3. The Metamorphoses of the Earth

Now, what is the significance of this division that took place in our earth's predecessor during the evolution of the old Moon? It lies in the fact that along with the sun the higher beings and the finer substances withdrew from the whole stellar mass as sun, while the coarser substances and the lower beings remained with the Moon. So during the evolution of the old Moon we have two heavenly bodies instead of one: a sun body, harboring the higher beings, and a Moon body, the dwelling place of the lower beings. Had the whole remained united, with no separation occurring, certain beings who developed on the sundered Moon could not have kept pace with the sun beings: they were not sufficiently mature, and therefore had to segregate, cast out, the coarser substances and build for themselves a sphere of action apart. Nor could the higher beings have remained united with these coarser substances, for it would have obstructed their more rapid progress. They, too, required a special field for their development, and that was the Sun.
