A yogi (sometimes spelled jogi) is a practitioner of yoga. In Vedic Sanskrit, yoga (from the root yuj) means to add, to join, to unite, or to attach in its most common literal sense, where in recent days, especially in the West, yoga often refers to physical exercises only. The term yogi is used broadly to refer to sannyasi or practitioners of meditation in a number of Indian religions. The feminine form is yogini, but is not always used, especially in the West.Yogi, or jogi, since the 12th century CE, while meaning those dedicated to Yoga practice, has also referred to members of the Nath siddha tradition of Hinduism. Alternatively, in tantra traditions of Hinduism, Buddhism and Jainism, a practitioner of tantra (a tantrika) may also be called a yogi. In Hindu mythology, god Shiva and goddess Parvati are depicted as an emblematic yogi–yogini pair.
