Warning that the original spiritual wisdom of Yoga could be lost as Hatha Yoga's popularity grows in the West, the author of Living Yoga and other Yoga texts reveals the depths of meaning beneath the postures and breathing techniques. A full nine-hour curriculum covers the true history of Yoga and its many branches, the virtues and disciplines that flower into enlightenment, subtle anatomy and the energy of prana, or life-force, the origins of the postures, and much more.
