The premiere volume of Thupten Jinpa's thirty-two-volume Library of Tibetan Classics series, inaugurated to coincide with the Dalai Lama's conferral of the initiation rite of Kalacakra in Toronto in April 2004.
The Kalacakra, or "wheel of time," tantra likely entered Indian Mahayana Buddhism around the tenth century. In expounding the root tantra, the Indian master Pundarika, one of the legendary Kalki kings of the land of Shambhala, wrote his influential Stainless Light. Ornament of Stainless Light is an authoritative Tibetan exposition of this important text, composed in the fifteenth century by Khedrup Norsang Gyatso, tutor to the Second Dalai Lama.
One of the central projects of Kalacakra literature is a detailed correlation between the human body and the external universe. In working out this complex correspondence, the Kalacakra texts present an amazingly detailed theory of cosmology and astronomy, especially about the movements of the various celestial bodies. The Kalacakra tantra is also a highly complex system of Buddhist theory and practice that employs vital bodily energies, deep meditative mental states, and a penetrative focus on subtle points within the body's key energy conduits known as channels. Ornament of Stainless Light addresses all these topics, elaborating on the external universe, the inner world of the individual, the Kalacakra initiation rites, and the tantric stages of generation and completion, all in a highly readable English translation.
