[2][4] Apaurusheya is a central concept in the Vedanta and Mimamsa schools of Hindu philosophy.
These schools accept the Vedas as svatah pramana ("self-evident means of knowledge").
The Mimamsa school asserts that since the Vedas are composed of words (shabda) and the words are composed of phonemes, the phonemes being eternal, the Vedas are also eternal.
[citation needed] To this, if asked whether all words and sentences are eternal, the Mimamsa philosophers reply that the rules behind combination of phonemes are fixed and predetermined for the Vedas, unlike other words and sentences.
