Most religions have something to say about death, however, as with much else, there is no consistent message provided by all religions.
Religions disagree on such basic notions as when an individual is truly dead.
We suppose this happens at a discrete time. Other traditions see death as a process. Where this is true there are frequently traditions of secondary burial. Body buried once at what we call death, and a second time after the decomposition of the flesh. Practice of endocannibalim to recapture the remaining spirit and keep it within the group.
