Yogasutras
Famous work by Patanjali (q.v.) on which is founded Yoga, one of the great systems of Indian philosophy (q.v.). It is essentially a mental discipline in eight stages (see Yoga) for the attainment of spiritual freedom without neglecting physical and moral preparation. In philosophic outlook, the sutras (q.v.) and most commentaries on them are allied to the Sankhya (q.v.), yet not without having theistic leanings. — K.F.L.
