Lecture XXVI
Now the Arupa-Sphere densified; everything emerged as thought-forms. The whole Earth was filled with these; it was as though one were looking into a great model filled [with] small crystals. Present within it as models were all the forms of human beings, animals and plants. Spiritual beings worked on these as a master builder works on his models. They were put together from outside. The whole then passes over into astral substance. The astral Earth-Globe came into being. In between there were short Pralayas. Now again we have to do with the outwardly-working divine powers who poured forth the astral substance, filling the forms with light and colour. Here are to be found all the astral forms of human beings and animals, as well as the whole plant kingdom, in a great astral sea. This then densified ever more and more and the physical Earth arose as the Fourth Globe.
