This is the authoritative text book of Yoga, one of the six systems of Indian philosophy. Sanskrit Text and translation with commentary which provides a full picture of what Yoga is, what its aims are, how it can be practised, and what liberation of the soul means.
If a person who lives in God becomes miserable, what is the use of living in God? What is the use of such a God? Throw such a God overboard into the Pacific Ocean. We do not want such a God!
-Swami Vivekananda
