Seventh Lecture
We know that the earth was a water-earth, and the formation in the water attained an ever lower stage during the time preceding the departure of the moon. When the moon withdrew, man's lower nature was at about the stage of a great amphibian. This is what the Bible calls the serpent, and what is elsewhere called the lindworm or dragon. During the time when the moon was withdrawing, more and more of the animal kingdom had worked itself into the lower human form. When the moon finally left, man had a hideous animal-like form in his lower parts, although above he still had the last remnants of a light-form into which the forces of the sun flowed from without. It was still possible for the light-beings to work into man. He moved about in the primal ocean, floating and swimming, with this remarkable light-form protruding out of the water-earth. What was this light-form? In the course of time it had transformed itself into a powerful and comprehensive sense-organ. When the moon withdrew, this transformation was complete. When man swam in the primal ocean, if some dangerous being approached him, he could perceive it with this organ. Especially could warmth and cold be perceived with it. This organ later shriveled up, so that today it is the so-called pineal gland. At that time man moved within the earth-mass, floating and swimming, using this organ as a sort of lantern. In very young children we still find a soft place in the head, and it was from there that this organ protruded into cosmic space.
