Origin of the Soul and the Purpose of Reincarnation serves as a complement to prior books on reincarnation written by Dr. Semkiw, such as Born Again and Return of the Revolutionaries, which focus on cases that demonstrate objective evidence of reincarnation. Dr. Semkiw draws upon independent research to better understand the nature of the soul and how reincarnation works. He also utilizes information gathered through Kevin Ryerson, a trance medium who has been featured in Shirley MacLaine's books. Topics covered include when and how souls were created, how personality is determined, and the nature of time and space. Split incarnation, where one soul inhabits more than one body at a time, as well as ghosts, astrology, the Kabbalah and Enneagram are also addressed. Stages of initiation, identified in the life of Jesus, are reviewed, and child prodigies are explained through reincarnation. Respected clairvoyants have contributed to this book including Echo Bodine, Judy Goodman, Wayne Peterson, and Michael Tamura.
