Lecture III
Still further behind there is what is called soul-light (yellow in diagram 8). To a certain extent attached to this soul-light, pressing itself through, there would be what is taken from the region of liking and disliking which I should have to give to the green area. Wishes, we should ascribe to the sphere of what is approximately blue. And now pushing up here, the real blue, that is approaching blue red, this would be the region of mobile susceptibility. These are auric currents that I here call burning desire, mobile susceptibility, and wishes. As you know, these auric currents, these auric streams, constitute the world of soul, they also constitute the man of soul and spirit who may be said to be built out of the ingredients of this soul world.
