Paramahansa Yogananda (1893-1952) was the first Hindu teacher of yoga to settle in the United States for an extended period, some 30 years. Soon after he came to the United States in 1920, he began teaching yoga to Americans. He launched th. Self-Realization Fellowship (SRF) in 1925. Yogananda saw yoga as uniting science and religion through realization of the unity of their underlying principles; he was among the first to emphasize the “mind-body” relation, especially for health and healing. The popularity of the movement and of Yogananda was enhanced with the publication of his book, The Autobiography of a Yogi (l946).
