Sariputra and Mahamoggallana were the two chief disciples of Gautama Buddha, and died within two weeks of one another, after which they were cremated and their relics kept. After a period, the relics were lost to civilisation.
Śarīra is a generic term referring to Buddhist relics, although in common usage it usually refers to pearl or crystal-like bead-shaped objects that are purportedly found among the cremated ashes of Buddhist spiritual masters.
Relics of the Buddha after cremation are termed dhātu in the Mahaparinibbana Sutta.
Śarīra are held to emanate or incite 'blessings' and 'grace' within the mindstream and experience of those connected to them.
Sarira are also believed to ward off evil .
