Lecture II

When does the third dimension show itself in a distinct, conscious way? Actually, it only appears to our consciousness in the act of walking. When we move from one place to another, then the line which is this third, vertical dimension changes continually, and although our consciousness of this third dimension while we walk is almost imperceptible, we must not overlook it. In fact, the half-conscious intellectual awareness we can experience is related to this height dimension.  Figure 3 Certainly in our casual outer consciousness we don't take into account the changes in position of this line representing the height dimension. But in general when we walk and exercise this walking as an act of will, we continually reestablish the line. We have to say: The delicate consciousness of what is happening in the third dimension when we walk is similar in kind to the delicate consciousness of depth in our act of seeing. If I want now to draw the dimensional aspect of what happens in the activity of the body through the legs and feet, we can say: In the act of walking we can experience an intellectual awareness of activity going on in all three dimensions. So I have to draw the act of walking with three full lines.
