Deepak Chopra, founding president of Maharishi Ayur-Veda Products International, Inc (MAPI), the American Association of Ayurvedic Medicine and former medical director of the Maharishi Ayurveda Health Center for Stress Management and Behavioral Medicine, says, according to Stephen Barrett in an article in the journal "Alternative Medicine and Ethics", that "If you have happy thoughts, then you make happy molecules. On the other hand, if you have sad thoughts, and angry thoughts, and hostile thoughts, then you make those molecules which may depress the immune system and make you more susceptible to disease." Barrett goes on to say that, while the TM technique and other relaxation techniques may temporarily relieve stress, claims made by Chopra that happy or sad thought may affect the molecular levels of the body and the immune system have no scientific basis.
