Wondering about life after death............

Hi arun, Hinduism believes in this concept of rebirth and reincarnation.It starts with Vishnu having dashavatara which is the base of Hinduism. There are many stories connected with rebirth and some of them have baffled many scientists and other learned people.However there is hardly any way of knowing it because it is difficult to conclude unless you experience it, and even if that is the case. it may be difficult to convince other people...We will forever be questioning such claims...

No one knows. I havn't heard anyone who can remenber his/her preexistence, also nobody come back from heaven, hell or such places. So it's none of our business. just as we needn't to pay any attention to what happened before the big bang.
