The footprint of the Buddha is an imprint of Gautama Buddha's foot or both feet. There are two forms: natural, as found in stone or rock, and those made artificially. Many of the "natural" ones are acknowledged not to be genuine footprints of the Buddha, but rather replicas or representations of them, which can be considered cetiya and also an early aniconic and symbolic representation of the Buddha.
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 .
