In due time the point of greatest density, the nadir of materiality, is reached. From that point the life begins to ascend into higher Worlds, as evolution proceeds. That leaves the denser Worlds depopulated, one by one. When the purpose has been served for which a particular World was created, God ends its existence, which has become superfluous, by ceasing within Himself the particular activity which brought into being and sustained that World. Worlds are the first created and the last eliminated, while the three densest Worlds, in which our present phase of evolution is carried on, are but comparatively evanescent phenomena incident to the spirit's dip into matter.
Evolution is the fanning process which is to accomplish that end.
In the virgin spirits are enfolded all the possibilities of their Divine Father, including the germ of independent Will, which makes them capable of originating new phases, not latent in them. Prior to the beginning of the pilgrimage through matter the virgin spirit is in the World of Virgin Spirits, the next to the highest of the seven Worlds. It has Divine Consciousness, but not Self - consciousness. That, Soul-power, and the Creative Mind, are faculties or powers attained to by evolution. When the virgin spirit is immersed in the World of Divine Spirit, it is blinded and rendered utterly unconscious by that matter.
