Kriya Yoga is a very specific system of Yoga that was revived in modern times by Lahiri Mahasaya, c 1861. Paramahansa Yogananda brought it into widespread public awareness through his book Autobiography of a Yogi. The system consists of a number of yogic techniques that are believed to hasten the practitioner's spiritual development and to help to bring about a profound state of tranquility and God-communion.
