Хатха-йога
Pre–philosophical speculations and diverse ascetic practices of first millennium BCE were systematized into a formal philosophy in early centuries CE by the "Yoga Sutras of Patanjali". By the turn of the first millennium, Hatha yoga emerged as a prominent tradition of yoga distinct from the Patanjali's "Yoga Sutras". While the "Yoga Sutras" focus on discipline of the mind, Hatha yoga concentrates on health and purity of the body.
