Siehe: Letters on Yoga, Vol. I, The Purpose of Avatarhood, S. 402 The Hindu procession of the ten Avatars is itself, as it were, a parable of evolution. (Memento vom 13. März 2007 im Internet Archive): The involution is of the Divine in the Inconscience and it is done by the interposition of intermediate planes (overmind etc., mind, vital – then the plunge into the Inconscient which is the origin of matter). But all that is not a process answering to the evolution in the inverse sense – for there is no need for that, but a gradation of consciousness which is intended to make the evolution upwards possible.
