This unique edition contains a new translation of the Sutras and also a commentary by the world's leading teacher of yoga, B.K.S. Iyengar, who has enriched the text with the wealth of his own wisdom and experience of the subject. the result is an accessible, helpful book, of immense value both to students of Indian Philosophy and practitioners of yoga.
