IV. Rhythm in the Bodies of Man

We must look at the human being in a way that makes it possible to understand this fact and many others besides. You know from the innumerable times we have referred to it that man can only be understood when we know that he has a fourfold structure of physical body, etheric body, astral body and ego. These four members of man's being are connected with and dependent on one another in the most manifold ways. Each member influences the other, and therefore they are in constant connection one with another. But this cooperation is very complicated. It takes a very long time for man to get to know these connections as well as the relationship of these members to certain forces, processes and beings in the cosmos as a whole. For man has a connection with the cosmos through each of his members; a connection which is continuous—and this again is very important—but which is also variable. What we know as the physical body, etheric body and so on are connected with one another but also with the cosmos, the whole world about us. For what we have within us is also to a certain extent outside us, and so we could say that we can best get to know these inner and outer connections if we observe man both in a waking and sleeping state.
