Is it possible to predict the far distant future? It is indeed possible, because all that has finally to become physical in the future, already exists in germ, in archetypal form. The plan of evolution is contained in archetypal thought. Nothing comes into being in the physical world which in its broad lines has not been foreseen and prefigured in the devachanic world.
