Letters of Sri Aurobindo
8. Rebirth
Fragment ID: 683
The soul after it leaves the body travels through several states or planes until the psychic being has shed its temporary sheaths, then it reaches the psychic world where it rests in a kind of sleep till it is ready for reincarnation. What it keeps with it of the human experience in the end is only the essence of all that it has gone through, what it can use for its development. This is the general rule, but it does not apply to exceptional cases or to very developed beings who have achieved a greater consciousness than the ordinary human level.
It is not the soul (the psychic being) that takes a lesser form, it is some part of the manifested being, usually some part of the vital that does it, owing to some desire, affinity, need of particular experience. This happens fairly often to the ordinary man.
