No death, no birth.

Since there is no real death, there is no real birth. There is only a change of energy. What you perceive as past lives is merely another form of what is. God is not punitive, and therefore you can never accept your current life as a punishment or a making good for what was never accomplished previously. You evolve, you grow, and all that you experience is a part of that evolution, but you do not make up for what was lost, for nothing is lost. You merely evolve. You merely convert your energy from one form to another. Human life is a part of that continuity of conversion.
