Maṇi

maṇi (T. nor bu; C. moni/zhu; J. mani/shu; K. mani/chu 摩尼/珠). A jewel, gem, precious stone (e.g. a pearl), etc.

In Buddhist texts, the term maṇi commonly appears as a generic term for a precious gem, and is used "in descriptions of the heavens and pure lands and figuratively as a metaphor for something beautiful, precious, and rare."

The term appears in compounds such as cintāmaṇi (“wish-fulfilling jewel”) and the famous mantra, om mani padme hum. "In this mantra and elsewhere, the term is particularly associated with the bodhisattva Avalokiteśvara."
