In the beginning was the yoga of Purusha and Prakriti

Rudolf Steiner:  "... the origin of the world resides in that cosmic being who is beyond all concepts, not to be reached by any of the means that are applied nowadays to explaining the world. In the primal Divine Father — says the Gnosis — lies the ground of the world, and only in what proceeds from Him do we find something to which the soul can struggle through if it turns away from all material conceptions and searches a little for its own innermost depth. And this is Silence: the eternal Silence in which there is neither space nor time, but silence only. It was to this duality of the primal Father and the Silence preceding time and space that the Gnostic looked up; and then, from the union of the primal Father with the Silence, as it were, he conceived other existences proceeding: one can equally well call them Worlds or Beings. And from them others, and again others, and again others — and so on through thirty stages. And only at the thirtieth stage did the Gnostic posit a condition prior to our present mentality — a condition so delightfully explained by Darwinism in terms of that mentality. Or, strictly speaking, at the thirty-first stage — for thirty of these existences, which can be called Worlds or Beings, precede our world. “Aeon” is the name generally given to these thirty Beings or Worlds that precede our own."
