Many Eastern relegions believe in life after death ( reincrnation).
There is a verty nice book by a spiritual master from Inida on the subject titled “Life beyond Phyiscal death” which can be downloaded from:

This book is good in very good in concept.
Recently , there are a lot of reseacher taking interest in the subject after a reputed US doctor Dr. Brain Weiss ( www.brainweiss.com)
wrote some best sellers ( many lifes many masters and a few more).
Most western relegions do not believe in Reincarnation.
I would be intersted in more references on the subject.
