Brian L. Weiss is a prominent American psychiatrist and author, renowned for his work in past-life regression therapy. He earned his medical degree from Yale University and completed his residency in psychiatry at the Yale University School of Medicine. Initially focused on traditional psychiatry, Weiss’s career took a pivotal turn when he encountered a patient, Catherine, who, during therapy, began recalling past lives. This unexpected experience led him to delve deeper into the concepts of reincarnation and the spiritual aspects of human consciousness.

His groundbreaking book Many Lives, Many Masters recounts Catherine’s journey and how past-life regression therapy alleviated her anxiety. Weiss’s work challenged conventional psychiatric practices, merging spiritual beliefs with therapeutic techniques. He has since become a pioneer in the field of past-life regression and frequently conducts workshops and lectures on spiritual healing and regression therapy. His books, including Only Love is Real and Messages from the Masters, have influenced countless individuals seeking deeper understanding of their lives and spiritual connections.
