Which Bone Is the Relic, and Who Says So

Of the four bone relics recovered from the Famensi crypt in 1987, Buddhist tradition and the temple's own presentation identify one, kept innermost within a nested sequence of jewelled caskets, as the genuine finger bone of the Buddha, and the other three as replicas made to accompany and protect it, following the documented Tang-dynasty practice of guarding sacred relics with decoy versions. This is a claim of religious authenticity rather than one that scientific testing can adjudicate, since there is no independent method for verifying that any bone belonged to a historical individual identified as the Buddha centuries after his death; the museum and the Buddhist organisations associated with the temple present the identification as a matter of transmitted faith, resting on the crypt's own Tang-period inventory rather than on forensic proof.

What is not in dispute is the material context: the accompanying stone inventory, itself found in the crypt, lists the relic and treasures by name and links them to the documented ninth century imperial dedication, giving the deposit a firmer archaeological anchor than most relic traditions receive. The relic has since travelled internationally under temple and government sponsorship for veneration by overseas Buddhist communities, a modern echo of the Tang practice of processing it to the capital, and its custody remains jointly a religious and a state heritage matter in China, where major Buddhist sites operate under government cultural heritage oversight alongside monastic administration.
