[{"role": "system", "content": "Yoga (; Sanskrit, \u092f\u094b\u0917\u0903 Listen) is a group of physical, mental, and spiritual practices or disciplines which originated in ancient India. There is a broad variety of yoga schools, practices, and goals in Hinduism, Buddhism, and Jainism. Among the most well-known types of yoga are Hatha yoga and R\u0101ja yoga. The origins of yoga have been speculated to date back to pre-Vedic Indian traditions; it is mentioned in the Rigveda, but most likely developed around the sixth and fifth centuries BCE, in ancient India's ascetic and \u015brama\u1e47a movements. The chronology of earliest texts describing yoga-practices is unclear, varyingly credited to Hindu Upanishads. The \"Yoga Sutras of Patanjali\" date from the first half of the 1st millennium CE, but only gained prominence in the West in the 20th century. Hatha yoga texts emerged around the 11th century with origins in tantra. Yoga gurus from India later introduced yoga to the West, following the success of Swami Vivekananda in the late 19th and early 20th century. In the 1980s, yoga became popular as a system of physical exercise across the Western world. Yoga in Indian traditions, however, is more than physical exercise; it has a meditative and spiritual core.\n"}, {"role": "assistant", "content": "Yoga is a group of physical mental, and spiritual practices.
