Cetiya, "reminders" or "memorials", are objects and places used by Theravada Buddhists to remember Gautama Buddha. According to Damrong Rajanubhab, four kinds are distinguished in the Pāli Canon: "Relic [Dhatu], Memorial [Paribhoga], Teaching [Dhamma], and votive [Udesaka]." Griswold, in contrast, states that three are traditional and the fourth, the Buddha Dhamma, was added later to remind monks that the true memory of Gautama Buddha can be found in his teachings. While these can be broadly called Buddhist symbolism, the emphasis tends to be on a historical connection to the Buddha and not a metaphysical one.
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 .
