Paramahansa Yogananda
Paramahansa Yogananda (January 5, 1893 – March 7, 1952), a disciple of Swami Sri Yukteswar, and guru of Roy Eugene Davis, brought the teachings of Kriya Yoga to the West in 1920. He founded Self-Realization Fellowship, initiated thousands into Kriya Yoga, and published study lessons and books. His most famous book is Autobiography of a Yogi.
Self-realization is the knowing—in body, mind, and soul—that we are one with the omnipresence of God; that God’s omnipresence is our omnipresence; that we are just as much a part of God now as we ever will be. All we have to do is improve our knowing. I never allow the word “impossible” to take root in my mind; nor should you.
