Lecture I
Indeed, as soon as we pass the threshold of the spiritual world, with our whole being we feel that we are entering into three worlds—actually three worlds. We must never lose sight of the fact that once the threshold of the spiritual world is crossed we have the distinct experience of three worlds. We actually belong to these three worlds in the very construction of our whole physical body. I might say that the working together of three worlds, comparatively independent of one another, is a necessary factor in the wonderful structure of man as he confronts us in the physical world. When we consider the formation of our head, the formation of all that belongs to our head, we must be clear, even when only speaking of the head, that the formative forces of our head and the beings who are working and creating in these formative forces, belong to an entirely different world from, for example, the formative force of our breast, the formative force of all that has to do with our heart, including our arms and hands. To a certain extent it is as if the formative force of these material parts of man were to belong to a quite different world from the formative forces of our head. The lower organs of the body to gather with the legs, in their turn, belong to an entirely different world from the other members referred to.
