why not ask shirley macLaine instead?
the laws of karma and reincarnation are man made and wretched. if you travel to places in the world where people truly believe, you will find the true nature of it and how it holds people in its grip. thanks to lack of education and with the help of men like deepak chopra, westerners have a very watered down idea of it.
see there are many problems with the salvation-by works doctrine of reincarnation. first, there are many practical problems. for example:
1. why does one get punished for something he or she cannot remember having done in a previous life?
2. if the purpose of karma is to rid humanity of its selfish desires, then why hasn't there been a noticeable improvement in human nature after all the millennia of reincarnations?
3. if reincarnation and the law of karma are so beneficial on a practical level, then how do advocates of this doctrine explain the immense and ever worsening social and economic problems, including widespread poverty, starvation, disease, and horrible suffering in india, where reincarnation has been systematically taught through out its history?
the way i see it..It's just a matter of "faith" that is unprovable, kind of like proving "Jesus' existence" or "resurrection", "santa", "the cookie monster" or "the tooth faerie". so as there's no scientific evidence, except anecdotal, for reincarnation of the "soul" there is little reason to believe in it. and i don't. however the biogeochemical cycle is scientifically true. when i die i'll become part of the sulfur cycle. that's the meaning of "to be made flesh again" that i go by. personally.
