Lecture III
Let us recall what is described in Occult Science—how from the Lemurian Age onwards souls gradually came down from the other planets (with the exception of one principal human pair who had stayed on earth) and were incarnated in human bodies throughout Atlantean times. We must accordingly think of Earth-evolution as being such that the souls withdrew from the Earth's cosmic surroundings and at various points of time took up again their evolution on Earth. We know that before the Lemurian Age they had gone away to other planets. But we know also that the evolution of the Earth had been exposed to the attacks of Lucifer, and later to those of Ahriman. Thus the souls of men had to enter into bodies wherein they were exposed in the course of human evolution to the attacks of both these spiritual Beings. If nothing further had come about—if, that is, the human souls had come down from planetary existence into evolution on Earth, there to encounter the Luciferic and Ahrimanic influences—then something else would have happened to them as they went through subsequent incarnations; something I did not intimate in Occult Science, for at the present day one cannot say everything in public.
