Abstract
There is a worldwide interest in yoga for wellness, mind-body medicine, research in consciousness, prevention/management of life-style disorders and spiritual quest for self-realization. An important question is "Is yoga a therapy or a lifestyle?" However, the universe of yoga has many sets and subsets, evolved over millennia, by great yogis and acharyas. The proliferation of the names of yoga, by several teachers and schools, is often guided by the motive of creating a brand rather than a revival, renewal or renaissance in yoga. The latter demands a panoramic overview of tireless endeavor of great masters, beyond any commercial interests, in exploration of "The Science of Yoga." Sincere and meticulous enquiry into the physiological and psychological effects of yoga began, a century ago, in a quiet hamlet in Amalner, Maharashtra.
