The Yogasutras of Patañjali (200 B. C.) is the basic work of Yoga philosophy. This philosophy is one of the six systems of philosophy. This has a commentary called Vyāsabhāsya by one Vyāsa (A. D. 600). On this Vācaspati (A. D. 850) has written a learned gloss known as Tattvavaiśāradī. This is considered a standard elucidation of not only the Vyāsabhāsya but even of Yoga philosophy also.
