TM and Cult Mania is a non-fiction book that examines assertions made by the Transcendental Meditation movement (TM). The book is authored by Michael Persinger, Normand Carrey and Lynn Suess and published in 1980 by Christopher Publishing House. Persinger is a neurophysiologist and has worked out of Laurentian University. He trained as a psychologist and focused on the impacts of religious experience. Carrey is a medical doctor who specialized in psychiatry. He focused his studies into child psychiatry with research at Dalhousie University, and has taught physicians in a psychiatry residency program in the field of family therapy. Suess assisted Persinger in researching effects of geological phenomena on unidentified flying object sightings in Washington; the two conducted similar research in Toronto and Ottawa. TM and Cult Mania analyzes the efficacy or lack thereof of the TM meditation process, concluding that it is, "no more effective than many other meditation techniques". The authors write that, "Transcendental Meditation has achieved international recognition through commercial exploitation" and "poor scientific procedures". The book notes that physiological changes observed due to partaking in TM methodology are very small. Persinger, Carrey, and Suess conclude in TM and Cult Mania, "science has been used as a sham for propaganda by the TM movement." A positive capsule review in the Los Angeles Times noted that the authors use logic to point out transparencies in the assertions of Transcendental Meditation. John Horgan, in his book Rational Mysticism, questions Persinger's neutrality and says that in his book he treats religious beliefs and spiritual practices as mental illness.
