Self-Realization Fellowship (SRF) is a worldwide religious organization founded in 1920 by Paramahansa Yogananda, the Indian guru who authored Autobiography of a Yogi. 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 came to the West in 1920 and in 1925 established SRF's headquarters at Mount Washington, Los Angeles, California. Before his return visit to India in 1935, he legally incorporated SRF in the United States, designating it as the only organization to carry on his work – to care for and disseminate his teachings.

Paramahansa Yogananda was an Indian-American Hindu monk, yogi and guru who introduced millions to meditation and Kriya Yoga through his organization, Self-Realization Fellowship (SRF) / Yogoda Satsanga Society (YSS) of India – the only one he created to disseminate his teachings. A chief disciple of the yoga guru Swami Sri Yukteswar Giri, he was sent by his lineage to spread the teachings of yoga to the West. He immigrated to the US at the age of 27 to prove the unity between Eastern and Western religions and to preach a balance between Western material growth and Indian spirituality. His long-standing influence in the American yoga movement, and especially the yoga culture of Los Angeles, led him to be considered by yoga experts as the "Father of Yoga in the West". He lived his last 32 years in the US.
