Kriya Yoga is already mentioned as a method in the Yoga Sutras of Rishi Patanjali and has become known through the “Autobiography of a Yogi” by Paramahansa Yogananda. The Kriya Yoga technique involves a combination of body, breathing, concentration, and meditation practices that promote comprehensive (physical, mental, and spiritual) development.
“Kri” means action or action and “Ya” is the soul. The practice of Kriya Yoga is to perform all actions in unity with the (divine) soul at all times and places. The soul (Atma) is formless, all-pervading, conscious force or energy that receives all life through breathing. The true nature of the soul is SAT – CIT – ANANDA, eternal, timeless BEING; all-conscious, all-pure BEING; all-happy joy in BEING.
Kriya Yoga can not be learned from books. Only an experienced teacher who has achieved at least the fourth Kriya can pass it on to students.
