Man is spiritual being -- a soul, in other words -- and that this soul takes on different bodies from life to life on earth to order at last to arrive at such perfect knowledge, through repeated experience, as to enable one to assume a body fit to be the dwelling-place of a Mahatma or perfected soul. Then, they say, that particular soul becomes a spiritual helper to mankind.
