Yoga (Sanskrit, yóga) refers to traditional physical and mental disciplines originating in India. The word is associated with meditative practices in Hinduism, Buddhism and Jainism. In Hinduism, it also refers to one of the six orthodox schools of Hindu philosophy, and to the goal toward which that school directs its practices.
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 or yogini.
Aum (also Om), is a mystical or sacred syllable in the Indian religions which originated from Hinduism.
