Yantra Yoga or the Yoga of Movement, is one of the oldest recorded systems of Yoga that exists in the world. It is a system of Yoga that has come to us through Tibet, a land full of a vast and rich traditional Buddhist knowledge and wisdom. Chögyal Namkhai Norbu has written an extensive commentary on the root teachings by Vairocana from the 8th century, Nyida Khajor, the Union of Sun and Moon Yantra, based on his personal training and knowledge of Yantra Yoga received from his uncle and various teachers in Tibet. Chögyal Namkhai Norbu began teaching Yantra Yoga in the beginning of the 70's in Italy.
