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.
I have been asked many times, Why do you laugh so much and make so many jokes? I become serious sometimes--when I have a stomachache! The Lord is all blissfulness. He is the reality behind all that exists. He is the goodness, the truth in everything. You are His incarnations. That is what is glorious. The nearer you are to Him, the less you will have occasions to cry or weep. The further we are from Him, the more will long faces come. The more we know of Him, the more misery vanishes.
-Swami Vivekananda
