Five different forms of rebirth are defined and described.
Metempsychosis, or transmigration of souls, is described as life extended in time by passing through different bodily existences, an eternal life interrupted by different reincarnations.
This concept does not require a continuity of personality, even in Buddhism where it is of particular importance, but only continuity of karma.
In reincarnation, human personality is regarded as continuous; previous existences are at least potentially available to awareness, since the same ego is presumed to exist throughout the various lives.
These lives are generally thought to be exclusively human.
The third form of rebirth, resurrection, is defined as a reestablishment of human existence after death, with the implication of some change or transformation of the being.
A different place or body may be involved in transformation; the change of body can be either in the carnal or the nonmaterial sense.
Rebirth in its fourth form (renovatio) is described as rebirth within the span of individual life; this rebirth may either consist of some healing or strengthening of a part of the physical or psychological being without essential change of the whole, or of a profound basic change in the essential nature of the individual, called transmutation.
Examples are offered such as the assumption of the body of the Mother of God into heaven after her death.
The fifth form of rebirth is seen as an indirect one in which the individual witnesses or takes part in some rite of transformation and thereby shares a divine grace.
It is exemplified by the witnessing of transubstantiation in the Mass, or the confession of the initiate in the Eleusinian mysteries. ~Carl Jung, Vol. 9, Part 1; Pages. 113-115).
