The teachings of Self-Realization Fellowship/Yogoda Satsanga Society of India are founded upon the original Christianity of Jesus Christ and the original Yoga of Bhagavan Krishna. The spiritual lineage of SRF/YSS consists of these two great avatars and a line of exalted masters of contemporary times: Mahavatar Babaji, Lahiri Mahasaya, Swami Sri Yukteswar, and Paramahansa Yogananda (last in the line of SRF/YSS Gurus).
Each of these Great Ones played a role in Self-Realization Fellowship's mission of bringing to the modern world the spiritual science of Kriya Yoga.
The passing of a guru's spiritual mantle to a disciple designated to carry on the lineage to which that guru belongs is termed guru-parampara. Thus, Paramahansa Yogananda's direct lineage of gurus is Mahavatar Babaji, Lahiri Mahasaya, and Swami Sri Yukteswar.
All members of Self-Realization Fellowship (monastics as well as lay members) who have taken the sacred initiation in Kriya Yoga are disciples of Paramahansa Yogananda. He is given respect and devotion as their personal guru, and his lineage of Gurus is likewise venerated by SRF disciples.
