The word Yoga means union. It means union of mind with body. Yoga is way of life for human beings since thousands of years, seemingly beginning with the people of the Indus valley region. Sages of India were deeply committed to yogic practices (self-study). As there was increasing influence of Buddhism and interaction with neighbouring cultures, such as the Chinese and Tibetans. Aspects of spiritual practice, philosophical belief and medicinal understanding were being shared and Yoga was one of the aspects, which invariably led to cultures influencing one another. Yoga had origin in India and is considered to be one of the key branches of Ayurvedic medicine.
