Some of you are probably familiar with the Yoga Niketan site. Those of you who may be interested in reading biographies of the Kriya Yoga Gurus (Yogananda, Sri Yukteswar, Lahiri Mahasaya, Babaji, Swami Kebalananda & etc.), those Master's treatises on the practice of Kriya, and their interpretation of sacred scripture in light of Kriya Yoga, this site is a shrine to that sacred path. They offer free downloads of said material and only asked that nothing be used elsewhere without permission. I'm sorry, I don't know how to make a link, but the name should get you there. Om Guru
