Yoga is in religion, but religion is not in Yoga. The principles of Yoga are (in alphabetical order) in Buddhism, Christianity, Hinduism, Islam, Jainism, Judaism, Sikhism, and most of the other religions. However, unlike religions, Yoga itself has no deity, worship services, rituals, sacred icons, creed, confession, clergy, institutions, congregation, membership procedure, or system of temples or churches. The word “Yoga” means “union” referring to the direct experience of the wholeness of ourselves at all levels.
