"Initial incarnations are not reincarnations; they are just the first time an individual tries to run a body."

so...how many 'individuals' are there? If one individual has run more than one body, where were they all when the world population was, say....1 billion instead of 6 billion? Who--or what 'chooses' whether to come back or not? Is overpopulation the result of 'individuals' not having the good sense to give others a turn? *grin*

My...all sorts of metaphysical conundrums once you take that first step.
