Rebirth is an affirmation that must be counted among the primordial affirmations of mankind. The concept of rebirth necessarily implies the continuity of personality. Here the human personality is regarded as continuous and accessible to memory, so that, when one is incarnated or born, one is able, potentially, to remember that one has lived through previous existences, and that these existences were one's own, ie, they had the same ego form as the present life. As a rule, reincarnation means rebirth in a human body.
Carl Jung
