He had a career to protect, a reputation built on decades of rigorous psychiatric training. And then a patient began speaking — under hypnosis, in an ancient voice — about his dead son. About things she could not have known. He had a choice: protect the career, or follow the truth. He chose the truth. What he found changed the lives of millions of people who needed someone with his credentials to say: this is real.
Who Is Brian Weiss?
Brian L. Weiss, M.D. (born November 6, 1944) is a Yale-trained American psychiatrist and former head of the Psychiatry Department at Mount Sinai Medical Center in Miami. He is best known for his landmark 1988 book Many Lives, Many Masters, which documented his experience with a patient — pseudonymously called Catherine — who recalled 86 past lives under hypnosis.
The Catherine Case
Catherine came to Weiss for anxiety and phobias. During hypnosis, she began describing past lives in vivid detail. What convinced the skeptical Weiss was not the past-life memories themselves but the “Masters” — discarnate beings who communicated through Catherine with information about Weiss’s deceased father and infant son that Catherine had no normal means of knowing.

- Trained over 5,000 therapists in past-life regression techniques
- Published 11 books, translated into 30+ languages
- Brought past-life therapy into mainstream psychiatric discourse

Critical Perspectives
Cryptomnesia hypothesis: Critics suggest that apparent past-life memories may be forgotten experiences from this life resurfacing in distorted form. Counter-evidence: Stevenson's verified cases were documented before investigation, ruling out post-hoc confabulation in the strongest cases.
Suggestion under hypnosis: Hypnotic subjects are susceptible to suggestion from therapists. Counter-evidence: Newton used open-ended, non-leading questions; subjects from different countries and belief systems described the same architecture independently.
Neurological explanation: The experiences may reflect complex brain states rather than actual non-physical reality. Counter-evidence: Van Lommel's 2001 Lancet study documented verified NDE perceptions during confirmed cardiac arrest with flat EEG.
Develop Your Reincarnation Intelligence (RQ)
The Weiss test: He risked his professional career to follow a truth he could not ignore. What truth in your own life are you currently managing around — acknowledging enough to not deny it, but not enough to act on it? That gap is the next frontier of your RQ.
For skeptics in your life: Weiss is your most accessible entry point for conversations with scientifically-minded people who dismiss reincarnation research. A Yale-trained psychiatrist who changed his framework based on evidence is harder to dismiss than a spiritual teacher who "always believed."
- Practice: Many Lives, Many Masters is short. Read it in one sitting if you can. The Weiss effect — what happens to a rigorously trained skeptic when confronted with evidence he can't explain — is itself instructive.
