Buddhism developed in India, and is based on many of the core concepts of Hinduism.. Buddhists believe in an endless cycle of reincarnation, or samsara, which is similar to beliefs of Hinduism. However, Buddhists do not believe that deities are responsible for the phenomenon. In addition, the Caste System is rejected by Buddhists who believe instead that one is reincarnated until they can achieve nirvana, best described as spiritual enlightenment.
