Reincarnation is the belief that when one dies, one's soul is reborn in a new body. This is a central tenet of Hinduism and Buddhism and is also found in other religions and tribal societies. There are debates around what exactly is reincarnated - the soul? consciousness? The majority of Abrahamic religions like Christianity and Islam do not believe in reincarnation, seeing life as linear with an afterlife, rather than cyclical rebirth.
