Reincarnation, also known as rebirth or transmigration, is the philosophical or religious concept that the non-physical essence of a living being begins a new life in a different physical form or body after biological death. Resurrection is a similar process hypothesized by some religions, in which a soul comes back to life in the same body. In most beliefs involving reincarnation, the soul is seen as immortal and the only thing that becomes perishable is the body. Upon death, the soul becomes transmigrated into a new infant (or animal) to live again. The term transmigration means passing of soul from another body to another after-death.
