Light on the Yoga Sutras of Patanjali

From the world's greatest and best-known teacher of yoga comes this guide to the discipline. Patanjali, an early Indian sage and mystic, was the first to systematize and codify the principle and practice of yoga. Patanjali's collection of 185 aphorisms, "Yoga Sutras", remains the classical work on the subject - this book provides a commentary on Patanjali's work.
