Lecture VI
In a drawing it would look like this. Suppose this is the mass of the brain (green). Once the human being has been born his spirit and soul element stops short before it (red). The brain is so constituted that the human being's inner spirit and soul element cannot pass through the brain. In his brain the human being is not filled with his spirit and soul element. Instead, external perceptions can enter and make themselves felt in the brain through the senses—let me draw an eye here. Put another way, the constitution of the brain is such today that the eternal aspect of the human being cannot rise up into it. Instead, external impressions can enter. By being given the draught of forgetfulness the pupil gained the possibility of receiving into his brain what was his spiritual and soul element before conception or before birth (red). That is the one side.
