I think scourge may be right, those concepts may be pointing to the same thing.
Now reincarnation is something I'll never know: Deep inside I think it's untrue, but there are evidences. I plan to buy I book when I arrange some money, Reincarnation Biology or something, two volumes with detailed studies including photographs of scars supposedly of the deceased person that manifested on the living reincarnation.
What I do believe is that a lot who claim to see past lives really did, and believed that. My conclusion is, that's a consequence of a kind of spiritual enlightment, and it may be true or not that it comes from reincarnation, but the feeling certainly is real (many think it can be just the conscience of the continuation of life and knowing that you came from a long line of ancestors). Another book I plan to read is the autobiography of an yogi. Those mystics, I believe they reached enlightment, and many of them claim past lives and believe in reincarnation.
