Yoga: A way of life that involves physical exercise, ethical precepts, and dietary prescriptions. Yoga 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.

During the past 80 years, health professionals in India and the West have begun to investigate the therapeutic potential of yoga. To date, detailed research studies have shown that with the practice of yogic meditation, a person can indeed learn to control such physiological parameters as heart rate, blood pressure, respiratory function, metabolic rate, brain waves, skin resistance, body temperature, and other bodily functions.
