Here's my submitted response to the question: Do you believe in rebirth?
1) No and yes. As Carl G. Jung said to the question "Do you believe in God?", I say, "I don't believe; I know."
2) Also, cross-culturally, Jung said that all cultures have some variation of rebirth/reincarnation incorporated in their worldviews.
3) This life is the proof of life after death. There is no logical basis to say this is the "first life" or refute this is a "rebirthed life."
4) I've experience past life memories that are equal to any early childhood memory.
5) The logic that no physical energy is lost, but only changes form, applies equally to the mind energy of empty-suchness and its change of form from one life to another.
6) No individual ego-self or 'soul' is reborn, but the wave formation patterns of karma are perceived as "transmigrated" from the perspective of our constructed time-space continuum. A single life is like a single peak of a wave in an ocean that not move horizontally; it moves vertically up and down. The karma wave is what moves horizontally, so the Lankavatara Sutra says it is the ocean that is reborn in each peak, not the person of the previous peak.
