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 JungThe great decisions of human life have as a rule far more to do with the instincts and other mysterious unconscious factors than with conscious will and well-meaning reasonableness. The shoe that fits one person pinches another; there is no recipe for living that suits all cases. Each of us carries his own life-form- an indeterminable form which cannot be superseded by any other.
Carl Jung
