Self-Realization Fellowship (SRF) is a worldwide, spiritual organization founded by Paramahansa Yogananda in 1920 and legally incorporated in the United States as a non-profit religious organization in 1935. Before coming to the United States, Yogananda began his spiritual work in India in 1917 and named it Yogoda Satsanga Society of India (YSS). He then founded SRF in 1920 which became the international headquarters for the SRF and YSS, located on Mount Washington in Los Angeles, California.

Yogananda's teachings include yoga techniques and a form of meditation that promotes awareness of one's soul and expands one's consciousness. Self-Realization Fellowship disseminates and publishes his teachings, which are guided by his Aims and Ideals. SRF 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.
