Relic

In religion, a relic usually consists of the physical remains of a saint or the personal effects of the saint or venerated person preserved for purposes of veneration as a tangible memorial. Relics are an important aspect of some forms of Buddhism, Christianity, Hinduism, Shamanism, and many other religions. Relic derives from the Latin reliquiae, meaning "remains," and a form of the Latin verb relinquere, to "leave behind, or abandon." A reliquary is a shrine that houses one or more religious relics.
