Yoga philosophy is one of the six systems of Hindu philosophy, which exist in India since ages. Unlike many other established philosophies across the world, it is only philosophy which has its practical base too. Yoga is an exact science based on certain immutable laws of nature. It is well known to people of all countries of the world interested in the study of eastern civilization and culture, and is held in awe and reverence as it contains in it the master-key to unlock the realms of Peace, Bliss, Mystery and Miracle. Even the philosophers of the West found solace and peace in this divine science.
