The term for a vigil held over a deceased person originates from historical practices related to ensuring the individual was truly dead before burial. This practice involved observing the body, sometimes for an extended period, to detect any signs of returning to life. The purpose was to prevent premature burial in an era when medical diagnosis was less precise.
The historical necessity of confirming death gave rise to customs centered around the body. These gatherings served not only a practical purpose but also allowed family and friends to mourn and pay their respects. Over time, the observation period evolved into a social and religious event, becoming a significant part of mourning rituals in various cultures.
