Sixth Lecture

I already indicated yesterday that through the inner training of the soul, one can actually come to distinguish in the human being the actual physical body, then what I called yesterday – as I said, one must have terminology, and one does not need to bother about it — what I called yesterday the etheric body, which is the first supersensible link in human nature; that one then has to distinguish the astral body, which I also discussed yesterday in terms of its effect on kidney function, and finally the ego organization in the human being. When we speak of a person in a healthy or diseased state, it is always necessary to bear in mind that these four aspects of the human being have distinctly different functions that interact and exert mutual effects on one another in both healthy and diseased states. And only when one is able to visualize the unity of the human being from this confluence of four, I might say separate, levels of function, is one also able to gain a true conception of the healthy or the sick human being. I already mentioned yesterday: disease processes are, after all, natural processes. And with unbiased observation, one cannot really find a boundary between the so-called normal, healthy processes of the human organism and the diseased processes if one does not know this structure of human nature and thus knows: if any of these members interferes with the entire human unit more than it should interfere, then this is precisely how the abnormal, diseased functioning of the human being arises.
