Yoga is one of the six longest surviving classic systems of Hindu philosophy in the world, which originated from ancient India some 5000 years ago. The term yoga comes from the sanskrit word “yuga”, which means union. Yoga masters (yogis) believed that the union of all aspects of an individual: body, mind and soul and the reunion of all opposites: mind and body, stillness and movement, masculine and feminine, sun and moon would lead to an inner illumination, the ecstasy of the true knowledge of reality.
