Yoga: A way of life that includes ethical precepts, dietary prescriptions, and physical exercise. Its practitioners believe that their discipline has the capacity to alter mental and bodily responses normally thought to be far beyond a person's ability to modulate them.

To date, thousands of research studies have been undertaken and have shown that with the practice of yogic meditation a person can, indeed, learn to control such physiologic parameters as blood pressure, heart rate, respiratory function, metabolic rate, skin resistance, brain waves, body temperature, and many other bodily functions.
