It all depends on each person's faiths and beliefs... But in all faith,s there is a concept of life after life...

Death is nothing but the beginning of life.

What we do now, in our present life, is nothing but sowing seeds for our entry in the new life. Some call it Karma.

I highly recommend you read the book "Life after Life" by Raymond Moody. Its a good book which has discussed this in good detail.
