One of the best books I have read that brings all the major religions - both ancient and modern - under the one umbrella of Truth as it pertains to Reincarnation and Karma. If you are still having trouble understanding these two concepts, you won't after you read this book. Very satisfying!
Written close to a century ago, this is still a relevant and timeless text. Atkinson does a great job in developing, in a logical order the societal history and application of Reincarnation and the Law Of Karma. He traces the concept of Transmigration of souls through Egyptian, Chaldean, Druid, Roman, Greek, Jewish, Essene, Early Christian, Hindu societies. He then explores current modern applications (remember he is a contemporary of Madame Blavatsky) and the explores issue sof what happens between Incarnations, issues of Justice and Incarnation, and then presents a an argument for and against Reincarnation. Finally he reviews the Law of Karma. I think that this book, in tandem with "The Kybalion" will evoke the reader to explore Blavatsky's "Secret Doctrine" and other related Theosophical works. I would rate this a "must have" for any serious spiritual library.
