Yoga (/ˈjoʊɡə/;[1] Sanskrit: योग; ISO: Yōga , About this soundpronunciation), Sanskrit for yoking or union, is a group of physical, mental, and spiritual practices or disciplines that originated in ancient India. Yoga is one of the six orthodox philosophical schools of Hinduism.[2][3] There are a broad variety of yoga schools, practices, and goals[4] in Hinduism, Buddhism, and Jainism[5][6][7] and there are four paths or types of yoga: Karma yoga, Kriya yoga, Bhakti yoga, and Jnana yoga.[8] Research studies have shown that traditional yoga systems that include breathing exercises and asanas or postures, chants, and meditation can reduce stress and improve immunity and lung functions.[9] Traditional forms and modern methods of yoga are practiced worldwide.[10]The practice of yoga has been thought to date back to pre-vedic Indian traditions, possibly in the Indus valley civilization around 3000 BCE. Yoga is mentioned in the Rigveda,[note 1] and also referenced in the Upanishads,[12] though it most likely developed as a systematic study around the 5th and 6th centuries BCE, in ancient Indias ascetic and Śramaṇa movements.[13][note 2] The chronology of earliest texts describing yoga practices is unclear, varyingly credited to the Upanishads.[14] The Yoga Sutras of Patanjali date from the 2nd century BCE,[15][16] and gained prominence in the West in the 20th century after being first introduced by Swami Vivekananda.[17] Hatha yoga texts began to emerge sometime between the 9th and 11th century with origins in tantra.[18][19]Yoga gurus from India introduced yoga to the West following the success of Vivekanandas adaptation of yoga without asanas in the late 19th and early 20th centuries.[4] The term yoga in the Western world often denotes a modern form of hatha yoga and yoga as exercise, consisting largely of the asanas.[20] Outside India, it has developed into a posture-based physical fitness, stress-relief and relaxation technique.[21] Traditional yoga, however, includes physical exercise, meditation, and spirituality.[21][22] Yoga has its own epistemological method, which assumes the ontology and metaphysics of the closely correlated Samkhya darsana.
