Iyengar developed a form of yoga that focuses on developing strength, endurance, correct body alignment, as well as flexibility and relaxation. The Iyengar method integrates philosophy, spirituality, and the practice of yoga into everyday living. In The Tree of Yoga, Iyengar offers his thoughts on many practical and philosophical subjects including family life, love and sexuality, health and the healing arts, meditation, death, and Pata jali's Yoga Sutras. This new edition features a foreword by Patricia Walden, a leading American teacher of the Iyengar style.
