# Yoga Sutra

The yoga sutras of Patañjali (IAST: Patañjali yoga-sūtra) is a compilation "from a variety of sources" of Sanskrit sutras (aphorisms) on the practice of yoga – 195 sutras (according to Vyāsa and Krishnamacharya) and 196 sutras (according to others, including BKS Iyengar). The yoga sutras were compiled in India in the early centuries CE by the sage Patanjali, who collected and organized knowledge about yoga from Samkhya, Buddhism, and older Yoga traditions, and possibly another compiler who may have added the fourth chapter. He may also be the author of the Yogabhashya, a commentary on the yoga sutras, traditionally attributed to the legendary Vedic sage Vyasa, but possibly forming a joint work of Patanjali called the Pātañjalayogaśāstra.
