Many Lives, Many Masters: The True Story of a Prominent Psychiatrist by Brian L. Weiss

Psychiatrist Brian L. Weiss describes his experience with a patient whose recollections under past-life therapy seemed connected to her recurring nightmares and anxiety. Weiss, trained as a traditional psychotherapist, presents his initial skepticism and how his outlook changed.

He also recounts messages he attributes to the patient channeling from the “space between lives.” This is the author’s personal account and interpretation, not established clinical evidence for reincarnation or past-life therapy, and it is no substitute for professional mental-health care.
