Yoga 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. The ultimate goal of Yoga is moksha(liberation), although the exact definition of what form this takes depends on the philosophical or theological system with which it is conjugated.

According to Jacobsen, “Yoga has five principal meanings:

1. Yoga, as a disciplined method for attaining a goal;
2. Yoga, as techniques of controlling the body and the mind;
3. Yoga, as a name of one of the schools or systems of philosophy (darśana);
4. Yoga, in connection with other words, such as “hatha-, mantra-, and laya-,” referring to traditions specialising in particular techniques of yoga;
5. Yoga, as the goal of Yoga practice.
