The Yoga Sutras of Patanjali

The Yoga Sutras of Patañjali is a collection of Sanskrit sutras (aphorisms) on the theory and practice of yoga - 195 sutras (according to Vyāsa and Krishnamacharya) and 196 sutras (according to other scholars including BKS Iyengar). The Yoga Sutras was compiled in the early centuries CE, by the sage Patanjali in India who synthesized and organized knowledge about yoga from much older traditions.The Yoga Sutras are best known for its reference to ashtanga, eight elements of practice culminating in samadhi, concentration of the mind on an object of meditation, namely yama (abstinences), niyama (observances), asana (yoga postures), pranayama (breath control), pratyahara (withdrawal of the senses), dharana (concentration of the mind), dhyana (meditation) and samadhi (absorption). However, its main aim is kaivalya, discernment of purusha, the witness-conscious, as separate from prakriti, the cognitive apparatus, and disentanglement of purusha from prakriti's muddled defilements. The Yoga Sutras built on Samkhya-notions of purusha and prakriti, and are often seen as complementary to it. It is closely related to Buddhism, incorporating some of its terminology. Yet, Samkhya, Yoga, Vedanta, as well as Jainism and Buddhism can be seen as representing different manifestations of a broad stream of ascetic traditions in ancient India, in contrast to the Bhakti traditions and Vedic ritualism which were prevalent at the time. The contemporary Yoga tradition holds the Yoga Sutras of Patañjali to be one of the foundational texts of classical Yoga philosophy. However, the appropriation - and misappropriation - of the Yoga Sutras and its influence on later systematizations of yoga has been questioned by David Gordon White, who argues that the text fell into relative obscurity for nearly 700 years from the 12th to 19th century, and made a comeback in late 19th century due to the efforts of Swami Vivekananda, the Theosophical Society and others. It gained prominence as a classic in the 20th century.
