The first Buddhists regarded life (jiva) as a process of consciousness moving through a succession of bodies, death being only a momentary event to this process. This phenomenon is sometimes called ‘moving from womb to womb’ (Sn.278) or more precisely, rebirth (punabbhava, D.II,15). Later Buddhist thinkers explained rebirth in complex and minute detail – death-proximate kamma (marana samma kamma), last though moment (cuti citta), relinking (patisandhi), the underlying stream of existence (bhavanga sota), etc. Interestingly, none of this was mentioned by the Buddha, much of it is not even to be found in the Abhidhamma Pitaka. It is the product of speculation dating from the early centuries CE onward. This is not to say that such concepts are valueless, but it is important to distinguish between early, late and very late Dhamma concepts.
