, that it would have to vanish in view of the conditions actually existing on the earth at the present time; for it would unfold forces which are simply too powerful for such conditions, so that it could not exist as organic life within the confines of this world. That is to say, the male element of the germ does not really come into existence at all; it can act only through co-operation with the female germ. That which stimulates the female germ-plan too intensely, carrying it too far beyond what is possible on the earth, leads the male germ-plan too far downward, below what is possible on the earth. Whatever is destined to death in this female germ, through the excess of those forces which, if they could find any approach at all to the sense-world, would ultimately lead to a breaking up, a failure to grow together with the external world, this balances itself with the male germ through the process of impregnation. The forces that are compressed into the male germ-plan, if these were ever to accomplish their growth alone, would lead the whole thing immeasurably below the earthly, would bring the human organisation to a far greater terrestrialising of the bony system, and to an entirely different unfolding of the senses and taking up of the outer world, than is the case to-day. These two organic tendencies must in their very first beginning blend and come together; for, under earthly conditions, either one of them alone is from the first predestined to death, and only the living interaction of what otherwise gushes over the limits in both directions gives us that human embryo which alone is suited to earthly life.
Thus we see that we have been able, although only in a sketchy way, to comprehend things as far as this point, where the human being is capable of bringing forth his kind. We could go much further by throwing light also upon all the details of the embryonic process. And the more profoundly we should illuminate these, the more we should see that the most minute as well as the most glaring facts, including what has been said here regarding the super-sensible force-systems in the germinal plans, verify themselves in the outward expression of these force-systems, in what the human being develops in order that his race may live over all the earth so long as it is going through its present processes.
We have seen at the same time, however, that the earth gives us its densest terrestrialising process, so to speak, in what we call the tendency to the bony system, and its most vitally active process in what we call the human blood-system. And it need be added only very briefly that everything which goes on on the earth in the external physical human organism, in so far as this is visible, forces its way up as it were, into those processes which take place in the blood. And these processes are warmth processes. We have, therefore, in these processes the direct expression of the activity of the blood as the instrument of the ego, of the highest level, that is, of the human organism. Below this are the other processes; uppermost is the warming process, and in this there takes hold, directly, the activity of our soul and our ego. It is for this reason that we feel, with regard to so many activities of the soul, what we may call “the transmutation of our soul-activities into a kindling of inner warmth,” and this may extend its effects even to a becoming physically warm in the process of the blood. Thus we see how, from out the soul and spirit by way of the warmth-process, there takes hold down into the organic, into the physiological, what is directed from above. We might show, in connection with many other facts of the external world, how the psychic-spiritual comes into contact in the warmth-process with the physiological, with what occurs behind the physiological. In the warming process, accordingly, we have a transformation of the organic systems in their activities. We find the most manifold transformations in the complicated apparatus of soul and spirit in man; but this physical human organism reaches up as far as the warmth process.
Does this transformation cease at this point? Does that which confronts us as the inheritance of the bony system, proceeding from below upward, extend only thus far? Everywhere, below the warmth process, we have transformation; from below upward it reaches as far as the warmth process. What then follows can here only be indicated and then left to the further reflection and feeling of the listeners.
What the organism produces in the way of inner warmth processes in our blood, warmth processes which it conducts to us through all its different processes, and which it finally brings to expression in a flowering of all other processes, penetrates up into the soul and spirit, transforms itself into soul and spirit. And what is it that is most beautiful about the psychic-spiritual? The most beautiful, the loftiest thing about it, is the fact that, through the forces of the human soul, what is organic can be transformed into what is soul nature! If everything that man can have through the activity of his earthly organism is rightly transformed by him after it has become warmth, it then transmutes itself in his soul into what we may call an inner living experience of compassion, a sympathy for all other beings. If we penetrate through all the processes of the human organism, to the highest level of all, to the processes of warmth, we pass as it were through the door of the human physiological processes, above the uppermost heights which are formed by these processes into that world where the warmth of the blood is given its worth in accordance with what the soul has made out of it: in accordance with the living sympathy of the soul for everything that has being, and its compassion for everything around it. In this way we broaden our life, if our inner life carry us on to a kindling of inner heat, beyond all that is earthly being; we make ourselves one with all earthly being. And we must note the marvellous fact that the whole of Cosmic Being has taken the round about path of first building up our whole organisation, in order finally to give us that warmth which we are called upon to transmute through our ego into living compassion for all beings.
In the Earth's mission, warmth is in the process of being transmuted into compassion.
This is the meaning of the earth process; and it is being fulfilled, since man as a physical organism is embedded in this earth-process, through the fact that all physical processes finally come together in man's organisation as their crown; that everything therein, like a microcosm, in turn, of all earthly processes, opens again into new blossoming. And, as this is transmuted in the human soul, the earth-organism, through man's sympathetic interest and living compassion for every kind of being, attains to that for which warmth had its intended use in the organism allotted to him as Earth-Man. What we take up in our souls through living sympathy, which helps us to broaden our inner soul-life more and more, we shall take with us when we shall have gone through many organisations such as enable us to use to the full, for the spirit, everything that the earth could give us as kindling heat, burning warmth, flame of fire! And when, through innumerable incarnations, we shall have taken up into ourselves all that there is of this fervour of warmth, then will the earth have reached its goal, its purpose. Then will it sink beneath us, a great corpse, into indeterminate cosmic space; and there will arise out of this earth-corpse the united throng of all those earthly human souls who, through their different earthly incarnations, have realised the worth of the outpouring warmth of earth-organisms by transmuting it into living compassion and sympathy, and into whatever can be built upon these. Just as the individual soul, when the human being passes through the portal of death, rises to a spiritual world and gives over the corpse to the forces of the earth, so to the forces of the cosmos will one day be surrendered the earth's corpse, when it shall have given to us that burning warmth we needed for the compassion which was the foundation-stone of all our higher activities of soul. This corpse which will be given over to the cosmic system, just as the individual human corpse is given over to the earth-system, will be able to see rising above it the sum of all the individual human souls, now one important stage nearer perfection as a result of earth existence, and these will then press onward to new stages of existence, to new cosmic systems. Just as in the earth-system the individual human being, after he has passed through the portal of death, advances to new incarnations, so does the throng of all the individual souls, after the earth-corpse has fallen away, advance to new planetary stages of existence.
And so we see that nothing in the cosmic system is lost, but that what is given to us in our organism up to the final blossoming of heat is that “material” which, when we have used it up as burning warmth, helps us to find the way to a new and higher stage leading to eternity. Nothing in the world is lost, but what the earth produces, through human souls, is carried over by them into eternity!
Thus does spiritual science also permit us to connect the physiological processes in the human organism with our eternal destiny. And thus will this science, if we view it as something which must so implant itself within us that it is not mere theory or abstract knowledge, fill us with all those forces which show us that we as human beings do not, after all, stand only upon the earth, but in the whole cosmic system! If we learn to think thus about the lofty and eternal destiny of humanity, how man takes the forces of the earth in order that he may work on into eternity, we then receive through spiritual science what must be wrung out of it, not only what we may attain for the sake of knowledge but for our whole man. And if those human beings who divine or already possess this high ideal of knowledge come together in a true brotherhood, harmoniously united in striving toward the highest of all, who understand each other, that is, in their innermost being, this means that there are present on our earth, in its process of becoming, human beings who have the right to be conscious that they bear within themselves seeds which are developing, which can be fruitful for the further evolution of earth and humanity. In all modesty may anthroposophists come together and unite their feelings with what is highest, most universal, in man. And, when men gather in such a spirit, they understand one another in their deepest being; for they acknowledge one another, not merely as individual earth-men and in their earthly destiny, but rather in their eternal destiny.
It was in this spirit that we came together here; and it is in this spirit that we shall go away again, to live in the outside world and perhaps to pass on to others much of what it has been possible to give here as an incentive, even if only in outline, and thus to bring it to new flower. We shall at the same time strive so to work when we are scattered that, although physically separated, we shall be in harmony with one another in living thought, in feeling, and in all our willing. Then shall we be rightly united in that Spirit which ought to be brought to mankind through Anthroposophy. In this Spirit we are about to separate after having been together for a while; in this Spirit we shall remain united in soul; and in this Spirit we shall meet again when it is meant to be.
Achter Vortrag
Es wird heute in diesem letzten Vortrage meine Aufgabe sein, die Betrachtungen der letzten Tage über okkulte Physiologie, die manches, wenn auch zum Teil recht skizzenhaft, von den Vorgängen der menschlichen Organisation darzustellen versuchten, zu einer Art von Gesamtbild zu vereinigen, das ja wieder nur skizzenhaft sein kann, durch das wir in den Stand gesetzt werden können, eine Anschauung zu bekommen von dem lebendigen Leben und Weben des menschlichen Organismus. Wir werden dabei am besten tun, wieder von dem gröbsten auszugehen, von der Wechselbeziehung zwischen dem menschlichen Organismus und der äußeren Welt, unserer physischen Erde, in der Aufnahme der Nahrungsstoffe.
Diese Nahrungsstoffe werden ja, nachdem sie aufgenommen sind, in der mannigfaltigsten Weise umgewandelt und stufenweise so umgeändert durch die verschiedenen Organwirkungen, daß sie hingeleitet werden können zu den einzelnen Gliedern des menschlichen Organismus, zu den einzelnen Systemen der menschlichen physischen Wesenheit. Es ist ja nicht schwer einzusehen, daß alles, was aus den Nahrungsstoffen im menschlichen Organismus wird, im Grunde genommen den Menschen, wie er vor uns steht in der physischen Welt, eigentlich erst zum physischen Menschen macht. Es liegt hier ja allerdings eine gewisse Schwierigkeit für das Verständnis vor. Allein, wenn wir Ernst machen mit den bisher eingehaltenen Prinzipien und die übersinnliche Erkenntnis wirklich auf die Betrachtung des Menschen anwenden, so müssen wir sagen, daß es nur die Nahrungsstoffe sind, die von der äußeren Welt substantiell in den menschlichen Organismus aufgenommen werden. .Alle übrigen auf den Menschen einwirkenden Einflüsse haben wir uns im Grund genommen zu denken als übersinnliche, unsichtbare Kräfte. Wenn sie sich für einen Moment alles wegdenken, was den menschlichen Organismus, von den Nahrungsstoffen herrührend, ausfüllt, so behalten Sie in physischer Beziehung noch weniger — verzeihen Sie den trivialen Ausdruck -, viel weniger übrig als einen leeren Sack, nämlich gar nichts. Denn auch was an Haut, an Umhüllung des physischen Organismus vorhanden ist, ist nur dadurch vorhanden, weil entsprechend verarbeitete Ernährungsstoffe an die betreffenden Partien hingeführt worden sind. Rechnen Sie die Nahrungsstoffe und was aus ihnen wird, weg, so haben Sie dahinter den menschlichen Organismus nur als ein übersinnliches Kraftsystem zu denken, das die Verteilung der assimilierten Nahrungsstoffe nach allen Richtungen hin bewirkt. Wenn Sie diesen Gedanken, wie er jetzt ausgesprochen worden ist, sich so richtig vor die Seele stellen, so werden Sie sich sagen: Eines ist aber eigentlich die Voraussetzung, bevor irgend etwas, auch das kleinste, von den Nahrungsstoffen aufgenommen werden kann, denn diese Stoffe können nicht von der Außenwelt in jedes beliebige Wesen hineinbefördert werden, damit dasjenige in ihm vorgehe, was im menschlichen Organismus vorgeht. Es muß der Mensch schon bei der allerersten Nahrungsaufnahme den physischen Nahrungsstoffen eine innere Kraftwirkung entgegenstellen können, welche aus der übersinnlichen Welt stammt, und es muß in diesem inneren Kräftesystem der Mensch als solcher schon enthalten sein. Im Okkultismus nennen wir dasjenige, was so den eigentlichen physischen Ausfüllungsmaterialien vom Menschen zunächst entgegengehalten wird, was durchaus schon übersinnlich zu denken ist, das nennen wir im umfassendsten Sinne die menschliche Form. Wenn wir uns die allerunterste Grenze der menschlichen Organisation denken, so müssen wir uns vorstellen, daß sich gegenüberstehen die physische Materie und die übersinnliche Form, welche als ein aus den übersinnlichen Welten herausgeborenes Kraftsystem dazu bestimmt ist, die Materie aufzunehmen - nicht wie ein physischer Sack oder Balg, sondern wie ein Überphysisches, ein Übersinnliches - und dasjenige herauszubilden, was überhaupt den Menschen erst physisch-sinnlich erscheinen läßt. Erst dadurch, daß sich dieser übersinnlichen Form eingliedert das assimilierte Ernährungsmaterial, wird der sonst rein übersinnliche menschliche Organismus zu einem physisch-sinnlichen Organismus, den man mit Augen sehen und mit Händen greifen kann. Man nennt das, was so entgegengehalten wird der physischen Materie, aus dem Grunde «Form», weil eigentlich in aller Natur ein solches Gesetz wirkt, ein genau gleiches Gesetz, das überall «Formprinzip» genannt wird. Wenn wir die äußere Welt betrachten, so finden wir, daß bis zum Kristall hinunter überall das Formprinzip tätig ist. Die Substanzen, welche in den Kristall eintreten, müssen, um das zu werden, als was der Kristall sich darstellt, gleichsam eingefangen werden von dem Formprinzip, und dieses macht mit Hilfe der Substanzen den Kristall erst zu dem, was er ist. Nehmen Sie zum Beispiel das Kochsalz, Chlornatrium, so haben Sie als physische Substanzen miteinander verbunden Chlor und Natrium, ein Gas und ein Metall. Sie werden leicht einsehen, daß diese beiden Stoffe, so wie sie sind, bevor sie eingefangen werden durch eine formende Wesenheit und dadurch erst zu einer chemischen Verbindung in Würfeln kristallisiert erscheinen, jede für sich völlig andere Formen zeigt. Bevor sie eintreten in dieses Formprinzip, haben sie nichts Gemeinsames; aber sie werden eingespannt, aufgenommen von diesem Formprinzip, und dieses bildet den physischen Körper Kochsalz.
So setzt auch alles, was als umgewandelte Nahrungsstoffe im menschlichen Organismus erscheint, die unterste übersinnliche Wesenheit, die übersinnliche Form voraus. Wenn nun neue Ernährungsstoffe in den menschlichen Organismus eintreten sollen, der durch das Wirken des Formprinzips bereits nach außen abgegrenzt ist, so müssen sie unter normalen Verhältnissen durch den Mund in den Ernährungskanal aufgenommen werden. Dabei machen sie gleich schon vom Munde ab die allererste Umwandlung durch. Durch den Ernährungskanal werden weitere Umwandlungen bewirkt. Diese Ummwandlungen kompliziertester Art könnten nicht bewirkt werden, wenn nicht dem menschlichen Organismus ein höheres Prinzip eingegliedert wäre, das wir Formprinzip genannt haben, durch dessen Wirksamkeit die Nahrungsstoffe — die zunächst, wenn sie aufgenommen werden, sich zueinander neutral, gleichgültig verhalten — modifiziert würden, so daß sie in die Lage kommen, lebendige Organe zu bilden. Wir können uns, obgleich es beim Menschen ein ganz anderer Prozeß ist, weil er auf einer anderen Stufe geschieht, diese Umwandlung der Nahrungsstoffe im menschlichen Verdauungskanal vergleichsweise so vorstellen, wie wenn die Pflanzen ihre Ernährungsstoffe aufnehmen aus dem mineralischen Boden und sie dergestalt umwandeln, daß sie sich zu der Form der betreffenden Pflanze aufbauen. Da ist nur möglich, weil bei der Pflanze der Ernährungsstrom von einem Lebensprozeß oder, wie wir im Okkultismus sagen, vom Ätherleib als dem ersten übersinnlichen Prinzip aufgenommen wird. So werden auch beim Menschen die in den Organismus eintretenden Nahrungsstoffe vom Ätherleibe bearbeitet, das heißt, der Ätherleib sorgt für ihre Umwandlung, für ihre Eingliederung in die inneren Gesetzmäßigkeiten des menschlichen Organismus. So haben wir also dieses erste übersinnliche Glied des Menschen, den Ätherleib, anzusehen als den Erreger der ersten Umwandlung der Nahrungsstoffe. Wenn nun diese Nahrungsstoffe soweit umgewandelt sind, daß sie in den Lebensprozeß aufgenommen sind, dann müssen sie in dem Sinne, wie wir es in den vorhergehenden Vorträgen geschildert haben, weiter verarbeitet und dem menschlichen Organismus angepaßt werden. Sie müssen so verarbeitet werden, daß sie nach und nach denjenigen Organen im menschlichen Organismus dienen können, die ein Ausdruck der höheren übersinnlichen Prinzipien sind, des Astralleibes und des Ich. Kurz, wir müssen uns klar sein, daß die höheren Prinzipien, Astralleib und Ich, die eigentümliche Art ihrer Regsamkeit hinuntersenden müssen bis zu den Vorgängen in den Organen des Ernährungs- und Verdauungsapparates und daß sie bis in die verwandelten Nahrungsstoffe hinab wirken müssen.
Da stellen sich nun dem Nahrungsstrom diejenigen Organe entgegen, welche uns schon bekannt sind, die wir bezeichnet haben als die sieben Organe des inneren Weltsystems. Wir zeichnen nochmals ganz schematisch das innere Weltsystem des Menschen:
Die Nahrungsstoffe werden also aufgenommen und zunächst in der mannigfaltigsten Weise umgearbeitet im Verdauungskanal, dann stellen sich ihnen entgegen Leber, Galle, Milz, Herz, Lunge, Nieren und so weiter. Wenn wir uns nun darüber klar sind, daß diese Organe durch die ihnen entsprechenden Kraftsysteme dazu bestimmt sind, den Nahrungsstrom weiter umzuarbeiten, so können wir fragen: Welches ist der Sinn dieser weiteren Umwandlung? — Wenn der Nahrungsstrom nur so weit bearbeitet würde, wie es im Verdauungskanal geschieht, um der Lebensform dienen zu können, so würde der Mensch nur ein unbewußtes Pflanzendasein führen können, denn er hätte es nicht zur Ausbildung solcher Organe gebracht, die Werkzeuge sein können für seine höheren Fähigkeiten. Die sieben Organe wandeln den Ernährungsstrom aber weiter um, und wir wissen, daß diese Vorgänge durch das sympathische Nervensystem davon abgehalten werden, in das menschliche Bewußtsein einzutreten. Daher haben wir in dem sympathischen Nervensystem mit den sieben Organen zusammen dasjenige, was sich dem Nahrungsstrom entgegenstellt.

Damit sind wir schon bis zu einem hohen Grade von außen in das Innere des menschlichen Organismus hineingedrungen. Aber das, was da drinnen vorgeht, man möchte sagen als die gegenseitige Angelegenheit der sieben Organe, da ist etwas, was nirgends in unserer Erdenwelt so vorgehen könnte wie da drinnen. Es kann nur dadurch so vorgehen, daß dieses Innere von der Außenwelt völlig abgeschlossen ist und für diese Tätigkeit des Innern die Stoffe vorbereitet sind durch den Verdauungskanal. Also wir stehen damit schon im Inneren des menschlichen Organismus darinnen.
Nun haben wir das Eigentümliche zu verzeichnen, daß, indem wir so im Innern des Organismus darinnenstehen, der Organismus sich ja selbst innerlich organisieren, sich selbst innerlich differenzieren muß. Um allen diesen an ihn herantretenden Anforderungen zu genügen, muß der Organismus eine Vielheit zusammenwirkender Organe herausbilden. Für die mannigfaltigen inneren Verrichtungen ist gerade diese Vielheit der Organe notwendig. Was durch diese erreicht werden muß, werden wir im folgenden sehen. Wenn wir uns denken, daß nur der Nahrungsstrom umgewandelt würde durch die sieben Organe des inneren Weltsystems, da würde der Mensch nimmermehr . sein Wesen dem Bewußtsein aufschließen können. Er würde nicht einmal die dumpfeste Form des Bewußtseins haben können, weil ja alles, was da vorgeht, verhüllt wird, abgehalten wird vom Bewußtsein durch das sympathische Nervensystem. Es ist also eine Verbindung notwendig zwischen diesen sozusagen von außen her aufgebauten inneren Organsystemen und dem, was weiter im Inneren des menschlichen Organismus ist. Diese Verbindung wird dadurch hergestellt, daß in der Tat durch alles das, was der Ernährungsprozeß in seiner Ganzheit gibt, die gesamte Form des menschlichen Organismus durchzogen wird von dem, was wir im weitesten Sinne Gewebe nennen. Eine gewisse Art von Gewebe einfachster Organisation durchzieht alle einzelnen Glieder der menschlichen Wesenheit, das fähig ist, sich so umzuwandeln und auszugestalten, daß sich die verschiedensten Organe herausbilden können. Gewisse Arten des Gewebes zum Beispiel bilden sich so um, daß sie sich durch Einlagerung besonderer Zellen zu den Muskeln umgestalten; andere bilden sich so um, daß sie fest werden und sich die Knochenzellen einlagern, indem sie die entsprechenden Substanzen sich aneignen. So daß wir in den einzelnen Organen des menschlichen Organismus stets an das zu denken haben, was ihnen zugrundeliegt, nämlich das den Körper nach allen Richtungen durchziehende Gewebe, aus dem die einzelnen Organe sich herausbilden. Dieses bildungsfähige Gewebe würde aber, wenn es noch so sehr zu wachsen und die verschiedensten Organe aus sich herauszubilden imstande wäre, doch nichts anderes darstellen als im Grunde nur etwas Pflanzenhaftes; denn das ist ja das Wesentliche des Pflanzenhaften, daß die pflanzlichen Wesen wachsen, daß sie aus sich Organe hervortreiben und dergleichen. Indem sich aber der Mensch über das Pflanzenhafte hinaus erhebt, muß sich uns ein ganz neues Element darbieten, durch welches der Mensch in die Lage kommt, zu dem Pflanzenleben dasjenige hinzuzufügen, was ihn über das Pflanzenleben hinaushebt. Der Mensch muß hinzufügen das Bewußtsein, zunächst die einfachste Form des Bewußtseins, das dumpfe Bewußtsein, das ihn fähig macht, das eigene innere Leben wahrzunehmen. Solange nicht ein Wesen das eigene innere Leben bewußt miterlebt, solange es noch nicht in der Lage ist, sich innerlich gleichsam zu durchspiegeln, um dieses eigene innere Leben mitzuerleben, so lange können wir nicht sagen, daß es sich über die Pflanzenhaftigkeit hinauferhebt. Erst dadurch erhebt sich ein Wesen über die Pflanzenhaftigkeit hinauf, daß es nicht bloß in sich Leben hat, sondern dieses Leben bewußt erlebt, daß es zunächst diese inneren Vorgänge durchspiegelt und miterlebt.
Wodurch kommt nun überhaupt Erleben zustande? Dafür haben wir uns schon den Begriff gebildet. Wir haben ja in den früheren Vorträgen schon gezeigt, daß Erleben zustande kommt durch Absonderungsprozesse. Deshalb werden wir als die Grundlagen des inneren Erlebens, des dumpfen, die inneren Lebensprozesse durchziehenden Bewußtseinserlebens, Absonderungsprozesse suchen müssen. Wir werden voraussetzen müssen, daß überall aus den Geweben heraus Absonderungsprozesse stattfinden; und in der Tat treten uns diese Absonderungsprozesse schon bei der äußeren Betrachtung des menschlichen Organismus entgegen, wenn wir sehen, wie fortwährend Stoffe aus allen Teilen des Gewebes aufgenommen werden durch das, was wir die Lymphgefäße nennen, die wie eine Art anderes System neben dem Blutsystem den ganzen Organismus durchziehen. In das Lymphgefäßsystem münden sozusagen von allen Bezirken des menschlichen Organismus diejenigen Absonderungsprozesse, welche das dumpfe innere Erleben vermitteln. Könnten wir uns einmal in abstracto das gesamte Blutsystem wegdenken und könnten wir uns das Gewebe so denken, daß es nichts mehr hat von blutartigem Charakter, so würden wir uns vorzustellen haben, daß im Blutsystem sich höhere Prozesse abspielen gegenüber den Prozessen des Lymphsystems. In diesen Absonderungen fühlt der Mensch gleichsam in einem dumpfen tierischen Bewußtsein seinen eigenen physischen Leib. Dumpf durchspiegelt er seine Organisation. Und ebenso wie auf der einen Seite durch das sympathische Nervensystem von dem Bewußtsein alles abgehalten wird, was vom Verdauungs- und Ernährungsprozeß und den sieben Organen heraufdringen will, so wird auf der anderen Seite gleichsam durch Rückstrahlung der Tätigkeit des sympathischen Nervensystems, durch Verbindung und Wechselwirkung mit den Lymphbahnen, ein für den heutigen Menschen allerdings vom hellen Tagesbewußtsein überstrahltes dumpfes Bewußtsein ausgebildet. Es wird überstrahlt vom hellen Tagesbewußtsein des Ich, wie ein schwaches Licht überstrahlt wird durch ein starkes. Dieses dumpfe Bewußtsein ist gleichsam die andere Seite jenes Bewußtseins, das sich des sympathischen Nervensystems als seines Werkzeuges bedient.
Würde der Mensch seinen Organismus nur entwickelt haben bis zur Bildung des Körpergewebes und der Organe, die für die inneren Verdauungsvorgänge und für die Absonderungen in die Lymphbahnen notwendig sind, so würde er nur ein dumpfes Bewußtsein seines Innenlebens vermittelt erhalten können. Er würde aber nicht eine Ausbildung des Ich-Bewußtseins erreichen können; das kann er nur erwerben, wenn er sich nicht bloß in seinem Inneren erlebt, sondern sich auch nach außen aufschließt. Hier haben wir wiederum ein Sichaufschließen nach außen zu verzeichnen. Wir haben ja schon früher davon gesprochen, wie es dem Menschen durch die Atmung möglich wird, unmittelbar mit der Außenwelt in Verbindung zu treten. Jetzt können wir weitergehen und sagen: Sofern wir den inneren Menschen betrachten, dürfen wir eigentlich nur bis zum Verdauungssystem gehen, denn wir können sagen: Insofern Ausläufer der Organe des inneren Weltsystems bis zum Verdauungskanal sich hinwenden, haben wir in diesem Anstoßen des inneren Weltsystems an den Verdauungskanal schon ein Sichaufschließen nach außen zu sehen, denn der Mensch ist gleichsam bereit, Nahrungsstoffe von außen aufzunehmen. Indem er mit aus der Umwelt entnommenen Nahrungsstoffen in enge Berührung tritt, ist er eigentlich schon nicht mehr nur innerlich. Ein weiteres Sichaufschließen nach außen haben wir kennengelernt in der Atmung, und in noch höherem Maße ist es zu erkennen in jenen Organen, die den seelischen Funktionen dienen.
So also sehen wir, wie dem bewußten Leben des Menschen zugrundeliegt einerseits ein dumpfes Innenleben, andererseits die Fähigkeit, sich der Außenwelt aufzuschließen, mit der Außenwelt Verbindung zu haben. Dadurch erst kann der Mensch ein Ich-Wesen sein. Nur dadurch, daß er nicht nur die Widerstände in seinem eigenen Innern in seinen Absonderungsprozessen spürt, sondern auch die Widerstände, die die Außenwelt ihm entgegensetzt, kann der Mensch sein Ich-Bewußtsein entwickeln. So ist in der Tatsache, daß sich der Mensch auch wieder nach außen aufschließen kann, die Grundlage gegeben für die physische Ichheit des Menschen. Damit aber muß der Mensch auch die Möglichkeit haben, in der mannigfaltigsten Weise das Organ dieser Ichheit auszubilden. Und wir haben ja gesehen, wie in der Tat das Organ der Ichheit, das Blut, sich eingliedert in den Organismus und wie der Blutkreislauf alle Organe durchzieht, um ein Werkzeug zu sein für die Ichheit. So wie die Ichheit geistig-seelisch den gesamten Menschen durchlebt und durchwebt, so durchzieht physisch der Blutkreislauf den gesamten menschlichen Organismus und wendet sich dabei gleichsam nach zwei Seiten, nach dem Innenwesen des Menschen mit den sieben Organen und so weiter, und dann haben wir wieder ein Sichaufschließen nach außen, ein In-Verbindung-Treten mit der äußeren Welt. Wir können also im höchsten Sinne des Wortes von einem Kreislauf der Kräfte sprechen, welche hinter den physischen Erscheinungen stehen und welche durch das Ich einen Verbindungspunkt finden.
Nun müssen wir uns einmal mit den einzelnen Phasen dieses Kreislaufes noch etwas beschäftigen. Da handelt es sich ja zunächst darum, daß wir noch einmal den Ernährungsprozeß verfolgen, das Aufnehmen der Nahrungsstoffe, welche dadurch, daß sie vom Ätherleibe oder vielmehr von der Kraft des Ätherleibes ergriffen werden, zu einem lebendigen Strom im menschlichen Organismus werden; dann stellt sich ihnen gegenüber das innere Weltsystem, die sieben Organe, und zwar deshalb, weil - wie wir schon gesehen haben — der Mensch sonst nicht hinauskommen würde über das pflanzenhafte Dasein. Auf einer weiteren, höheren Stufe ist es notwendig, daß sich entgegenstellen dem Nahrungsstrom die Funktionen dieser sieben Organe. So wirkt also das, was aus der eigentlichen astralischen Natur des Menschen kommt, dem belebten Nahrungsstrom entgegen; der Nahrungsstrom kommt von außen, und das, was die innere Menschennatur ist, wirkt dem entgegen. Zunächst begegnet dem Nahrungsstrom, also der aufgenommenen Außenwelt, der Ätherleib, der die Nahrungsstoffe umwandelt im Verdauungssystem; dann tritt ihm entgegen der Astralleib des Menschen, wandelt die Nahrungsstoffe weiter um und gliedert sie so ein, daß sie immer mehr und mehr der inneren Regsamkeit des Organismus angepaßt werden. In seinem weiteren Verlauf muß der Nahrungsstrom auch erfaßt werden von den Kräften des Ich, des Blutes selber. Das heißt, es muß das Werkzeug des Ich mit seinem Wirken herunterreichen bis dahin, wo der Ernährungsstrom aufgenommen wird. Tut dies das Blut? Bewahrheitet sich das, was wir aus der okkulten Anschauung heraus sagen müssen?
Ja, das Blut wird heruntergetrieben in die Ernährungsorgane ebenso wie in alle anderen Organe. Es macht in den Ernährungsorganen einen Prozeß durch, durch den es erst das vollständige Werkzeug des menschlichen Ich in der physischen Welt sein kann. Wir wissen, daß das Blut als Werkzeug des menschlichen Ich den Übergang durchmachen muß von dem sogenannten roten in blaues Blut. Das Ich wirkt mit seinem Werkzeuge, dem Blut, bis herunter zu den Anfängen der Verdauungs- und Ernährungsprozesse. Da haben wir es nun auch wieder mit einem Widerstand zu tun. Wie geschieht das? Das geschieht, indem das Blut durch das Pfortadersystem in die Leber eintritt und dort aus sozusagen verändertem Blut die Galle bereitet wird und die Galle sich wiederum unmittelbar dem Nahrungsstrom entgegenstellt. Hier in der Galle haben wir eine wunderbare Verbindung der beiden Enden der inneren menschlichen Organisation. Auf der einen Seite stellt der vom Verdauungskanal aufgenommene Nahrungsstrom das äußerste Materielle dar, was in unseren physischen Organismus hineingelangt, auf der anderen Seite steht das Ich, das Edelste, was der Mensch innerhalb der Erdenwelt haben kann, mit seinem Werkzeug, dem Blut. Das Ich stellt eine unmittelbare Verbindung her mit dem äußersten Materiellen, indem es am Ende des Blutprozesses auf dem Umwege über die Leber die Galle bereitet, und in der Galle stemmt sich - in dem umgewandelten, veränderten Blut - dem Nahrungsstrom entgegen das Ich.
Da sehen wir das Ich hinunterwirken bis in das gröbste Materielle und dann wieder hochorganisierte Stoffe wie die Galle aus sich heraussetzen. Und wer diese intimen Vorgänge zwischen Blut, Galle und Ernährungsprozeß verstehen will, der kann gerade in diesen Tatsachen etwas finden, was ihm viele Geheimnisse des menschlichen Organismus klarer erscheinen läßt; und er kann, wenn er diese Prozesse weiterverfolgt, zum Beispiel auch abnorme Prozesse, wie sie sich aus einer Rückstauung der Galle, einer Rückergießung der Galle ins Blut bei der sogenannten Gelbsucht ergeben, richtiger beurteilen und behandeln. Doch das würde heute zu weit führen, wenn wir solche Dinge auch noch ausführten.
So sehen wir, wie in der Tat die sieben Organe sich bis in das Wirken des Ätherleibes hinuntererstrecken und die Einwirkungen des Ich von oben in sich aufgenommen haben. Wir haben also in der Galle etwas, das sich unter dem Einfluß des Ich dem Nahrungsstrom direkt entgegenstellt. Will die Galle auf den Nahrungsstrom wirken, der im Verdauungsprozeß schon ein Lebendiges geworden ist, so muß sie ihm auch als eine lebendige Substanz entgegentreten können. Das geschieht dadurch, daß sie eben aus einem Organ heraus gebildet wird, welches zu den sieben Gliedern des inneren Weltsystems gehört, die das innere des Menschen beleben, so daß damit die Galle als inneres Leben dem von außen kommenden begegnet.
Wie die Galle mit der Leber in Verbindung steht, so finden wir die Leber wiederum in Verbindung mit der Milz. Wenn wir diese Organe Leber, Galle, Milz ins Auge fassen, so müssen wir sagen, diese Organe sind es, welche sich dem Ernährungsstrom unmittelbar entgegensetzen und ihn so umwandeln, daß er fähig wird, zu höheren Stufen der menschlichen Organisation aufzusteigen. Sie haben aber auch diejenigen Organe zu versorgen, die sich nach außen aufschließen, und das tun das Herz, die Lungen, auch schon der Verdauungskanal selber, vor allen Dingen aber die Organe des Kopfes, die Sinnesorgane.
Nun haben wir uns schon früher klar gemacht, daß alles innere Erleben mit Absonderungsprozessen eng verbunden ist. Deswegen haben wir auch diese Absonderungsprozesse besonders betrachtet. Leber, Galle und Milz haben im Sinne jener Vorgänge in der Gesamtorganisation zunächst nichts unmittelbar mit Absonderungsprozessen zu tun, sie sondern zwar Stoffe ab, aber das hat mit der Ernährung zu tun. Sie vermitteln das aufsteigende Leben, das von den niedersten Lebensformen sich hinwendet zum Organ der Bewußtheit, zum Bewußtsein selbst. Indem aber diesen Organen als ein viertes Organ das Herz sich angliedert und das Herz durch den Blutumlauf sich auch nach außen aufschließt, erlangt der Mensch sein IchBewußtsein. Er würde aber nicht in der Lage sein, dieses Ich als das zu erleben, was der Außenwelt gegenübersteht, wenn er nicht dieses nach außen schauende Ich in Beziehung bringen würde zu dem, was er als dumpfes Bewußtsein seines inneren Leibeslebens schon besitzt. Er muß zu den Absonderungsprozessen des inneren Organismus noch einen anderen hinzufügen, welcher ihm auch ein Erleben seines Inneren vermittelt mit dem Ich, das im Blute sein Werkzeug hat.
Zunächst erlebt der Mensch durch die Absonderung der Lymphe sein Innenleben nur in dumpfem Bewußtsein. Dann aber muß auch aus dem Blute abgesondert werden können, und in dieser Absonderung wird der Mensch gewahr, daß er als Eigenwesenheit der Außenwelt gegenübersteht, als inneres Ich. Der Mensch würde aber in seinem Erleben der Außenwelt so gegenüberstehen, daß er sich selbst innerlich verlöre, würde er nicht wissen, daß das dasjenige, was da die Luft atmet und die Ernährungsstoffe von außen aufnimmt und verarbeitet, dasselbe Wesen ist wie das, welches er im Inneren erlebt. Daß der Mensch sich nicht verliert, daß er mit seinem Eigenwesen der Außenwelt gegenübersteht, das ist dadurch möglich, daß er durch die Lungen aus dem umgewandelten Blut absondert die Kohlensäure und durch die Nieren die umgewandelten Stoffe absondert, die aus dem Blut heraus kommen.
Damit sind in ihrer Funktion sowohl die Organe gekennzeichnet, die einen aufsteigenden Prozeß vermitteln, Leber, Galle, Milz, wie auch diejenigen Organe, die einen absteigenden Prozeß vermitteln, Lungen und Nieren. Wir dürfen da aber nicht schematisieren — das geht bei theosophischen Betrachtungen überhaupt nicht —, wir müssen sehen, daß die Lungen, indem sie sich nach außen aufschließen, auch einen aufsteigenden Prozeß vermitteln. Wir sehen also, wie diese sieben wichtigsten Glieder des inneren menschlichen Weltsystems zusammenhängen mit dem inneren Erleben des Menschen und mit dem Sichaufschließen nach außen. Diese sieben Glieder verwandeln auf der einen Seite die Eigenregsamkeit der Nahrungsstoffe in innere Regsamkeit des Organismus und versorgen mit diesen umgewandelten Stoffen den menschlichen Organismus. Sie machen es möglich, daß der Mensch sich wieder nach außen aufschließt. Sie machen es aber auch möglich, daß das, was der Mensch als eine zu starke innere Regsamkeit entwickelt, abgestoßen wird nach außen durch die Absonderungsprozesse der Lungen und Nieren. Durch die Arbeit der Lungen und Nieren haben wir also eine regelmäßige Regulierung der Regsamkeit der menschlichen Organsysteme. Dieses ganze Verhältnis, in dem die menschlichen Organsysteme zueinander stehen, das drückt sich so aus, daß man im Okkultismus in der Tat kein besseres Bild dafür geben konnte, als daß man sagte: Das Herz als Sonne steht im Mittelpunkt und beeinflußt die drei Organe des inneren Weltsystems, die die aufsteigenden Prozesse besorgen, Leber, Galle, Milz. So wie im Makrokosmos die Sonne im Planetensystem steht zu den äußeren Planeten Jupiter, Mars, Saturn, so steht im Mikrokosmos, im menschlichen Organismus, die innere Sonne, das Herz, zu Leber-Jupiter, Galle-Mars, Milz-Saturn. Ich müßte nun nicht wochenlang, sondern monatelang reden, wenn ich Ihnen alle die Gründe auseinandersetzen wollte, warum vor einem genauen und intimen okkulten Beobachten das Verhältnis der Sonne zu den äußeren Planeten unseres Planetensystems wirklich in Parallele gesetzt werden darf zu dem Verhältnis, das im menschlichen Organismus das Herz hat zu dem inneren Weltsystem, zu Leber, Galle und Milz. Es ist in der Tat das äußere Verhältnis absolut so hereingenommen, daß in der Wechselwirkung dieser Organe sich das widerspiegelt, was in der großen Welt des Makrokosmos, in unserem Sonnensystem vor sich geht. Und ebenso ist es berechtigt, davon zu sprechen, daß die Vorgänge, die sich abspielen zwischen der Sonne und den inneren Planeten bis zu unserer Erde herunter, sich widerspiegeln in dem Verhältnis des Herzens zu den Lungen und zu den Nieren. So haben wir in diesem inneren Weltsystem des Menschen etwas, was das äußere Weltsystem widerspiegelt.
Wir haben im Verlaufe der Vorträge auch schon angedeutet, wie in der Tat, wenn wir hellseherisch hinuntertauchen in das eigene Innere, wir aufhören, unsere inneren Organe nur so wahrzunehmen, wie sie sich dem äußeren Anblick des physischen Auges darbieten. Wir müssen hinauskommen über das Phantasiebild, das sich die äußere Anatomie von unseren Organen macht, indem wir aufsteigen zur Betrachtung der wirklichen Gestalt, die diese Organe haben, wenn wir berücksichtigen, daß diese Organe ja Kraftsysteme sind. Durch die äußere Anatomie kann gar nicht das wirkliche Sein dieser Organe ergründet werden, denn sie sieht ja in ihnen nur die hineingestopften umgewandelten Nahrungsstoffe. Und gerade dadurch, daß die äußere Wissenschaft nur diese Anschauung gelten lassen will, kann sie nicht die inneren Kraftsysteme, welche den Organen zugrundeliegen, erkennen. Für denjenigen aber, der in der Lage ist, das, was diesen Organen als Kraftsysteme zugrundeliegt, durch hellseherische Beobachtung zu schauen, der sieht, wie berechtigt es ist, die Organe mit den Namen der Planeten zu benennen, weil er erkennt, wie das Verhältnis zwischen den Planeten unseres äußeren Weltsystems sich wiederholt in unserem inneren Organsystem.
Nun haben wir gestern gesagt, daß die Organe eine zu starke innere Regsamkeit entwickeln können. Jedes einzelne der Organe kann eine zu starke Regsamkeit entwickeln, und diese Unregelmäßigkeit kann sich so ausdrücken, daß sie sich auf den ganzen Organismus auswirkt. Nun habe ich schon gestern darauf hingedeutet, daß wenn durch solche zu starken inneren Regsamkeiten etwas wie ein eigensinniges Eigenleben in den inneren Organen auftritt, es notwendig ist, dasjenige entgegenzusetzen, was diese inneren Regsamkeiten dämpft. Das heißt, wenn die inneren Organe zu stark umsetzen, zu stark umwandeln die äußeren Regsamkeiten der Nahrungsstoffe, wenn sie ein zu starkes inneres Verwandlungsprodukt liefern, dann müssen wir ihnen etwas von außen entgegensetzen, das sie eindämmt, das die übermäßige innere Regsamkeit dämpft.
Wie kann das geschehen? Wenn wir ein Organ des inneren Systems treffen wollen, das eine zu starke innere Regsamkeit entwickelt, so müssen wir in der Außenwelt dasjenige suchen, welches die entgegengesetzte Regsamkeit hat, und dies dem Organismus zuführen, um dadurch die zu starke Regsamkeit des Organs bekämpfen zu können. Das heißt, wir müssen versuchen, jene äußeren Regsamkeiten aufzufinden, welche den Regsamkeiten der einzelnen Organe entsprechen. Im Mittelalter haben die Menschen noch vieles davon gewußt, wie die Stoffe der Umwelt, also äußere Substanzen, der übertriebenen Regsamkeit der Organe entgegenwirken können. Für den heutigen Menschen, dem solche Dinge oft nur aus verballhornten Schriften des Mittelalters entgegentreten, in denen er nichts als bunten Aberglauben sehen kann, hört sich das ganz sonderbar an. Aber von der okkulten Wissenschaft ist das Entsprechen der Organe des inneren Weltsystems mit gewissen äußeren Substanzen durch Jahrtausende sorgfältig, tief und gründlich untersucht worden, und unzählige Beobachtungen, die mit dem hellsichtigen Auge gemacht worden sind, haben erwiesen, daß zum Beispiel dem übermäßig tätigen inneren Jupiter, der Leber, Einhalt geboten werden kann durch die Metallsubstanz des Zinns. Die übermäßige innere Regsamkeit der Galle bekämpfen wir durch dasjenige, was in der Metallsubstanz des Eisens zum Ausdruck kommt. Das ist gar nicht zu verwundern, denn Eisen ist das einzige Metall, das wir in unserem Blut haben müssen als wesentlichen Bestandteil für das Werkzeug des Ich, und wir haben ja gesehen, daß in der Galle gerade dasjenige Organ vorliegt, welches vermittelt die Verbindung von dem Ich mit dem dichtesten Materiellen, das dem Menschen eingelagert wird, dem Nahrungsstrom. Ebenso können wir sagen, daß die Milz ihre äußere Entsprechung hat in dem Metall Blei. Dem Herzen - Sonne - entspricht das Gold. Den Lungen — Merkur -, das sagt der Name selbst, entspricht das Quecksilber und den Nieren das Metall Kupfer, also die Venus. (Es wird an die Tafel geschrieben:)
Saturn Milz Blei
Jupiter Leber Zinn
Mars Galle Eisen
Sonne Herz Gold
Merkur Lungen Quecksilber
Venus Nieren Kupfer
Nun müssen wir, wenn wir mit den Regsamkeiten, die in diesen Metallen sich finden, die überhandnehmenden Regsamkeiten des inneren Organismus bekämpfen wollen, uns darüber klar sein, daß alles im Organismus mehr oder weniger zusammenhängt und daß ja die einzelnen Organsysteme parallel miteinander gebildet werden, daß also nicht etwa der Mensch zuerst als kopfloses Wesen entstanden ist; sondern es bilden sich natürlich diejenigen Organe, welche in Zusammenhang stehen mit dem oberen Blutkreislauf, das GehirnRückenmarksystem, gleichzeitig mit den Organen des inneren Weltsystems.
Wie wir gesehen haben, daß es einen nach oben gehenden und einen nach unten gehenden Blutkreislauf gibt, so haben wir auch ein Hinaufwirken des Lymphprozesses, dem wir ein dumpfes Bewußtsein zuerkannt haben, zu den oberen Partien des menschlichen Organismus. Und es besteht nun die Tatsache, daß das, was dem Blutstrom oben eingegliedert ist, in gewisser Weise demjenigen entspricht, was dem unteren Blutstrom eingegliedert ist, und wir können sehen, daß die vorher genannten Metalle auch eine Verwandtschaft haben zu dem oberen Organsystem des Menschen. Sie wissen, daß die Lunge sich aufschließt nach außen zum Kehlkopf, der ein Organ des oberen menschlichen Organismus ist. Wie wir für die Galle im unteren Organsystem einen Zusammenhang zu sehen haben mit dem Eisen, so können wir das Eisen im oberen Organsystem in Verbindung bringen mit dem Kehlkopf. Diese Dinge sind natürlich schwierig, aber ich möchte doch einiges davon andeuten. So wie wir einen Zusammenhang vermerkt haben zwischen Galle und Kehlkopf in bezug auf das Eisen, so gibt es auch in bezug auf das Zinn — Jupiter — eine gewisse Entsprechung zwischen den oberen Teiles unseres Kopfes mit allem, was als Vorderhaupt und als Gehirnbildung dazugehört, und der Leber; und in bezug auf das Blei — Saturn - eine Entsprechung zwischen Hinterhaupt und Milz.
Auf diese Weise haben wir unsere Betrachtungen erstrecken können auf alles das, was dem menschlichen Blutkreislauf eingegliedert ist in den sieben Gliedern des inneren Weltsystems, und darauf, wie es in Zusammenhang steht mit der äußeren Welt. Für das normale wie für das abnorme Leben können wir diese Entsprechungen in Betracht ziehen. In diesen Entsprechungen der Metalle zu den inneren Organen haben wir eine höchst interessante Tatsache. Und wenn einmal nicht in chaotischer Weise, sondern systematisch dasjenige untersucht und zusammengestellt würde, was unsere therapeutischen Bücher an vielfachen Angaben enthalten, dann würden diese Entsprechungen sich schon ganz von selbst nachweisen lassen aus den äußeren Tatsachen. Und wenn heute solche Ausführungen noch als Phantasiegebilde betrachtet werden, so kann sich der Okkultist dazu ganz ruhig verhalten, denn er weiß, daß die Zeit kommen muß, wo die äußeren Tatsachen seine Behauptungen bestätigen werden.
Nun dürfen wir nicht denken, daß wir zum Beispiel bei einer Nierenkrankheit ohne weiteres gewöhnliches Kupfer geben müßten; das wäre natürlich ein Fehler. Wenn wir dem Organismus metallische Substanzen zuführen wollen, so müssen wir sie erhitzen, so daß sie in eine Art Metalldampf übergehen. Dabei entwickelt sich etwas wie dampfförmige Körperchen, und in dieser Form kann die Metallität auf die inneren Organe wirken. Nehmen wir jetzt das Blutsystem, so wäre bei Erkrankungen mit Metallen nichts geholfen. Wir haben schon darauf hingewiesen, daß im Blutsystem eine Art Salzablagerung vor sich geht. Und geradeso nun, wie auf die inneren Organe das Metallische wirkt, so wirkt auf das Blutsystem das Salzartige. Will man nun das Blutsystem durch äußere Mittel beeinflussen, so muß man ihm Salzartiges zuführen. Dies kann geschehen durch Einatmen von salzhaltiger Luft, durch Salzbäder oder dergleichen. Wir können aber auch von der anderen Seite, durch den Verdauungsprozeß, Salze oder Salzbildendes zuführen, so daß wir in der Lage sind, von zwei Seiten her den Prozeß der Salzbildung, der Salzeinlagerung hervorzurufen.
Wenn Sie sich erinnern an das, was ich gestern ausgeführt habe über die physischen Wirkungen der inneren geistig-seelischen Prozesse, so werden Sie sich leicht denken können, daß alles dasjenige, was im Gegensatz zu den im Metallischen wirkenden Vorgängen steht, die physische Wirkung der Gefühlsprozesse ist, denn diese Gefühlsprozesse stehen in engstem Zusammenhang mit den Quellungsprozessen im Blut, die aber aufgehalten werden können durch Zuführung äußerer metallischer Stoffe, welche die entgegengesetzte Regsamkeit zeigen. Wenn zum Beispiel die Verdauungstätigkeit überhand nimmt und dort, wo der Ernährungsstrom vom Ätherleib ergriffen wird, eine eigene Regsamkeit entwickelt, so können wir dieser entgegenwirken durch geeignete Salzzuführung; denn, übertreibt der Ätherleib diesen Prozeß des Ergreifens des Ernährungsstromes, so bedeutet das ein zu starkes Aufnehmen des Salzes. Er muß abgedämpft werden durch die Zufuhr der äußeren Regsamkeit eines Salzes.
Dann haben wir Prozesse, welche sich äußerlich abspielen als Verbrennungs- oder Oxydationsprozesse; das sind solche Prozesse, wo sich etwas mit dem Sauerstoff der Luft verbindet. Alle diejenigen Stoffe, die sich leicht mit dem Sauerstoff der Luft verbinden, durchstrahlen, wenn sie in den Organismus aufgenommen werden, mit ihrer Regsamkeit den Organismus am weitesten. Während Salze, wenn wir sie dem Organismus zuführen, nur bis zu einem mäßigen Grade auf den Organismus wirken, kann die Metallität bis in das innere Weltsystem hinein wirken. Und in der Luft, also in den Stoffen, die sich leicht mit dem Sauerstoff der Luft verbinden, haben wir etwas, was, wenn es in den Körper aufgenommen wird, den ganzen Organismus durchstrahlt bis in das Blutsystem hinein. So werden wir es begreiflich finden können, daß wir durch solche Vorgänge, die eine zu starke innere Regsamkeit in der Wärmeentwickelung bilden, die ja der äußere Ausdruck der Willensimpulse ist, in unserem ganzen Organismus uns beeinflußt fühlen. Bei den organischen Rückwirkungen des Denkerischen ist das nicht so; wenn wir auf diese unser Augenmerk richten, fühlen wir, daß diese Wirkungen nur in gewissen Organen sich abspielen. Sie sehen daraus, wie außerordentlich kompliziert der ganze Apparat des menschlichen Organismus ist und wie kompliziert sein Verhältnis zur Außenwelt ist.
So haben wir jetzt gezeigt, wie dem menschlichen Organismus mit seiner eigenen inneren Regsamkeit entgegengesetzt werden kann die äußere unorganische, unbelebte Natur, und wie durch Salze und durch verdampfte Metallität auf den Organismus eingewirkt werden kann. Aber wir haben auch die Möglichkeit, aus anderen Bereichen der Natur auf den Menschen einzuwirken. Wir können dem menschlichen Organismus ebenso das entgegensetzen, was die regsamen Kräfte in der Pflanzenwelt sind. Wenn wir ein pflanzliches Heilmittel einfach als Nahrung aufnehmen, so würden wir dadurch nicht viel erreichen, weil, wie wir gesehen haben, die inneren Organe dafür sorgen, daß den eingenommenen Stoffen ihre eigene Regsamkeit genommen wird. Soll also die Pflanze in den menschlichen Organismus so aufgenommen werden, daß sie auch in ihrer Eigenschaft als Pflanze weiterwirkt, so kann das nicht geschehen, wenn wir sie als Nahrung zu uns nehmen. Dieses Pflanzliche kann auf das Ich nicht einwirken, denn die Pflanze hat als höchstes Glied nur einen Ätherleib. Das Pflanzliche wird also einfach aufgenommen, da wo der Nahrungsstrom eingefangen wird vom Ätherleib, so daß das Pflanzliche als Heilmittel noch nicht im Verdauungskanal in Betracht kommen kann, sondern erst in jenen Organen, in die neben dem Ätherleib auch schon der astralische Leib des Menschen hineinwirkt. Aus diesem Grunde beginnt das Pflanzliche erst zu wirken auf das innere Weltsysteem und auf das sympathische Nervensystem und das Lymphsystem. Nicht mehr erstreckt sich die Wirkung des Pflanzlichen dahin, wo der Mensch durch das Blut sich wiederum aufschließt der äußeren Welt. Die Pflanze ist zugeordnet dem mittleren Teil des menschlichen Organismus, so daß alles, was in dem Pflanzlichen gesucht werden kann an Regsamkeit, nur wirken kann auf alles das, was zu dem inneren Weltsystem gehört und auf die entsprechenden Organe des Kopfes und des oberen Teiles des Organismus. Wenn die Tätigkeiten, die Funktionen dieser Organe gestört sind, wenn sie in einer abnormen Weise wirken, dann kommt zur Bekämpfung die Einwirkung des Pflanzenhaften in Betracht.
Wir haben also gesprochen über die Wirkungen von Metallen, Salzen und Pflanzen. Es ist nun nicht angezeigt, in unseren Betrachtungen noch auf weitere Arten der Bekämpfung von Unregelmäßigkeiten oder Störungen im menschlichen Organismus einzugehen, nicht so sehr deshalb, weil die Zeit zu kurz ist, sondern in der Hauptsache, weil sich Theosophen am besten fernhalten von all den Gebieten, die heute in den Streit der Parteien hineingezogen werden. Das, was bis jetzt aufgezählt worden ist, gehört nicht dem Streit der Parteien an; man kann es einfach aufnehmen, und dann wird man schon die Richtigkeit einsehen; oder aber die Menschen halten es eben für reinen Unsinn, für Phantasterei. Das macht nichts. Denn da müßte man als Theosoph überhaupt schweigen, wenn man alle Dinge nicht sagen wollte, die von den Menschen als Unsinn angesehen werden. Wenn wir aber die Einwirkungen tierischer Substanzen auf den Menschen untersuchen wollten, so würden wir in den Streit der Parteien hineinkommen und man könnte dann meinen, Theosophie wolle sich einmischen in diesen Streit, der sich abspielt zwischen den Vorkämpfern und den Bekämpfern der Heilmethoden auf dem Gebiete des Tierischen. Und es kann niemals Aufgabe des Theosophen sein, sich in solche fanatischen Streitigkeiten zu mischen, denn dann würden wir Gefahr laufen, den objektiven allgemein-menschlichen Standpunkt zu verlassen.
Das eine aber haben wir gesehen, wenn auch die Andeutungen alle nur skizzenhaft waren, daß dieser menschliche Organismus ein kompliziertes System ist von einzelnen Organen, die auf verschiedenen Stufen der Entwickelung stehen und die in der mannigfaltigsten Weise unter sich und mit dem Gesamtorganismus zusammenhängen. Was als physischer Organismus des Menschen sichtbar ist, was wir mit Augen sehen, mit Händen greifen können, ist nur ein Teil der menschlichen Organisation; das Übersinnliche aber, das da hineinwirkt, das nehmen wir nicht in solcher Weise sinnlich wahr, das erschließt sich erst dem geistigen Auge des Sehers. Wir dürfen also nicht sagen, daß alle Organe sich gleichmäßig ausgebildet haben, sondern es hat sich gezeigt, daß wir den menschlichen Organismus so anzusehen haben, daß darin Älteres und Jüngeres zu erkennen ist. Wir haben ja schon hervorgehoben, daß wir zum Beispiel das Gehirn als ein älteres, höher entwickeltes Organ anzusehen haben als das Rückenmark und daß das Gehirn früher gewissermaßen auf der Stufe des Rückenmarks gewesen ist. In analoger Weise können wir das Verdauungs- und das Blutsystem betrachten gegenüber dem Lymphsystem. Hier haben wir das Lymphsystem vergleichsweise auf die Stufe des Rückenmarks zu stellen, es ist also das jüngere, während das komplizierte Verdauungsund das Blutsystem bereits in vielfacher Weise umgewandelt und älter sind als das Lymphsystem, das sich nicht nach außen aufschließt und seine Stoffproduktion nur nach innen in die Gewebe absondert. Das ist ein sehr wichtiger Gesichtspunkt. Wir haben also unser heutiges Lymphsystem anzusehen als etwas, das, wenn es nicht eingelagert wäre den anderen Systemen, bei fortschreitender Entwickelung zu einem Verdauungs- und Blutsystem würde.
Ein einfacheres Vermittlungssystem des Bewußtseins haben wir im Lymphsystem; das, was komplizierter ist, haben wir im VerdauungsBlutsystem. Wir haben also im menschlichen Organismus Organe zu suchen, welche aus Organsystemen hervorgegangen sind, die früher andere Aufgaben hatten. Die Mitteilungen, die hier darüber gemacht worden sind, würden auch für die äußere Wissenschaft sehr klar nachzuweisen sein, wenn man sich damit vertraut machen wollte. Alles, was über die Umwandlung der Organe gesagt worden ist, läßt sich nachweisen durch embryologische Untersuchungen. Bei einem jeglichen Lebewesen ist es so, daß dasjenige, was im Laufe der Entwickelung später erscheint, in der Keimanlage bereits vorgebildet ist. Wenn wir vom ausgebildeten Menschenorganismus bis zum befruchteten Keim zurückgehen, so könnten wir mit geeigneten Methoden die komplizierten Organsysteme in ihrer allerersten Anlage bereits angedeutet finden, und zwar so, daß sie selbst in der allerersten Anlage schon zeigen, wie sie eigentlich zueinander stehen.
Wenn Sie sich einmal das anschauen, was wir als äußere Umhüllung, als Begrenzung des Menschen vor uns haben in seiner Haut, und dann weiterhin das, was zu den ihr eingelagerten Sinnesorganen führt, so werden Sie sich sagen können, daß alles das, was da in dieser äußersten Begrenzung des Menschen vorhanden ist, schon umgewandelt sein muß aus einem Anderen. Denn es ist schon ein sehr kompliziertes System, dem auch ein Gehirn angehört; und ein Gehirn ohne langwierige Vorbereitung sich zu denken ist unmöglich. Wir müssen uns also denken, daß die äußere Umhüllung des Menschen ein Umwandlungsprodukt ist, ähnlich wie wir ja das Gehirn als ein umgewandeltes Rückenmark bezeichnet haben und das Ernährungsund Blutsystem als ein Umwandlungsprodukt des Lymphsystems. Während nun das Rückenmark und das Lymphsystem auf früheren Stufen eine aufsteigende Tendenz zeigten, müssen wir von dem heutigen Rückenmark- und Lymphsystem sagen, daß sie in absteigender Entwickelung begriffen sind. Man würde auch zeigen können, daß das Blut in seiner heutigen Konfiguration ein doppeltes Umwandlungsprodukt ist. Dadurch, daß sich das Verdauungs- und Blutsystem nach außen aufschließt, wird es zu einem umgewandelten Lymphsystem. Wäre das Verdauungssystem mit seinen Bewegungen nur nach innen hin entwickelt, wäre es ganz nach innen abgeschlossen, hätten wir in ihm eine ähnliche Tätigkeit wie in der heutigen Lymphtätigkeit. Bei ihr wird nur dasjenige aufgenommen, was über die Gewebe zugeführt wird.

So ist auf der einen Seite in der äußeren Umgrenzung des Menschen, im Hautsystem, ein Umgewandeltes zu sehen aus einem anderen System, dem Blutsystem, das ich hier so zeichnen will, und auch in dem Verdauungssystem haben wir die Umwandlung aus einem anderen System zu sehen, das heute in absteigender Entwickelung ist. Wir müssen nun festzustellen suchen, ob wir diese auf- und absteigende Natur von Organsystemen schon angedeutet finden in der Keimanlage. Und in der Tat zeigt sich, daß wir den Gesamtorganismus in der Keimanlage angedeutet finden - ich will es schematisch zeichnen - in den vier übereinanderliegenden Keimblättern, die man nennt: das äußere Keimblatt — Ektoderm -, das innere Keimblatt — Entoderm — und das Mesoderm - das äußere und das innere mittlere Keimblatt.

Dabei haben wir im Sinne unserer Anschauung über die Entwickelung das äußere Keimblatt, das Ektoderm, das man in der heutigen Anatomie auch das Hautsinnesblatt nennt, anzusehen als ein Umwandlungsprodukt, das seine erste Anlage zeigt in dem äußeren Mittelblatt, dem äußeren Mesoderm. In diesem haben wir dasjenige als Keimanlage vor uns, was auf einer höheren Stufe in dem Hautsinnesblatt uns vor Augen tritt. Und in dem inneren Mittelblatt, dem inneren Mesoderm, haben wir die jüngere Bildung dessen vor uns, was sich später im Entoderm, im Darmdrüsenblatt, zeigt.
Wenn wir den menschlichen Keim in seiner Entwickelung betrachten, so haben wir die erste Anlage des Menschen in den beiden mittleren Keimblättern angedeutet, in den Mesodermen; die beiden anderen Keimblätter, Ektoderm und Entoderm, sind bereits umgewandelt. Die beiden Mittelblätter sind also die, welche den ursprünglichen Zustand darstellen, während Ektoderm und Entoderm die höhere Entwickelung zeigen.
Nun wissen wir, daß die entwickelungsfähige Keimanlage des Menschen zusammenfließt aus zwei Anlagen, aus der weiblichen und der männlichen Keimanlage, und daß eine Neuentwickelung nur entstehen kann durch das lebendige Zusammenwirken dieser beiden Anlagen. In den beiden Keimanlagen müssen also getrennt enthalten sein alle die Prozesse, die nur vereint die Keimanlage für den menschlichen Organismus bilden.
Was zeigt uns nun der Okkultismus in bezug auf die hierbei obwaltenden Verhältnisse? Er zeigt uns, daß unter den heutigen physischen Bedingungen der weibliche Keim [Entoderm] nur imstande ist, eine solche menschliche Körperanlage zu produzieren, die, wenn sie sich einzeln entwickeln wollte, nicht das entwickeln könnte, was wir das Formprinzip nennen, das zuletzt zur Einlagerung des Knochensystems führt, das dem Menschen seine Festigkeit gibt; und auch das Hauptsinnessystem würde nicht durch den weiblichen Keim geliefert werden können. Es ist der weibliche Keim so angelegt, daß man fast sagen könnte, das, was da entsteht, würde zu gut sein für die Welt, so wie sie heute besteht, denn es sind nicht alle Prozesse in der äußeren physischen Welt vorhanden, welche einem solchen Organismus notwendig wären. Dieser weibliche Menschenorganismus könnte sozusagen nicht bis zu jener «Vererdigung» fortschreiten, wie sie in dem eingelagerten Knochensystem zum Ausdruck kommt, und er hätte nicht die Möglichkeit, verbunden zu sein mit der Außenwelt durch die Sinne. Er müßte in den äußeren Bedingungen eine Stütze finden, um sein weicheres inneres Material, das er anstelle des festen Knochengerüstes hätte, auszugleichen; er könnte sich nicht nach außen aufschließen, sondern würde in seinem inneren Leben abgeschlossen bleiben. Das ist der weibliche Anteil an der Keimanlage; er würde über das Ziel dessen hinausschießen, was heute in unserem irdischen Dasein möglich ist, einfach weil in den heutigen physischen Erdenverhältnissen nicht die Bedingungen gegeben sind, welche ein solcher verfeinerter Organismus nötig hätte, der so wenig zur Vererdigung und zum Aufschließen nach außen angelegt ist. Ein solcher Organismus wäre unter den heutigen irdischen Verhältnissen von vornherein zum Tode bestimmt. So ist wirklich der menschlichen Keimanlage, gerade durch die Tendenz, daß der Mensch in seiner Fortentwickelung zu weit kommen könnte, schon die Ursache dafür eingeprägt, daß der Mensch zum Tode bestimmt ist.
Der andere Anteil der Keimanlage, der männliche [Ektoderm], ist in der genau umgekehrten Lage. Wenn die männliche Keimanlage allein sich entwickeln würde, so würde dies zu mächtiger Entfaltung dessen führen, was sich kundgibt in dem Sichaufschließen nach außen im Hautsinnessystem, und dessen, was zur Verfestigung im Knochensystem führt, also nach der anderen Seite über das Ziel hinausschießen. Eine solche Einseitigkeit würde ebensowenig eine lebensfähige Keimanlage hervorbringen können wie der weibliche Keim für sich, denn der Organismus, den die männliche Keimanlage entwickeln würde, würde so starke Kräfte entfalten, daß er sich selbst zerstören und zugrunde gehen müßte unter den Verhältnissen, wie sie heute auf der Erde vorhanden sind, das heißt, er würde unter diesen heutigen Verhältnissen auf der Erde als Organismus nicht bestehen können. Der männliche Keim kann daher nur dann zu einem lebensfähigen Ausdruck kommen, wenn er mit der weiblichen Keimanlage zusammenwirkt. Nur dadurch, daß die beiden Keimanlagen sich ausgleichen, daß dasjenige, was in der weiblichen Keimanlage zum Tode bestimmt ist, sich ausgleicht mit dem der männlichen Keimanlage durch den Befruchtungsprozeß, ist eine lebendige Gesamtanlage des Menschen möglich. Was an Kräften zusammengedrängt vorhanden ist in der männlichen Keimanlage, das würde, wenn es für sich allein auswachsen würde, unendlich unter das Irdische hinunterführen, es würde zu einer viel größeren Verhärtung des Knochensystems führen, zu einem weit größeren Sichaufschließen und Aufgehen in der Außenwelt. Diese beiden organischen Keime müssen sich schon in ihrer allerersten Entstehung zu weiterer Entwickelung zusammenfinden, denn einzeln ist jede von ihnen zum Tode bestimmt. Nur die lebendige Wechselwirkung dessen, was nach beiden Seiten hin das Überhandnehmen des einen über das andere verhindert, ergibt die für das Erdendasein des Menschen mögliche Keimanlage.
So sehen wir, wenn es auch nur in skizzenhafter Art gezeigt werden konnte, daß wir die geistigen Tatsachen bis dahin zurückverfolgen können, wo der Mensch seinesgleichen hervorbringt. Wir würden dies natürlich noch viel ausführlicher darstellen können, aber in einem kurzen Zyklus läßt sich natürlich nicht alles sagen. Wenn wir noch tiefer hineinleuchten würden, so würden wir sehen, wie sich bewahrheitet, daß auch das Minuziöseste auf geistige Tatsachen zurückgeht, bis hin zu dem, was hier über die übersinnlichen Kraftsysteme gesagt worden ist, die ihren äußeren Ausdruck finden in den Organsystemen, die der Mensch entwickelt, damit sein Geschlecht über die Erde hin lebt.
Wir haben gesehen, daß die Erde als Ergebnis des dichtesten «Vererdigungsprozesses» in uns hervorgebracht hat das Knochensystem, und als das am wenigsten verdichtete, als das regsamste, das Blutsystem. Und es soll nur noch kurz hinzugefügt werden, daß alles, was vorgeht im irdisch-physischen Menschenorganismus, hinaufdringt bis zu den Vorgängen, die sich im Blute abspielen; das sind die Erwärmungsvorgänge. Wir haben in diesen Erwärmungsvorgängen des Blutes den unmittelbaren Ausdruck des Ich und damit das oberste Niveau zu sehen, und darunter sich abspielend die anderen Prozesse des menschlichen Organismus. Der Erwärmungsprozeß ist also das Höchste, in diesen greift unsere Ich-Seelentätigkeit unmittelbar ein. Deshalb fühlen wir auch etwas wie eine Verwandlung unserer Ich-Seelentätigkeit in ein inneres Warmwerden, das bis zum physischen Warmwerden im Blutprozeß gehen kann. Wir sehen also, wie das Geistig-Seelische von oben nach unten gehend durch den Erwärmungsprozeß eingreift in das Organische, das Physiologische, und wir könnten noch an vielen anderen Tatsachen zeigen, wie das Geistig-Seelische sich in Erwärmungsprozessen berührt mit dem Organischen. Erwärmungsprozesse haben wir auch durch die Vorgänge in den Ernährungsorganen. Durch die Tätigkeit der komplizierten Apparate des Ernährungssystems finden die mannigfaltigsten Verwandlungen statt, durch die es im physischen Organismus zu Erwärmungsprozessen kommt. Diese erstrecken sich von unten nach oben. Es reicht also im Erwärmungsprozeß der physische Organismus des Menschen bis hinauf ins Geistig-Seelische. Hören damit die Umwandlungen auf? Oder gehen sie weiter? Was dann folgt, kann nur angedeutet werden; es muß zunächst dem weiteren Nachdenken und namentlich Nachfühlen eines jeden Zuhörers überlassen werden. Wenn wir diese Umwandlungen mit Gefühlen wirklicher Ehrfurcht für den menschlichen Organismus betrachten können, so lernen wir einsehen, daß Physiologie nicht eine trockene Wissenschaft zu sein braucht, sondern eine Quelle höchster menschlicher Erkenntnis sein kann.
Was der Organismus produziert an innerer Wärme in unserem Blut, an Wärme, die er uns durch die gesamten inneren Prozesse zuleitet, das zeigt, daß wir in den Erwärmungsvorgängen etwas zu sehen haben wie eine Blüte aller anderen Prozesse im Organismus. Die innere Wärme des Organismus dringt bis hinauf in das GeistigSeelische und kann sich bis in Geistig-Seelisches hinein verwandeln. Das ist das Höchste, das Schönste, das durch die Kraft des Menschenleibes Physisches umgewandelt werden kann in Geistig-Seelisches. Wenn alles, was im menschlichen irdischen Organismus veranlagt ist, zu Wärme geworden ist und die Wärme vom Menschen in der rechten Weise umgewandelt wird, dann entsteht aus der inneren Wärme Mitgefühl und Interesse für andere Wesen. Wenn wir durch alle Prozesse des menschlichen Organismus hindurch aufsteigen bis zum obersten Niveau, den Erwärmungsprozessen, so schreiten wir gleichsam durch das Tor des menschlichen Organismus, das gebildet wird durch die Wärmeprozesse, hinauf bis dahin, wo die Wärme des Blutes verwertet wird durch das, was die Seele daraus macht. Durch lebendiges Interesse für alle Wesen, durch Mitgefühl für alles, was um uns herum ist, erweitern wir, indem unser physisches Leben uns bis zur Wärme hinaufführt, unser Geistig-Seelisches über das gesamte irdische Dasein, und wir machen uns eins mit dem gesamten Dasein. Es ist eine wunderbare Tatsache, daß die Weltwesenheit den Umweg gemacht hat durch unseren physischen Organismus, um uns zuletzt die innere Wärme zu geben, die wir Menschen in der Erdenmission berufen sind umzuwandeln durch unser Ich in lebendiges Mitfühlen mit allen Wesen.
Wärme wird in Mitgefühl umgewandelt in der Erdenmission!
Die Tätigkeit des menschlichen Organismus benützen wir sozusagen als Heizwärme für den Geist. Das ist der Sinn der Erdenmission, daß der Mensch als physischer Organismus dem Erdenorganismus so eingelagert ist, daß alle physischen Prozesse zuletzt ihre Vollendung, ihre Krone in der Blutwärme finden, und daß der Mensch als Mikrokosmos in Erfüllung seiner Bestimmung diese innere Wärme wiederum umwandelt, um sie auszuströmen als lebendiges Mitgefühl und Liebe für alles, was uns umgibt. Durch alles, was wir aus lebendigem Interesse in unsere Seele aufnehmen, wird unser Seelenleben erweitert. Und wenn wir dann durch viele Inkarnationen gegangen sind, in denen wir alle Wärme, die uns gegeben worden ist, verwertet haben, dann wird die Erde ihr Ziel, das innerhalb der Erdenmission zu erfüllen war, erreicht haben, dann wird sie als Erdenleichnam hinuntersinken und dem Verfall überliefert sein. Und aufsteigen wird die Gesamtheit aller jener Menschenseelen, die die physische Wärme umgewandelt haben in Herzenswärme. Wie die einzelne Seele, wenn der Mensch durch die Pforte des Todes gegangen ist, aufsteigt zu einer geistigen Welt, nachdem der physische Leichnam den Erdenkräften übergeben wurde, so wird einstmals der Erdenleichnam den Weltenkräften übergeben werden, und die einzelnen Menschenseelen werden zu neuen Daseinsstufen fortschreiten. Nichts in der Welt geht verloren. Was die Menschenseelen als Früchte auf der Erde errungen haben, das wird durch die Menschenseelen in Ewigkeiten hinübergetragen.
So gestattet uns die Geisteswissenschaft, auch die physiologischen Prozesse im menschlichen Organismus anzuknüpfen an unsere Ewigkeitsbestimmung. Wenn uns die Geisteswissenschaft (Theosophie) nicht bloße Theorie, nicht bloß abstrakte Erkenntnis ist, sondern wenn wir sie so betrachten, daß sie uns zeigt: wir stehen als Menschen nicht nur auf der Erde, sondern wir gehören zum gesamten Weltensystem —, und wenn wir lernen, so über die Bestimmung des Menschen zu denken, daß er die Kräfte von der Erde nimmt, um in die Ewigkeit hineinzuwirken, dann nehmen wir durch Geisteswissenschaft (I'heosophie) das auf, was durch sie errungen werden muß. Und wenn die Menschen, die dieses hohe Ideal ahnen oder erkennen, sich brüderlich zusammenfinden und übereinstimmen in ihrem Streben, das heißt, wenn wir erkennen, daß in uns selbst die Keime zur Weiterentwickelung enthalten sind, die fruchtbar werden können für die weitere Erden- und Menschheitsentwickelung, dann können wir in aller Bescheidenheit das Gefühl haben, daß wir als Theosophen (Anthroposophen) durch die Entwickelung unserer eigenen Kräfte mitwirken können an der Erfüllung der Erdenmission.
Wir sind hier zusammengekommen und werden nun wieder hinausgehen, um draußen zu leben und vielleicht manches von dem, was ja nur skizzenhaft hier als Anregung hat gegeben werden können, mit hinaus zu nehmen und weiter zur Entfaltung zu bringen. Aber auch wenn wir in der Welt zerstreut sind, so wollen wir in lebendigen Gedanken und Empfindungen und mit unserem ganzen Wollen miteinander harmonisch zusammenwirken. In diesem Geiste wollen wir voneinander scheiden, in diesem Geiste wollen wir uns auch wiederfinden, wenn dazu Gelegenheit sein wird.
Eighth Lecture
In this final lecture today, it will be my task to combine the observations of the last few days on occult physiology, which have attempted to describe some aspects of the processes of human organization, albeit in a rather sketchy manner, into a kind of overall picture, which can only be sketchy, enabling us to gain an insight into the living life and workings of the human organism. The best way to do this is to start again from the most basic level, from the interrelationship between the human organism and the external world, our physical earth, in the absorption of nutrients.
After being absorbed, these nutrients are transformed in the most diverse ways and gradually changed by the various organ functions so that they can be directed to the individual members of the human organism, to the individual systems of the human physical being. It is not difficult to see that everything that becomes of the nutrients in the human organism actually makes the human being, as he stands before us in the physical world, a physical human being. There is, of course, a certain difficulty in understanding this. However, if we take the principles we have adhered to so far seriously and really apply supersensible knowledge to the observation of the human being, we must say that it is only the nutrients that are substantially absorbed from the external world into the human organism. All other influences acting upon the human being must be thought of as supersensible, invisible forces. If you imagine for a moment that everything that fills the human organism, originating from nutrients, is removed, then in physical terms you are left with even less — forgive the trivial expression — much less than an empty sack, namely nothing at all. For even what is present in the skin, the covering of the physical organism, is only present because appropriately processed nutrients have been transported to the relevant parts. If you take away the nutrients and what becomes of them, you are left with the human organism as a supernatural system of forces that distributes the assimilated nutrients in all directions. If you really take this idea, as it has now been expressed, to heart, you will say to yourself: But there is actually one prerequisite before anything, even the smallest thing, can be absorbed from the nutrients, because these substances cannot be transported from the outside world into any being so that what happens in the human organism can take place within it. From the very first intake of food, the human being must be able to counteract the physical nutrients with an inner force that originates from the supersensible world, and this inner force system must already be contained within the human being as such. In occultism, we call that which is initially opposed to the actual physical filling materials of the human being, which is already to be thought of as supersensible, the human form in the most comprehensive sense. If we think of the lowest limit of the human organization, we must imagine that physical matter and the supersensible form stand opposite each other, which, as a force system born out of the supersensible worlds, is destined to take up matter—not like a physical sack or bellows, but as something superphysical, supersensible—and to form that which makes the human being appear physically and sensually in the first place. It is only through the assimilation of nourishment into this supersensible form that the otherwise purely supersensible human organism becomes a physical-sensible organism that can be seen with the eyes and touched with the hands. What is opposed to physical matter is called “form” because such a law is actually at work in all of nature, an exactly identical law that is called the “principle of form” everywhere. When we look at the external world, we find that the principle of form is at work everywhere, down to the crystal. The substances that enter the crystal must, in order to become what the crystal represents, be captured, as it were, by the principle of form, and this, with the help of the substances, makes the crystal what it is. Take, for example, table salt, sodium chloride. Here you have two physical substances, chlorine and sodium, a gas and a metal, combined with each other. You will easily see that these two substances, as they are before they are captured by a formative entity and thereby crystallize into a chemical compound in cubes, each have completely different forms. Before they enter into this form principle, they have nothing in common; but they are bound together, taken up by this form principle, and this forms the physical body of table salt.
Thus, everything that appears as transformed nutrients in the human organism presupposes the lowest supersensible entity, the supersensible form. When new nutrients are to enter the human organism, which is already delimited from the outside by the action of the form principle, they must, under normal conditions, be taken up through the mouth into the digestive tract. In doing so, they undergo their very first transformation as soon as they leave the mouth. Further transformations are brought about by the digestive tract. These transformations of the most complex nature could not take place unless the human organism were integrated with a higher principle, which we have called the form principle, through whose activity the nutrients — which are initially neutral and indifferent to each other when they are taken in — are modified so that they become capable of forming living organs. Although it is a completely different process in humans because it takes place at a different level, we can imagine this transformation of nutrients in the human digestive tract in a similar way to how plants take up their nutrients from the mineral soil and transform them in such a way that they build up into the form of the plant in question. This is only possible because in plants the flow of nutrition is taken up by a life process or, as we say in occultism, by the etheric body as the first supersensible principle. In the same way, the nutrients entering the human organism are processed by the etheric body, that is, the etheric body ensures their transformation and their integration into the inner laws of the human organism. We must therefore regard this first supersensible member of the human being, the etheric body, as the initiator of the first transformation of nutrients. Once these nutrients have been transformed to such an extent that they are absorbed into the life process, they must be further processed and adapted to the human organism in the sense we have described in previous lectures. They must be processed in such a way that they can gradually serve those organs in the human organism that are an expression of the higher supersensible principles, the astral body and the I. In short, we must be clear that the higher principles, the astral body and the ego, must send down their peculiar kind of activity to the processes in the organs of the digestive system and that they must work down into the transformed nutrients.
The organs that we already know, which we have described as the seven organs of the inner world system, now oppose the flow of food. Let us once again sketch the inner world system of the human being in a very schematic way:
The nutrients are thus absorbed and initially processed in a variety of ways in the digestive tract, then they are counteracted by the liver, gallbladder, spleen, heart, lungs, kidneys, and so on. Now that we understand that these organs are designed by their corresponding force systems to further process the flow of nutrients, we can ask: What is the purpose of this further transformation? — If the food stream were only processed to the extent that it is in the digestive tract in order to serve the life form, then humans would only be able to lead an unconscious plant-like existence, because they would not have developed organs that can be tools for their higher abilities. However, the seven organs further transform the food stream, and we know that these processes are prevented from entering human consciousness by the sympathetic nervous system. Therefore, in the sympathetic nervous system, together with the seven organs, we have that which opposes the food stream.

This brings us to a high degree of penetration from the outside into the interior of the human organism. But what goes on inside, one might say as the mutual interaction of the seven organs, is something that could not happen anywhere else in our earthly world as it does there. It can only happen because this inner part is completely closed off from the outside world and the substances are prepared for this inner activity by the digestive tract. So we are now inside the human organism.
Now we have to note the peculiarity that, as we stand inside the organism, the organism must organize itself internally, differentiate itself internally. In order to meet all the demands placed upon it, the organism must develop a multitude of organs that work together. This multiplicity of organs is necessary for the manifold internal functions. We will see what must be achieved by this in the following. If we imagine that only the flow of food would be transformed by the seven organs of the inner world system, then human beings would never be able to reveal their essence to consciousness. He would not even be able to have the dullest form of consciousness, because everything that goes on there is veiled, kept away from consciousness by the sympathetic nervous system. A connection is therefore necessary between these internal organ systems, which are, so to speak, built up from the outside, and what lies further inside the human organism. This connection is established by the fact that, through everything that the nutritional process provides in its entirety, the entire form of the human organism is permeated by what we call tissue in the broadest sense. A certain type of tissue of the simplest organization permeates all the individual members of the human being, which is capable of transforming and developing itself in such a way that the most diverse organs can form. Certain types of tissue, for example, transform themselves by incorporating special cells to form muscles; others transform themselves by becoming solid and incorporating bone cells by appropriating the corresponding substances. Thus, in the individual organs of the human organism, we must always think of what underlies them, namely the tissue that pervades the body in all directions and from which the individual organs develop. However, even if this formative tissue were capable of growing and developing the most diverse organs, it would still be nothing more than something plant-like, for that is the essence of the plant world: that plant beings grow, that they produce organs from themselves, and so on. But as human beings rise above the plant realm, a completely new element must present itself to us, through which human beings are enabled to add to plant life that which lifts them above plant life. Human beings must add consciousness, initially in its simplest form, the dull consciousness that enables them to perceive their own inner life. As long as a being does not consciously experience its own inner life, as long as it is not yet able to reflect itself inwardly, as it were, in order to experience this own inner life, we cannot say that it has risen above plant life. It is only through this that a being rises above plant life, that it not only has life within itself, but consciously experiences this life, that it first reflects on these inner processes and experiences them.
How does experience come about in the first place? We have already formed a concept for this. In earlier lectures, we have already shown that experience comes about through processes of separation. Therefore, we must look for processes of separation as the basis of inner experience, of the dull experience of consciousness that pervades the inner life processes. We will have to assume that separation processes take place everywhere in the tissues; and indeed, these separation processes already meet us when we observe the human organism from the outside, when we see how substances are continuously absorbed from all parts of the tissue by what we call the lymphatic vessels, which run through the entire organism like a kind of other system alongside the blood system. The processes of secretion that convey the dull inner experience flow into the lymphatic system, so to speak, from all parts of the human organism. If we could imagine the entire blood system away in abstracto and if we could imagine the tissue as having nothing more of a blood-like character, we would have to imagine that higher processes take place in the blood system than in the processes of the lymphatic system. In these secretions, the human being feels, as it were, in a dull animal consciousness, his own physical body. It dimly reflects his organization. And just as, on the one hand, the sympathetic nervous system keeps everything that wants to rise up from the digestive and nutritional processes and the seven organs away from consciousness, so, on the other hand, a dull consciousness is formed, which is overshadowed by the bright consciousness of the I, like a faint light. a dull consciousness is formed, which is, however, overshadowed by the bright consciousness of the day in modern human beings. It is overshadowed by the bright consciousness of the ego, just as a weak light is overshadowed by a strong one. This dull consciousness is, as it were, the other side of that consciousness which uses the sympathetic nervous system as its instrument.
If human beings had developed their organism only to the point of forming the body tissues and organs necessary for internal digestion and for secretions into the lymphatic vessels, they would only be able to receive a dull awareness of their inner life. However, they would not be able to develop ego consciousness; they can only acquire this if they do not merely experience themselves internally, but also open themselves up to the outside world. Here we again see an opening up to the outside world. We have already discussed how breathing enables humans to connect directly with the outside world. Now we can go further and say: When we consider the inner human being, we can really only go as far as the digestive system, because we can say that insofar as the organs of the inner world system extend to the digestive tract, we can already see an opening up to the outside world in this contact between the inner world system and the digestive tract, because the human being is, as it were, ready to take in nutrients from the outside. By coming into close contact with nutrients taken from the environment, he is actually no longer only internal. We have learned about another opening up to the outside world in breathing, and it can be seen to an even greater extent in those organs that serve the soul functions.
Thus we see how the conscious life of the human being is based, on the one hand, on a dull inner life and, on the other hand, on the ability to open up to the outside world and to connect with it. Only through this can the human being be an I-being. Only by feeling not only the resistance within themselves in their processes of separation, but also the resistance that the external world opposes them, can human beings develop their ego-consciousness. Thus, the fact that human beings can open themselves up to the outside world again provides the basis for their physical ego-hood. But this also means that human beings must have the opportunity to develop the organ of this selfhood in the most diverse ways. And we have seen how the organ of selfhood, the blood, is integrated into the organism and how the blood circulation permeates all organs in order to be a tool for selfhood. Just as the ego spiritually and soulfully permeates and interweaves the entire human being, so the blood circulation physically permeates the entire human organism, turning, as it were, in two directions: toward the inner being of the human being with its seven organs, and so on, and then we have again an opening up toward the outside, an entering into connection with the outer world. We can therefore speak in the highest sense of the word of a cycle of forces that lie behind physical phenomena and find a point of connection through the ego.
Now we must examine the individual phases of this cycle in more detail. First of all, we must once again follow the process of nutrition, the absorption of nutrients, which, , by being grasped by the etheric body, or rather by the force of the etheric body, become a living stream in the human organism; then the inner world system, the seven organs, stands opposite them, because — as we have already seen — otherwise human beings would not be able to go beyond a plant-like existence. At a further, higher stage, it is necessary that the functions of these seven organs oppose the flow of nourishment. Thus, what comes from the actual astral nature of the human being opposes the animated flow of nourishment; the flow of nourishment comes from outside, and what is the inner human nature opposes it. First, the food stream, i.e., the absorbed external world, encounters the etheric body, which transforms the nutrients in the digestive system; then the astral body of the human being opposes it, further transforms the nutrients, and structures them in such a way that they become more and more adapted to the inner activity of the organism. In its further course, the stream of nourishment must also be grasped by the forces of the ego, of the blood itself. This means that the instrument of the ego must reach down with its activity to the point where the stream of nourishment is absorbed. Does the blood do this? Is what we must say from occult observation true?
Yes, the blood is driven down into the organs of nutrition just as into all other organs. It undergoes a process in the organs of nutrition through which it can become the complete instrument of the human ego in the physical world. We know that the blood, as the instrument of the human ego, must undergo a transition from so-called red blood to blue blood. The ego works with its instrument, the blood, down to the beginnings of the digestive and nutritional processes. Here we are again faced with resistance. How does this happen? It happens when the blood enters the liver through the portal vein system and there, from blood that has been transformed, so to speak, bile is produced, and the bile in turn directly opposes the flow of food. Here in the bile, we have a wonderful connection between the two ends of the inner human organization. On the one hand, the food stream absorbed by the digestive tract represents the most external material that enters our physical organism; on the other hand, there is the ego, the most precious thing that human beings can have within the earthly world, with its tool, the blood. The ego establishes a direct connection with the outermost material by preparing the bile at the end of the blood process via a detour through the liver, and in the bile, the ego—in the transformed, changed blood—opposes the flow of food.
Here we see the ego working down into the coarsest material and then highly organized substances such as bile emerging from it. And anyone who wants to understand these intimate processes between blood, bile, and the nutritional process can find something in these facts that makes many secrets of the human organism appear clearer to them; and if they follow these processes further, they can for example, abnormal processes such as those resulting from a backflow of bile, a return of bile into the blood in what is known as jaundice, more correctly and treat them. But it would go too far today to go into such things in detail.
So we see how the seven organs extend down into the activity of the etheric body and have absorbed the influences of the ego from above. So we have something in the bile that, under the influence of the ego, directly opposes the flow of food. If the bile wants to act on the flow of food, which has already become alive in the digestive process, it must also be able to oppose it as a living substance. This happens because it is formed from an organ that belongs to the seven members of the inner world system that animate the inner being of the human being, so that the bile, as inner life, encounters that which comes from outside.
Just as bile is connected to the liver, we find the liver in turn connected to the spleen. When we consider these organs—the liver, bile, and spleen—we must say that it is these organs that directly oppose the stream of nutrition and transform it so that it becomes capable of ascending to higher levels of human organization. However, they also have to supply those organs that open to the outside world, namely the heart, the lungs, the digestive tract itself, and above all the organs of the head, the sense organs.
We have already established that all inner experience is closely connected with processes of secretion. That is why we have examined these processes of secretion in particular. In terms of these processes in the overall organization, the liver, gallbladder, and spleen do not initially have anything to do with processes of secretion; they do secrete substances, but this has to do with nutrition. They convey the ascending life that turns from the lowest forms of life toward the organ of consciousness, toward consciousness itself. But when the heart joins these organs as a fourth organ and the heart also opens up to the outside world through the circulation of blood, the human being gains his ego-consciousness. However, he would not be able to experience this ego as something that stands opposite the external world if he did not relate this outward-looking ego to what he already possesses as a dull consciousness of his inner bodily life. They must add another process to the secretions of the inner organism, one that also gives them an experience of their inner life with the ego, which has its instrument in the blood.
At first, through the separation of the lymph, man experiences his inner life only in a dull consciousness. But then it must also be possible to separate from the blood, and in this separation man becomes aware that he stands face to face with the external world as an inner self. However, human beings would face the external world in their experience in such a way that they would lose themselves internally if they did not know that what breathes the air and takes in and processes nutrients from the outside is the same essence as what they experience internally. The fact that human beings do not lose themselves, that they face the external world with their own being, is made possible by the fact that they secrete carbon dioxide from the transformed blood through the lungs and secrete the transformed substances that come out of the blood through the kidneys.
This characterizes the function of both the organs that mediate an ascending process (liver, gallbladder, spleen) and those that mediate a descending process (lungs and kidneys). However, we must not schematize here — that is not possible at all in theosophical considerations — we must see that the lungs, by opening themselves to the outside, also mediate an ascending process. We thus see how these seven most important links in the inner human world system are connected with the inner experience of the human being and with the opening up to the outside world. On the one hand, these seven links transform the inherent activity of the nutrients into the inner activity of the organism and supply the human organism with these transformed substances. They make it possible for the human being to open up to the outside world again. But they also make it possible for what humans develop as excessive inner activity to be expelled to the outside world through the secretions of the lungs and kidneys. Through the work of the lungs and kidneys, we therefore have a regular regulation of the activity of the human organ systems. This entire relationship between the human organ systems is expressed in such a way that, in occultism, there is no better way to describe it than to say: The heart, as the sun, stands at the center and influences the three organs of the inner world system that are responsible for the ascending processes: the liver, the gallbladder, and the spleen. Just as in the macrocosm the sun stands in the planetary system in relation to the outer planets Jupiter, Mars, and Saturn, so in the microcosm, in the human organism, the inner sun, the heart, stands in relation to the liver-Jupiter, the gallbladder-Mars, and the spleen-Saturn. I would have to talk not for weeks, but for months, if I wanted to explain to you all the reasons why, based on precise and intimate occult observation, the relationship of the sun to the outer planets of our planetary system can truly be paralleled to the relationship that the heart has in the human organism to the inner world system, to the liver, gallbladder, and spleen. The external relationship is in fact so perfectly reflected in the interaction of these organs that what happens in the great world of the macrocosm, in our solar system, is mirrored there. And it is equally justified to say that the processes taking place between the sun and the inner planets down to our earth are reflected in the relationship of the heart to the lungs and kidneys. Thus, in this inner world system of the human being, we have something that reflects the outer world system.
In the course of these lectures, we have already indicated how, when we dive down clairvoyantly into our own inner being, we cease to perceive our inner organs only as they appear to the outer eye. We must go beyond the fantasy image that the external anatomy makes of our organs by rising to contemplate the real form that these organs have when we take into account that these organs are actually systems of forces. The external anatomy cannot possibly reveal the real nature of these organs, for it sees in them only the transformed food substances that have been stuffed into them. And precisely because external science will accept only this view, it cannot recognize the inner force systems that underlie the organs. But those who are able to see through clairvoyant observation what underlies these organs as power systems see how justified it is to name the organs after the planets, because they recognize how the relationship between the planets of our outer world system is repeated in our inner organ system.
Yesterday we said that the organs can develop too much inner activity. Each individual organ can develop too much activity, and this irregularity can manifest itself in such a way that it affects the entire organism. Yesterday I already pointed out that when such excessive inner activity causes something like a stubborn life of its own to arise in the inner organs, it is necessary to counteract this with something that dampens these inner activities. This means that if the internal organs convert the external activities of the nutrients too strongly, if they produce too strong an internal transformation product, then we must counteract them with something from outside that restrains them, that dampens the excessive internal activity.
How can this be done? If we want to target an organ of the internal system that is developing excessive internal activity, we must look for something in the external world that has the opposite activity and introduce it into the organism in order to combat the excessive activity of the organ. This means that we must try to find external activities that correspond to the activities of the individual organs. In the Middle Ages, people still knew a great deal about how substances in the environment, i.e., external substances, can counteract excessive activity of the organs. To modern people, who often encounter such things only in distorted writings from the Middle Ages, in which they can see nothing but colorful superstition, this sounds very strange. But occult science has carefully, deeply, and thoroughly investigated the correspondence between the organs of the inner world system and certain external substances for thousands of years, and countless observations made with clairvoyant eyes have proven that, for example, the excessive activity of the inner Jupiter, the liver, can be curbed by the metal substance of tin. We combat the excessive inner activity of the bile with that which is expressed in the metallic substance of iron. This is not surprising, because iron is the only metal that we must have in our blood as an essential component for the tool of the ego, and we have seen that the gall is precisely the organ that mediates the connection between the ego and the densest material stored in the human being, the flow of nourishment. Similarly, we can say that the spleen has its external counterpart in the metal lead. The heart—the sun—corresponds to gold. The lungs—Mercury—as the name itself says, correspond to mercury, and the kidneys to the metal copper, that is, Venus. (This is written on the board:)
Saturn Spleen Lead
Jupiter Liver Tin
Mars Gallbladder Iron
Sun Heart Gold
Mercury Lungs Mercury
Venus Kidneys Copper
Now, if we want to combat the excessive activity of the inner organism with the activity found in these metals, we must be clear that that everything in the organism is more or less interconnected and that the individual organ systems are formed in parallel with each other, so that humans did not first arise as headless beings; rather, the organs that are connected to the upper blood circulation, the brain-spinal cord system, form naturally at the same time as the organs of the inner world system.
Just as we have seen that there is an upward and a downward blood circulation, so too do we have an upward movement of the lymphatic process, which we have recognized as a dull consciousness, toward the upper parts of the human organism. And it is now a fact that what is incorporated into the upper bloodstream corresponds in a certain way to what is incorporated into the lower bloodstream, and we can see that the metals mentioned above also have a relationship to the upper organ system of the human being. You know that the lungs open outward to the larynx, which is an organ of the upper human organism. Just as we see a connection between the gall in the lower organ system and iron, we can connect iron in the upper organ system with the larynx. These things are difficult, of course, but I would like to hint at some of them. Just as we have noted a connection between bile and the larynx in relation to iron, there is also a certain correspondence in relation to tin — Jupiter — between the upper part of our head with everything that belongs to the forehead and brain formation, and the liver; and in relation to lead — Saturn — a correspondence between the back of the head and the spleen.
In this way, we have been able to extend our considerations to everything that is integrated into the human blood circulation in the seven members of the inner world system, and to how it is connected with the outer world. We can consider these correspondences for both normal and abnormal life. These correspondences between metals and internal organs present us with a highly interesting fact. And if the information contained in our therapeutic books were to be examined and compiled systematically rather than chaotically, these correspondences would prove themselves quite naturally from external facts. And if such explanations are still regarded as figments of the imagination today, the occultist can remain quite calm, for he knows that the time must come when external facts will confirm his assertions.
Now we must not think that, for example, in the case of kidney disease, we should simply administer ordinary copper; that would of course be a mistake. If we want to introduce metallic substances into the organism, we must heat them so that they turn into a kind of metallic vapor. This produces something like vaporous particles, and in this form the metallic properties can act on the internal organs. If we now take the blood system, metals would be of no help in cases of disease. We have already pointed out that a kind of salt deposit occurs in the blood system. And just as the metallic substance acts on the internal organs, so the salt-like substance acts on the blood system. If we want to influence the blood system by external means, we must supply it with salt-like substances. This can be done by inhaling salty air, by salt baths, or the like. However, we can also add salts or salt-forming substances from the other side, through the digestive process, so that we are able to induce the process of salt formation and salt deposition from two sides.
If you remember what I said yesterday about the physical effects of the inner mental and spiritual processes, you will easily understand that everything that is contrary to the processes acting in metals is the physical effect of the emotional processes, for these emotional processes are closely connected with the swelling processes in the blood, which can be stopped by the introduction of external metallic substances that exhibit the opposite activity. If, for example, digestive activity becomes excessive and develops its own activity where the flow of nutrition is taken up by the etheric body, we can counteract this by supplying suitable salts; for if the etheric body exaggerates this process of taking up the flow of nutrition, this means that too much salt is being absorbed. It must be dampened by the supply of external activity from a salt.
Then we have processes that take place externally as combustion or oxidation processes; these are processes in which something combines with the oxygen in the air. All substances that combine easily with the oxygen in the air radiate their activity most widely through the organism when they are absorbed into it. While salts, when we introduce them into the organism, only affect the organism to a moderate degree, the metallic nature can affect the inner world system. And in the air, that is, in the substances that easily combine with the oxygen in the air, we have something that, when absorbed into the body, radiates through the entire organism into the blood system. We can thus understand that through such processes, which create excessive inner activity in the development of heat, which is, after all, the external expression of the impulses of the will, we feel ourselves being influenced throughout our entire organism. This is not the case with the organic repercussions of thought; when we focus our attention on these, we feel that these effects only take place in certain organs. You can see from this how extraordinarily complicated the entire apparatus of the human organism is and how complicated its relationship to the outside world is.
We have now shown how the human organism with its own inner activity can be opposed by the external, inorganic, inanimate nature, and how salts and vaporized metals can influence the organism. But we also have the possibility of influencing humans from other areas of nature. We can counteract the human organism with the active forces found in the plant world. If we simply consume a plant remedy as food, we would not achieve much because, as we have seen, the internal organs ensure that the substances we ingest are stripped of their own activity. If the plant is to be absorbed into the human organism in such a way that it continues to work in its capacity as a plant, this cannot happen if we consume it as food. This plant substance cannot influence the ego, because the plant has only an etheric body as its highest member. The plant substance is therefore simply absorbed where the food stream is captured by the etheric body, so that the plant substance cannot yet be considered as a remedy in the digestive tract, but only in those organs in which, in addition to the etheric body, the astral body of the human being is already active. For this reason, the plant begins to work only on the inner world system and on the sympathetic nervous system and the lymphatic system. The effect of the plant no longer extends to where the human being opens up again to the external world through the blood. The plant is assigned to the middle part of the human organism, so that everything that can be sought in the plant in terms of activity can only act on everything that belongs to the inner world system and on the corresponding organs of the head and the upper part of the organism. When the activities and functions of these organs are disturbed, when they function abnormally, then the influence of the plant world comes into play to combat this.
We have thus discussed the effects of metals, salts, and plants. It is not appropriate at this point to discuss further ways of combating irregularities or disturbances in the human organism, not so much because time is too short, but mainly because theosophists are best advised to stay away from all areas that are currently the subject of partisan disputes. What has been listed so far does not belong to the disputes between parties; one can simply accept it, and then one will see its correctness; or else people will consider it pure nonsense, fantasy. That does not matter. For as a theosophist, one would have to remain silent if one did not want to say all the things that people consider nonsense. But if we wanted to investigate the effects of animal substances on humans, we would get into the dispute between the parties, and one might then think that Theosophy wanted to interfere in this dispute between the advocates and opponents of healing methods in the animal realm. And it can never be the task of theosophists to get involved in such fanatical disputes, for then we would run the risk of abandoning the objective, universal human standpoint.
But we have seen, even if only in outline, that this human organism is a complex system of individual organs that are at different stages of development and are connected in the most diverse ways with each other and with the organism as a whole. What is visible as the physical organism of the human being, what we can see with our eyes and touch with our hands, is only a part of the human organization; but the supersensible, which works into it, we do not perceive in this way with the senses; it is revealed only to the spiritual eye of the seer. We cannot therefore say that all organs have developed equally, but it has been shown that we must view the human organism in such a way that we can recognize older and younger elements within it. We have already emphasized, for example, that we must regard the brain as an older, more highly developed organ than the spinal cord, and that the brain was formerly, in a sense, at the stage of the spinal cord. In the same way, we can look at the digestive and blood systems in relation to the lymphatic system. Here we have to place the lymphatic system comparatively at the level of the spinal cord; it is therefore the younger system, while the complex digestive and blood systems have already undergone many transformations and are older than the lymphatic system, which does not open to the outside and secretes its substances only inwardly into the tissues. This is a very important point of view. We must therefore regard our present lymphatic system as something which, if it were not incorporated into the other systems, would develop into a digestive and blood system.
We have a simpler system for transmitting consciousness in the lymphatic system; the more complicated one is found in the digestive and blood systems. We must therefore look for organs in the human organism that have emerged from organ systems that previously had other tasks. The statements made here could also be clearly proven to external science if one were to familiarize oneself with them. Everything that has been said about the transformation of organs can be proven by embryological investigations. In every living being, that which appears later in the course of development is already preformed in the germ. If we go back from the developed human organism to the fertilized germ, we could find, using suitable methods, the complicated organ systems already hinted at in their very first stages, and in such a way that even in their very first stages they already show how they actually relate to each other.
If you look at what we have before us as the outer covering, as the boundary of the human being in his skin, and then at what leads to the sensory organs embedded in it, you will be able to say that everything that is present in this outermost boundary of the human being must already have been transformed from something else. For it is already a very complicated system, to which the brain also belongs; and it is impossible to conceive of a brain without lengthy preparation. We must therefore think of the outer covering of the human being as a product of transformation, just as we have described the brain as a transformed spinal cord and the digestive and blood systems as products of the transformation of the lymphatic system. While the spinal cord and the lymphatic system showed an ascending tendency in earlier stages, we must say that the present spinal cord and lymphatic system are in a state of descending development. It could also be shown that blood in its present configuration is a double product of transformation. By opening up to the outside, the digestive and blood systems become a transformed lymphatic system. If the digestive system with its movements had developed only inwardly, it would be completely closed off from the outside, and we would have in it an activity similar to that of the present lymphatic activity. In the latter, only what is supplied through the tissues is absorbed.

Thus, on the one hand, in the outer boundary of the human being, in the skin system, we see a transformation from another system, the blood system, which I will draw here, and in the digestive system we also see the transformation from another system, which is now in a descending stage of development. We must now try to determine whether we can already find indications of this ascending and descending nature of organ systems in the germ layer. And indeed, we find that the entire organism is indicated in the germ layer — I will draw it schematically — in the four germ layers lying one above the other, which are called: the outer germ layer — ectoderm — the inner germ layer — endoderm — and the mesoderm — the outer and inner middle germ layer.

In accordance with our view of development, we must regard the outer germ layer, the ectoderm, which in modern anatomy is also called the skin sensory layer, as a product of transformation that shows its first signs in the outer middle layer, the outer mesoderm. In this, we have before us as a germ layer what appears at a higher stage in the skin sensory layer. And in the inner middle layer, the inner mesoderm, we have before us the younger formation of what later appears in the endoderm, in the intestinal gland layer.
When we look at the human germ in its development, we have indicated the first germ of the human being in the two middle germ layers, the mesoderms; the other two germ layers, the ectoderm and endoderm, have already been transformed. The two middle layers are therefore those that represent the original state, while the ectoderm and endoderm show the higher development.
Now we know that the germ potential of the human being flows together from two sources, the female and the male germ potential, and that a new development can only arise through the living interaction of these two sources. The two germ sources must therefore contain separately all the processes that together form the germ potential for the human organism.
What does occultism tell us about the conditions prevailing here? It shows us that under today's physical conditions, the female germ [endoderm] is only capable of producing a human body that, if it were to develop on its own, would not be able to develop what we call the form principle, which ultimately leads to the formation of the skeletal system that gives humans their solidity; nor would the main sensory system be provided by the female germ. The female germ is so constituted that one could almost say that what arises from it would be too good for the world as it exists today, for not all the processes necessary for such an organism are present in the external physical world. This female human organism could not, so to speak, progress to that “earthing” expressed in the stored bone system, and it would not have the possibility of being connected to the outside world through the senses. It would have to find support in the external conditions to balance its softer inner material, which it would have instead of the solid skeleton; it would not be able to open up to the outside, but would remain closed in its inner life. This is the female contribution to the germ cell; it would go beyond what is possible in our earthly existence today, simply because the physical conditions on Earth today do not provide the conditions necessary for such a refined organism, which is so ill-suited to earthiness and opening up to the outside world. Under present-day earthly conditions, such an organism would be doomed to death from the outset. Thus, precisely because of the tendency for human beings to go too far in their development, the human germ is already imprinted with the cause of human mortality.
The other part of the germ, the male [ectoderm], is in exactly the opposite position. If the male germ cell developed on its own, this would lead to a powerful unfolding of what manifests itself in the opening up to the outside world in the skin sense system, and of what leads to solidification in the bone system, thus overshooting the mark on the other side. Such one-sidedness would be just as incapable of producing a viable germ as the female germ alone, because the organism that the male germ would develop would unfold such powerful forces that it would have to destroy itself and perish under the conditions that exist on Earth today, that is, it would not be able to exist as an organism under these conditions on Earth today. The male germ can therefore only come to a viable expression when it interacts with the female germ. Only through the balancing of the two germ elements, through the balancing of that which is destined to die in the female germ element with that of the male germ element through the process of fertilization, is a living whole human organism possible. The forces that are compressed in the male germ would, if they were to grow out on their own, lead infinitely downward into the earthly realm; they would lead to a much greater hardening of the skeletal system, to a far greater opening up and merging with the outer world. These two organic germs must come together for further development right from their very first emergence, because individually each of them is doomed to death. Only the living interaction of what prevents one from gaining the upper hand over the other on both sides results in the germ potential that is possible for human existence on earth.
Thus we see, even if only in a sketchy way, that we can trace spiritual facts back to the point where human beings produce their own kind. We could, of course, describe this in much greater detail, but it is impossible to say everything in a short cycle. If we were to look even deeper, we would see how even the most minute details can be traced back to spiritual facts, right down to what has been said here about the supersensible force systems that find their outer expression in the organ systems that human beings develop so that their species can live on Earth.
We have seen that the earth, as the result of the densest “process of earthification,” has produced in us the skeletal system, and as the least condensed, the most active, the blood system. And it should only be added briefly that everything that takes place in the earthly-physical human organism penetrates up to the processes that take place in the blood; these are the warming processes. In these warming processes of the blood, we see the direct expression of the I and thus the highest level, and below it the other processes of the human organism. The warming process is therefore the highest; it is here that our I-soul activity intervenes directly. That is why we also feel something like a transformation of our ego-soul activity into an inner warming, which can go as far as physical warming in the blood process. We see, then, how the spiritual-soul activity, proceeding from above downward, intervenes in the organic, the physiological, through the warming process, and we could show by many other facts how the spiritual-soul activity comes into contact with the organic in warming processes. We also have warming processes through the activities of the organs of nutrition. Through the activity of the complex apparatus of the digestive system, the most diverse transformations take place, through which heating processes occur in the physical organism. These extend from below to above. In the heating process, the physical organism of the human being thus extends up to the spiritual-soul realm. Do the transformations stop there? Or do they continue? What follows can only be hinted at; it must first be left to further reflection and, in particular, to the intuition of each listener. If we can view these transformations with a sense of genuine awe for the human organism, we learn to understand that physiology need not be a dry science, but can be a source of the highest human knowledge.
What the organism produces in terms of internal heat in our blood, in terms of the heat it transmits to us through all its internal processes, shows that we can see something in the heating processes like a blossoming of all other processes in the organism. The internal heat of the organism penetrates up into the spiritual-soul realm and can transform itself into the spiritual-soul realm. This is the highest, the most beautiful thing that can be transformed from the physical into the spiritual-soul realm through the power of the human body. When everything that is inherent in the human earthly organism has been transformed into warmth and this warmth is transformed by the human being in the right way, then compassion and interest in other beings arise from the inner warmth. When we ascend through all the processes of the human organism to the highest level, the warming processes, we pass, as it were, through the gate of the human organism, which is formed by the warmth processes, up to the point where the warmth of the blood is utilized by what the soul makes of it. Through a living interest in all beings, through compassion for everything around us, we expand our spiritual-soul life over the entire earthly existence as our physical life leads us up to warmth, and we become one with the entire existence. It is a wonderful fact that the world being has taken the detour through our physical organism in order to ultimately give us the inner warmth that we humans are called upon to transform through our ego into living compassion for all beings.
Heat is transformed into compassion in the earthly mission!
We use the activity of the human organism, so to speak, as heating energy for the spirit. This is the meaning of the earthly mission, that the human being as a physical organism is embedded in the earthly organism in such a way that all physical processes ultimately find their completion, their crown, in the warmth of the blood, and that the human being as a microcosm, in fulfillment of his destiny, transforms this inner warmth in turn, in order to radiate it as living compassion and love for everything that surrounds us. Through everything we take into our soul out of living interest, our soul life is expanded. And when we have then passed through many incarnations in which we have utilized all the warmth that has been given to us, then the earth will have achieved its goal, which was to be fulfilled within the earth mission, then it will sink down as an earthly corpse and be consigned to decay. And the totality of all those human souls who have transformed physical warmth into warmth of heart will ascend. Just as the individual soul ascends to a spiritual world after passing through the gate of death, once the physical body has been surrendered to the forces of the earth, so too will the earth's corpse one day be surrendered to the forces of the worlds, and the individual human souls will progress to new stages of existence. Nothing in the world is lost. What human souls have achieved as fruits on earth will be carried over by human souls into eternity.
Thus, spiritual science allows us to connect the physiological processes in the human organism to our eternal destiny. If spiritual science (theosophy) is not mere theory, not merely abstract knowledge, but if we regard it as showing us that we as human beings do not stand alone on the earth, but belong to the entire world system — and if we learn to think about the destiny of human beings in such a way that they take the forces from the earth in order to work into eternity, then through spiritual science (theosophy) we take up what must be achieved through it. And when people who sense or recognize this high ideal come together in brotherhood and agree in their striving, that is, when we recognize that within ourselves we have the seeds for further development that can bear fruit for the further development of the earth and humanity, then we can feel with all modesty that as theosophists (anthroposophists) we can contribute to the fulfillment of the Earth's mission through the development of our own powers.
We have gathered here and will now go out again to live our lives, perhaps taking with us some of what has been presented here only in outline as inspiration, and continuing to develop it further. But even though we are scattered throughout the world, we want to work together harmoniously in living thoughts and feelings and with all our will. In this spirit we want to part from one another, and in this spirit we want to find each other again when the opportunity arises.
