Then we find, tracing it onward, that this great age passes, and the world begins to rise out of the waters. How then shall types be brought forth in order that evolution may go on? The next great type is to be fitted either for land or for water; for the next stage of the earth shows the waters draining gradually away, and the land appearing, and the creatures that are the marked characteristic of the age must exist partially on land and partially in water. Here again there must be manifestation of the type of life, this time of what we call the reptile type; the tortoise is chosen as the typical creature, and while the tortoise typifies the type to be evolved, reptiles, amphibious creatures of every description, swarm over the earth, becoming more and more land-like in their character as the proportion of land to water increases. There is meanwhile going on, in the "imperishable sacred land," a preparation for further evolution. There is one part of the globe that changes not, that from the beginning has been, and will last while the globe is lasting; it is called the "imperishable land." And there the great Ṛishis gather, and thence they ever come forth for the helping of man; that is the imperishable sacred land, sometimes called the "sacred pole of the earth." Pole itself exists not on the physical plane but on the higher, and its reflection coming downward makes, as it were, one spot which never changes, but is ever guarded from the tread of ordinary men. There took place a most instructive phenomenon. The type of the evolution then preceding, the Tortoise, the Logos in that form, makes Himself the base of the revolving axis of evolution. That is typified by Mandâra, the mountain which, placed on the tortoise, is made to revolve by the hosts of Suras and Asuras, one pulling at the head of the serpent, and the other at the tail--the positive and negative forces that I spoke of yesterday. So the churning begins in matter, evolving types of life. The type is ever evolved before the lower manifestation, the type appears before the copies of it are born in the lower world. And how often have the students of the great Teachers themselves seen the very thing occur; the churning of the waters of matter giving forth all the types of the many sorts and species that are generated in the lower world; these are the archetypes, as we call them, of classes and creatures, always produced in preparation for the forward stretch of evolution. There came forth one by one the archetypes, the elephant, the horse, the woman, and so on, one after another, showing the track along which evolution was to go. And first of all, Amṛita, nectar of immortality, comes forth, symbol of the one life which passes through every form--and that life appears above the waters the taking of which is necessary in order that every form may live.
