Self-Realization Fellowship (SRF) is a worldwide spiritual organization founded by Paramahansa Yogananda in 1920 and legally incorporated as a non-profit religious organization in 1935, to serve as Yogananda's instrument for the preservation and worldwide dissemination of his writings and teachings, including Kriya Yoga. Yogananda wrote in God Talks With Arjuna: The Bhagavad Gita that the science of Kriya Yoga was given to Manu, the original Adam, and through him to Janaka and other royal sages.
Self-Realization Fellowship continues to disseminate Paramahansa Yogananda's teachings following his stated Aims and Ideals. SRF publishes Yogananda teachings of home-study lessons, writings including Autobiography of a Yogi, lectures, and recorded talks; oversees temples, retreats, meditation centers, and monastic communities bearing the name Self-Realization Order. It also coordinates the Worldwide Prayer Circle, which it describes as a network of groups and individuals who pray for those in need of physical, mental, or spiritual aid, and who also pray for world peace and harmony.
