Persinger performed similar research in Toronto and Ottawa. Contents TM and Cult Mania takes a look at the assertions made by the Transcendental Meditation movement and analyzes them from a scientific perspective. The book acknowledges that those who practice the Transcendental Meditation technique feel relaxed and experience an increase in creativity. According to the book, the physiological effects reported by the scientific studies on Transcendental Meditation are relatively small from a scientific perspective and "no more effective than many other meditation techniques". Transcendental Meditation is seen as most noteworthy due to its ability to manipulate stress and expectancy. "Transcendental Meditation has achieved international recognition through commercial exploitation" and "poor scientific procedures", write the authors. The book notes, "Frankly, the reported effects of TM upon human behavior are trivial. Considering the alleged potency of the TM procedure, the changes in physiological and behavioral measures are conspicuously minute." TM and Cult Mania comes to the conclusion that, "science has been used as a sham for propaganda by the TM movement." Reception A capsule review of the book for the Los Angeles Times, Phil Freshman commented, "Using hard logic and crackling humor, a trio of Canadian laboratory researchers cogently deflates Transcendental Meditation; they spotlight transparencies in its claims and warn of its latent hazards to those in wobbly mental health." In his book Rational Mysticism, author John Horgan comments that although Persinger says he's neutral toward religious belief, he's more biased than other neurotheologians and that his two books "cast religious belief and spiritual practices in a psychopathological light".
