I. Soul and Spirit in the Human Physical Constitution

This is even more emphatically the case when we come to consider the airy organism which is permeated by the forces of the astral body. The air within us at a certain moment was outside us a moment before, and it will soon be outside again. We are drawing in and giving out the airy element all the time. We can really think of the air which surrounds our earth, and say: it penetrates into our organism and withdraws again; but by penetrating into our organism it becomes an integral part of it. In our airy organism we actually have something that constantly builds itself up out of the whole atmosphere and then withdraws again into the atmosphere. Whenever we breathe in, something is built up within us, or, at the very least, each indrawn breath causes a change, a modification, in an upbuilding process within us. Similarly, a destructive, partially destructive, process takes place whenever we breathe out. Our airy organism undergoes a certain change with every indrawn breath; it is not exactly newly born, but it undergoes a change, both when we breathe in and when we breathe out. When we breathe out, the airy organism does not, of course, die; it merely undergoes a change; but there is constant interaction between the airy organism within us and the air outside. The usual trivial conceptions of the human organism can only be due to the failure to realize that there is but a slight degree of difference between the airy organism and the solid organism.
