Lecture II
Here lies a boundary in front of man. His being, what he himself is, is here represented in the aura by what I nave made run from bright green into blue violet (see diagram 2). But by passing over into blue-violet it leaves off being man and becomes the encircling cosmos. There with his being, which is the inner force of his world outlook, man comes to a boundary; there in a sense he reaches nothingness and he has to hold fast to concepts having no content—concepts such as matter, atom, substance, force. This lies in the human organization, it lies in man's connection with the whole cosmos. Man's connection with the whole cosmos actually stands out in front of him. If we describe this boundary in accordance with the ideas of spiritual science, we can do so by saying (diagram 3): this boundary allows man with his soul to come into contact with the universe. If we indicate the direction of the universe in one loop of a lemniscate we can with the other loop show what belongs to man, only what proceeds from man goes out into the universe, into the infinite.
