The following is a summary of Râja-Yoga freely translated from the Kurma-Purâna. The fire of Yoga burns the cage of sin that is around a man. Knowledge becomes purified and Nirvâna is directly obtained. From Yoga comes knowledge; knowledge again helps the Yogi. He who combines in himself both Yoga and knowledge, with him the Lord is pleased. Those that practice Mahâyoga, either once a day, or twice a day, or thrice, or always, know them to be gods. Yoga is divided into two parts. One is called Abhâva, and the other, Mahayoga. Where one's self is meditated upon as zero, and bereft of quality, that is called Abhava. That in which one sees the self as full of bliss and bereft of all impurities, and one with God, is called Mahayoga. The Yogi, by each one, realises his Self. The other Yogas that we read and hear of, do not deserve to be ranked with the excellent Mahayoga in which the Yogi finds himself and the whole universe as God. This is the highest of all Yogas.
