Lecture I

On the outside, it expresses itself only through the fact that we can call ourselves completely grown up inwardly and outwardly in the late twenties. Everything that comes from the head completes itself really only at this time. The head is in reality only seven years old at 28. So, this is something, which one has therefore in the entire being of man. As one has on one side respiration and blood circulation—how blood circulation is in relation to respiration—the same way in life, in the whole becoming of life, the processes of the head are in relation to the processes, which proceed from the digestive system, altogether form the metabolic limb system. That also has one to the other the beat, of one to four. This is of great importance for life. It means, for example, that everything we bring to a child in education or instruction between the seventh and 14th years lives only in the head very slowly and has come to an end there, so that it is caught up in the head up to the 35th year; only up to the 35th year of life its vibrations in the head have completely come to an end. Four times seven years come into consideration. (The four times seven year periods are repeated from the seventh year on) Then at 35 only, the head has really caught up.
