Swami Satyananda was born in Almora (Uttaranchal) in 1923. Drawn to spiritual life from an early age, he left home at the age of eighteen, and in 1943 surrendered himself to Swami Sivananda in Rishikesh who initiated him into Dashnami sannyasa in 1947. He served his guru for twelve years, perfecting every aspect of spiritual life. Thereafter, he travelled through- out the Indian subcontinent as a wandering ascetic.Realizing the need of the times as scientific rendition of the ancient system of yoga, he founded the International Yoga Fellowship in 1956 and the Bihar School of Yoga in 1963. During the next twenty years, Swami Satyananda hoisted the flag of yoga in every corner of the world, consolidated BSY into a foremost institution of yoga, and authored over eighty major texts on yoga, tantra and spiritual life.
