In the present time, yoga has attracted all kinds of professionals and got its alliance in almost all subjects. Study of yoga has been prominent in the curricula of Sanskrit studies, from which it evolved traditionally, but it has of late found relevance in other disciplines like Philosophy, Psycho-logy, Sociology, Music, Physical Education and Sports, Physiology, Medical Science, Bio-chemistry, Life Sciences, and Language and Literature. There are exclusive departments of yoga in various universities. The present book helps to address the yoga needs of people from all walks of life and presents the Yogic view from its origin and development to the needs of a modern, technocratic society. With the observance of Yogic practices, the Indian spiritual gurus kept their body healthy and tuned, and elevated their mind to higher realms, which were essential requirements for their spiritual growth, for happiness and harmony in life. This ancient science found easy acceptance in foreign countries too. With the UNESCO coming into picture, yoga shot into limelight around the world. Apart from spirituality, other reasons for the revival of yoga as a lifestyle were its simple, light exercises which rejuvenate the mind and body, its no-harmful effects, and its power to inculcate superior values in life. Yoga has an edge over other health exercises like aerobics and weight lifting. Fitness of body and mind, work performance, psycho-physical balance and the overall well-being are easily attainable through the regular practice of yoga. The present book will be useful to a common reader and a seeker of yoga alike in knowing about its philosophy and will help them practise it in a simple, lucid way.
