Georg Feuerstein Ph.D. (Author) Approximately two thousand years old, The Yoga-Sutra of Patañjali is the landmark scripture on classical yoga. The translation and commentary provided here by Georg Feuerstein are outstanding for their accessibility and their insight into the essential meaning of this ancient and complex text. A scholar of international renown who has studied and practiced yoga since the age of fourteen, Feuerstein also brings to The Yoga-Sutra of Patañjali his experience as a professional indologist. His faithful and informed rendering of the aphorisms (sutras) is based on extensive personal research into the Sanscrit sources. Each word is explained so that the entire text becomes readily available to the western reader and student of yoga.
