Yoga : Yoga (Sanskrit, Pali: yoga) refers to traditional physical and mental disciplines originating in India.[1] The word is associated with meditative practices in Buddhism and Hinduism.[2][3] In Hinduism, it also refers to one of the six orthodox (astika) schools of Hindu philosophy, and to the goal towards which that school directs its practices.[4][5] In Jainism it refers to the sum total of all activities—mental, verbal and physical.
Raja Yoga, compiled in the Yoga Sutras of Pathanjali, and known simply as yoga in the context of Hindu philosophy, is part of the Samkhya tradition.[9] Many other Hindu texts discuss aspects of yoga, including Upanishads, the Bhagavad Gita, the Hatha Yoga Pradipika, the Shiva Samhita and Thirumoolar.
The Sanskrit word yoga has many meanings, and is derived from the Sanskrit root yuj, meaning "to control", "to yoke" or "to unite".Translations include "joining", "uniting", "union", "conjunction", and "means". Outside India, the term yoga is typically associated with Hatha Yoga and its asanas (postures) or as a form of exercise. Someone who practices yoga or follows the yoga philosophy is called a Yogi. Pathanjali's writing also became the basis for a system referred to as "Ashtanga Yoga" ("Eight-Limbed Yoga"). This eight-limbed concept derived from the 29th Sutra of the 2nd book, and is a core characteristic of practically every Raja yoga variation taught today.
