There is really no magic.

The concept of a soul that exists apart from the body has been accepted by almost all religions and near death experiences seem to indicate that spirit and body are separate. The existence of reincarnation is disputed by Christianity and Islam. Most people do not remember a previous life and it is not possible to find conclusive scientific proof for the existence of reincarnation. Dr. Ian Stevenson did extensive scientific research into the subject, and his studies indicate the existence of reincarnation.

After reincarnating most people begin afresh as a blank page. Someone who is Jewish now may have been an SS officer in a concentration camp before. A black man who is blaming the whites for his situation, may once have been a white slave trader. A Klux Klux Clan member hating blacks may have been black before. A young Palestinian may have been a Jewish settler previously. There is no evidence of spiritual growth after reincarnation. Reincarnation is not more than recycling a process thread in a virtual reality. Past memories can even be made available by The Programme to arbitrary persons, making it seem reincarnation.
