Fifth Lecture

This inner activity of thinking gives the first real insight into what is supersensible in man, the first stage. I would like to say: if one approaches man from the outside – and one can chart the whole blood dynamics – then in the blood dynamics one has, so to speak, a picture of man, of a part of man, seen from the outside. But by proceeding as I have indicated with regard to thinking, one comes to experience oneself inwardly filled with a second human being, with the human being who is independent of the physical organism.
