Yoga (Sanskrit, Pāli: योग yóga) is a physical, mental, and spiritual discipline, originating in ancient India. The goal of yoga, or of the person practicing yoga, is the attainment of a state of perfect spiritual insight and tranquility. The word is associated with meditative practices in Hinduism, Buddhism and Jainism.Within Hindu philosophy, the word yoga is used to refer to one of the six orthodox (āstika) schools of Hindu philosophy. Yoga in this sense is based on the Yoga Sutras of Patanjali, and is also known as Rāja Yoga to distinguish it from later schools.[9] Patanjali's system is discussed and elaborated upon in many classical Hindu texts, and has also been influential in Buddhism and Jainism. The Bhagavadgita introduces distinctions such as Jnana Yoga ("yoga based on knowledge") vs. Karma Yoga ("yoga based on action").
Other systems of philosophy introduced in Hinduism during the medieval period are Bhakti Yoga, and Hatha Yoga.
The Sanskrit word yoga has the literal meaning of "yoke", from a root yuj meaning to join, to unite, or to attach. As a term for a system of abstract meditation or mental abstraction it was introduced by Patanjali in the 2nd century BC. Someone who practices yoga or follows the yoga philosophy with a high level of commitment is called a yogi or yogini.
The goals of yoga are varied and range from improving health to achieving Moksha.[14] Within the Hindu monist schools of Advaita Vedanta, Shaivism and Jainism, the goal of yoga takes the form of Moksha, which is liberation from all worldly suffering and the cycle of birth and death (Samsara), at which point there is a realization of identity with the Supreme Brahman. In the Mahabharata, the goal of yoga is variously described as entering the world of Brahma, as Brahman, or as perceiving the Brahman or Atman that pervades all things.For the bhakti schools of Vaishnavism, bhakti or service to Svayam bhagavan itself may be the ultimate goal of the yoga process, where the goal is to enjoy an eternal relationship with Vishnu.
The Sanskrit word yoga has the literal meaning of "yoke", or "the act of yoking or harnessing", from a root yuj. In Vedic Sanskrit, the term "yoga" besides its literal meaning, the yoking or harnessing of oxen or horses, already has a figurative sense, where it takes the general meaning of "employment, use, application, performance" (compare the figurative uses of "to harness" as in "to put something to some use"). All further developments of the sense of this word are post-Vedic. A sense of "exertion, endeavour, zeal, diligence" is found in Epic Sanskrit. The more technical sense of the term "yoga", describing a system of meditation or contemplation with the aim of the cessation of mental activity and the attaining of a "supreme state" arises with early Buddhism (5th century BC), and is adopted in Vedanta philosophy by the 4th century BC.
There are a great many compounds containing yoga in Sanskrit, many of them unrelated to the technical or spiritual sense the word has taken in Vedanta. Yoga in these words takes meanings such as "union, connection, contact", or "method, application, performance", etc. For example, guṇá-yoga means "contact with a cord"; cakrá-yoga has a medical sense of "applying a splint or similar instrument by means of pulleys (in case of dislocation of the thigh)"; candrá-yoga has the astronomical sense of "conjunction of the moon with a constellation"; puṃ-yoga is a grammatical term expressing "connection or relation with a man", etc.
Many such compounds are also found in the wider field of religion. Thus, bhakti-yoga means "devoted attachment" in the monotheistic Bhakti movement. The term kriyā-yoga has a grammatical sense, meaning "connection with a verb". But the same compound is also given a technical meaning in the Yoga Sutras (2.1), designating the "practical" aspects of the philosophy, i.e. the "union with the Supreme" due to performance of duties in everyday life.
