It is a central tenet of all major Indian religions, namely Buddhism, Hinduism, Jainism, and Sikhism. The human idea of reincarnation is found in many diverse ancient cultures, and a belief in rebirth/metempsychosis was held by historic Greek figures, such as Pythagoras and Plato. It is also a common belief of various ancient and modern religions such as Spiritism, theosophy, and Eckankar. It is found as well in many tribal societies around the world, in places such as Australia, East Asia, Siberia, and South America.

Unity Church and its founder Charles Fillmore teach reincarnation.
