Artículo "sarîra" (reliquia) en Wikipedia

Śarīra (शरीर) are generic terms for "Buddhist relics", although in common usage these terms usually refer to a kind of pearl or crystal-like bead-shaped objects that are purportedly found among the cremated ashes of Buddhist spiritual masters. Sarira are held to emanate or incite 'blessings' and 'grace' (Sanskrit: adhishthana) within the mindstream and experience of those connected to them.[1] Sarira are also considered apotropaic in the Himalayan tradition.

Terminology
The term sarira or "sharira" (शरीर) is a loanword from Sanskrit. The term "Sarira" originally means "body" in Sankrit, but when used in Buddhist Sanskrit texts to mean "relics", it is always used in the plural: śarīrāḥ. The term ringsel is a loanword from the Tibetan language. Both of these terms are somewhat ambiguous in English, they are generally used as synonyms, although according to some interpretations, ringsels are a subset of sariras.

Sarira can refer to:

• Dharma body sariras, or sutras as told by the Buddha, according to Din Fu Bao's Dictionary of Buddhist Terms, a Dharma body sasira is "the Sutra as told by the Buddha: That which is unchanging in what is told by the Buddha, is of the same property as the essence of the Buddha himself, hence it is called the 'dharma body sarira'".
• Corporal and full body sariras, the cremated remains of the Buddha (or any other spiritual master), but can also be used to refer other remains (for instance, a finger), or a preserved body, similar to the Roman Catholic incorruptibles. Full body sariras refers to the mummified remains of spiritual masters.
• Broken body sariras refers specifically to cremated remains.
• Sariras or Ringsels, when used without qualification, the term sarira generally refers to the pearl-like remnant of a master after cremation.
  
  The word "shrine" is sometimes used as a translation for ringsels (e.g. heart shrine relic refers to ringsels that supposedly formed from someone's heart.) This rather peculiar use of the term "shrine" reflects the Buddhist concept of shrine. For Buddhists, a shrine is anything that is deliberately constructed to remind one of something that is essentially intangible. Ringsels, whose primary function is to act as a memento, serves the same purpose as shrines, hence it is referred to as such.
