Many Lives, Many Masters is the true story of a prominent psychiatrist, his young patient, and the past-life therapy that changed both their lives. He held steadfastly to conservatism in his profession, distrusting anything that could not be proved by traditional scientific method. But when he met his 27-year old patient, Catherine, in 1980, who came to his office seeking help for her anxiety, panic attacks, and phobias, he was taken aback at what unfolded in the therapy sessions that followed, which jolted him out of his conventional ways of thought and psychiatry.
