Designed expressly for the serious practitioner of yoga, this is an outstanding work of scholarship that is eminently practical, even to those students who have no previous familiarity with the Yoga Sutras. This volume includes an overview of Sankya-yoga and an extensive Glossary/Index. For each sutra, a word-by-word translation is supplied, followed by Vyasa's commentary and then the author's discussion, which presents the views of previous pre-eminent commentators.
