21 June 2020 is International Yoga Day. Recognizing its universal appeal, on 11 December 2014, the United Nations proclaimed 21 June as the International Day of Yoga by resolution 69/131.
According to US National Institutes of Health, yoga may help one to feel more relaxed, be more flexible, improve posture, breathe deeply, and get rid of stress. According to an estimate, about 21 million Americans, including many celebrities, now practice yoga. Yoga is the repository of something basic in the human soul and psyche.
Yoga is an Indian physical, mental, and spiritual practice or discipline. There is a broad variety of schools, practices and goals in Hinduism, Buddhism (including Vajrayana and Tibetan Buddhism) and Jainism. The best-known are Hatha yoga and Raja yoga.
The origins of Yoga have been speculated to date back to pre-Vedic Indian traditions, but most likely developed around the sixth and fifth centuries BCE, in ancient India’s ascetic circles, which are also credited with the early sramana movements. The chronology of earliest texts describing yoga-practices is unclear, varyingly credited to Hindu Upanishads and Buddhist Pāli Canon, probably of third century BCE or later. The Yoga Sutras of Patanjali from first half of 1st millennium CE is one of a key surviving major texts on Yoga. Hatha yoga texts emerged around 11th century CE, and in its origins was related to Tantrism.
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. One of the six major orthodox schools of Hinduism is also called Yoga, which has its own epistemology and metaphysics, and is closely related to Hindu Samkhya philosophy.
