Brian Weiss writes popular spirituality and self-help books centred on past-life regression, reincarnation and hypnosis. Many Lives, Many Masters recounts his treatment of a patient he calls Catherine, whose hypnotic sessions led him to interpret reported memories as experiences from previous lives. Through Time into Healing and Only Love Is Real extend similar ideas into therapeutic and relationship contexts, presenting regression as a route to understanding fears, grief and recurring emotional patterns. Weiss's prose is accessible, anecdotal and written for general readers rather than as a technical psychiatry text. His work fits New Age spirituality, reincarnation and alternative self-help. The central claims about past lives are not established by mainstream scientific evidence, so readers looking for clinical guidance should distinguish these spiritual interpretations from evidence-based psychotherapy.
