Pha That Luang is a gold-covered large Buddhist stupa in the centre of the city of Vientiane, Laos. Since its initial establishment, suggested to be in the 3rd century AD, the stupa has undergone several reconstructions as recently as the 1930s due to foreign invasions of the area. It is generally regarded as the most important national monument in Laos and a national symbol.
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 .
