Brian Weiss

Brian Weiss (1944–present) is an American psychiatrist (Yale-trained, former chair of psychiatry at Mount Sinai Medical Center in Miami) who became one of the most popular proponents of past-life regression therapy.

In his bestseller Many Lives, Many Masters (1988), he recounted treating a patient (“Catherine”) who, under hypnosis, spontaneously recalled apparent past lives and relayed messages from “the Masters” between lifetimes — after which her phobias and anxieties resolved.

Weiss concluded that traumatic memories from previous incarnations can drive present-day symptoms and that recalling and releasing them under hypnosis can heal. He has since built a large practice, training program, and series of popular books around the technique.

Weiss is a major node in the survival strand and in popular mind-body-spirit healing, asserting that consciousness persists across lifetimes and that working with past-life material has therapeutic power.

FLAG: these claims are strongly contested. Hypnosis is well documented to produce confident but confabulated, suggestion-shaped “memories” (the false-memory and “fantasy-prone” literature), so “recovered past lives” are widely regarded by clinicians as therapist-cued narratives rather than evidence of reincarnation.

The therapeutic benefit some patients report may stem from suggestion, catharsis, and the therapeutic relationship rather than literal past lives. Weiss represents the popular, clinically-credentialed but scientifically-disputed end of survival work — distinct from Stevenson’s cautious field research.
