Query: Greatest Book Ever Written on Out of Body Travel

What a great book. I could not put it down. I stayed up all night reading it, it moved me that much. It's well written and he describes in detail his travels with his 15th Century Tibetan Spiritual Mentor Rebazar Tarzs. He's either got the greatest imagination ever or as I truely believe it's an accurate account. If you read it with an open mind it will rock you from long held beliefs about life in the worlds beyond the physical. It's fascinating, enthralling and in the class of the best spiritual books ever written. It's right there with Gibran's works, Yogananda's, the Dali Lama, etc. Best read of 2003 for me. It will not disappoint any reader with an open heart. Highly recommeded, a can't put it down read!
