Kriya Yoga is an ancient technique that was hidden in secrecy for many centuries. It was revived in 1861, when the great yogi Mahavatar Babaji taught the technique to his disciple Lahiri Mahasaya during their meeting in the Himalayas.
Kriya has been taught in an unbroken link of spiritual succession to this day. Paramhansa Yogananda personally authorized his disciple, Swami Kriyananda (founder of Ananda) to initiate qualified people into Kriya.
