Akshara

Akshara () is a term used in the traditional grammar of the Sanskrit language and in the Vedanta school of Indian philosophy.

The term is derived from अ, ''a-'' "not" and क्षर्, ''kṣar-'' "melt away, perish". The uniting aspect of its use is the mystical view of language, or ''shabda'', in Hindu tradition, and especially the notion of the ''syllable'' as a kind of immutable (or "atomic") substance of both language and truth, most prominently, the mystical syllable Aum, which is given the name of ''ekākṣara'' (i.e. ''eka-akṣara''), which can be translated as both "the sole imperishable thing" and as "a single syllable".
