I think death is the end of all that exists. No soul, no afterlife to toil with and certainly no "churasee lakh jooni".
From a atheistic/scientific/logical explanation death brings about the end of all neurological activity. We literally cease to exist (like becoming a stone). Thoughts and notions/perceptions of oneself cease to exist and we are suspended into a world of chaos (of which noone knows anything about).
When we take heavy doses of any tranquilizer our neurological activity is significantly supressed, we go to sleep, our neurological activity is supressed more! Im guessing that death would most likely be similiar to this deep sleep chaotic state in which we have no perception of the self. death is like deep sleep except theres no waking up.
Most people are afraid of this reply and completely avoid this as a possibility. But being the pathetic creatures that we are we will do anything to prevent our utter destruction and annhilation from this universe thus we have Relgion give us the notion of eternal life. Sure helps calm us down and releive us from the stress of dying.
but then again what do i know?
