According to Osho, at death the soul leaves the body and becomes unembodied—merging with the whole, beyond time and space. Most people re-enter a suitable womb within seconds; highly evolved or deeply depraved beings must wait until matching parents appear, experiencing bliss or torment meanwhile. These in-between states gave rise to symbolic ‘heaven’ and ‘hell’; real evolution resumes only in a new body.
When you die, you drop the body and rest in a timeless space until the right parents are found; if you were very good you feel bliss, if very cruel you feel your own pain, and then you’re born again.
