While the book is very useful in some respects, I can't help but feel this guy is a scheister (sp). It's not that I don't believe a physicist can be multi-talented; it's that I question his background and his ability to preach the way he does. I think his exposition on karma is good, but the rest of it is based on...what?I also don't know if I believe in reincarnation, being a practicing Christian. Ofcourse, we all live on after death, but do we really return, life after life? How does this man know? I'm just a little skeptical about some of his presumptions. Does he have a doctorate in psychology?
