Yogasūtra

Patañjali.

The Yoga Sutras of Patañjali (Sanskrit: पतञ्जलि योगसूत्रम्, romanised: Patañjali yogasūtram) 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.
