A Sri Lankan friend of mine told me that Buddha’s ear is a cherished relic there. She showed me a picture of a religious procession, with elephants, that is held annually, and the ear leads off the parade, apparently.
About a year ago I read about the relics of Buddha, evidently one had been stolen (Burma, now Myanmar) and it made the news,
I asked the Abbot of the local Buddhist temple if these relics of Buddha’s body actually existed and he told me yes they did and explained that they were incisor teeth, because teeth sometimes survive cremation. He told me there were 4 of them and they were stored in 4 different temples, never together, in case something ever happened to one of the temples. I know the Abbot, because my wife is the temple’s bookkeeper and, although I’m not Buddhist myself, I get sucked into their fund raiser events regularly.
