The Yoga Sutra is the first and most important book ever written on yoga. It was composed in Sanskrit by the Indian master Patanjali about seventeen hundred years ago. All modern yoga schools, including Ashtanga, Iyengar, Bikram, Anusara, and Tibetan Heart Yoga, accept the Sutra as the highest source. It is a book that every yoga teacher and practitioner should read and use as a guide for yoga and life. This new translation and commentary allows you to effortlessly apply the Sutra to your own yoga practice. It is precise and clear, based on more than one hundred early Indian and Tibetan manuscripts that have not been available in German until now. Geshe Michael Roach and Christie McNally have spent over twenty-five years in Asia during this time.
