Death is one of the few certainties in life. Every person experiences it in some way (including their own), and very often, will take part in a ritual surrounding the end of a loved one's life. Many similarities exist among historical death traditions, but there is no single way to grieve, express loss, or celebrate a person's life. Whether it's how a group prepares a corpse, shows continued deference and care for a deceased loved one, or honors the legacy of a fallen hero, death rituals reveal a lot about living. As a result, the end of life has been met with cultural practices and religious rites through the ages.
