Religion and Reincarnation

Recently there was much discussion on a book called "Born Again" by Walter Semkiw . In it the author claimed that he knew all about the past lives of certain famous people like Shah Rukh Khan , Amitabh Bacchan , Jawaharlal Nehru etc .

In Hindu religion , in practically every religion in the world , reincarnation is mentioned , if not treated as an established fact .

Now what do we mean by reincarnation?

In Bhagvad Gita Lord Krishna says that the human body is transient , that the only thing that remains constant is the aatma or the soul ,which "cannot be burned by fire , soaked with water , in short , cannot be destroyed or killed ". The soul can take different forms and these are called reincarnations of that soul . Just as a person changes new clothes for old , so too the aatma changes one body for another .

In Buddhism and Sikhism ,too, being offshoots of Hinduism , the concept of reincarnation is very much an accepted fact .

In all these religions reincarnation revolves around karma , i.e , the simple concept of action and reaction . In simple words , good deeds beget good times and bad deeds beget misfortunes .

In Christianity , too , the concept of reincarnation exists . Christ himself was resurrected after his physical body "died" on the cross .

This particular book was different (at least to me it was ) in that , it said that it was possible for one soul to take on multiple bodies at the same time .
I found this a novel concept and thought about it for quite some time afterwards . In Hindu religion one soul taking on one body is accepted , but not this concept of one soul and multiple bodies . The reason I pondered over this matter for so long , however , was that I kept remembering a few dialogs from the Ramayana which run as follows :

Lakshmana(on spotting the golden deer ):Brother , I do not trust this phenomenon . It is against Nature . There cannot be a Golden Deer . It is a trick , for never has such a creature been heard of or seen or even imagined .

Rama : Brother , just because one hasn't heard or seen or imagined a particular phenomenon does not mean that it is impossible . For , there are many things of which humans are not aware but which do exist nonetheless . Nothing is ever against Nature . For , the Almighty has thought of all things even before they were imagined by humans .

If the Lord has already thought of all things even before they are imagined by humans , then why is this concept of multiple reincarnations at the same time unacceptable ?? For it to have occurred to Walter Semkiw ( the author of this book ) , it should have occurred to God first isn't it ??

I am still no nearer to finding the answer to this question than I was before . Hence this blog .

I hope someone out there will know the answer !!
