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.
Let us make our hearts as big as an ocean, to go beyond all the trifles of the world and see it only as a picture. We can then enjoy the world without being in any way affected by it.
-Swami Vivekananda
