 Mimamsa philosophers believed that the revelation of the Vedas was sacred, authorless ("apaurusheyatva") and infallible, and that it was essential to preserve the sanctity of the Vedic ritual to maintain dharma (cosmic order).As a consequence of the belief in sanctity of the ritual, Mimamsas rejected the notion of God in any form.Later commentators of the Mimamsa sutras such as Prabhākara (c. 7th century CE) advanced arguments against the existence of God.
