Purva Mimamsa approaches the Vedas as an eternal and authorless revelation, described as *apauruṣeya* and *nitya*. They are not regarded as the work of any human or even a personal deity, but as self-existent and independent of temporal origin. Because of this authorlessness, the Vedas are held to be infallible and free from the limitations and defects that characterize human cognition, such as error, ignorance, or deception. Their words and sentences are seen as beginningless realities that are manifested in each cosmic cycle rather than created anew. This vision grants the Vedas a unique ontological status among sources of knowledge.

From this standpoint, the Vedas are considered *svataḥ-pramāṇa* or intrinsically valid, not requiring any external justification or corroboration. Their authority is self-grounded, and doubts about their reliability are traced to misunderstanding rather than to any flaw in the texts themselves. Within this framework, the Vedas function as the supreme and indeed sole source for knowledge of *dharma*, especially in the sense of ritual duty and right action. What is to be done, what is obligatory, and what leads to unseen results cannot be fully known through perception or inference; it is disclosed only through Vedic revelation.

Purva Mimamsa therefore reads the Vedas primarily as a body of injunctions, a collection of commands and prescriptions oriented toward action. The focus falls on the *karma-kāṇḍa*—the ritual sections such as the Saṃhitās and Brāhmaṇas—rather than on speculative or philosophical passages. Narrative and descriptive portions are treated as subordinate, serving mainly to support, clarify, or motivate the ritual injunctions that they accompany. The Vedic sentences that enjoin sacrifice and other rites are taken to be the heart of the text, for they delineate concrete duties and their subtle, often unseen, consequences.

In this ritual-centered vision, the Vedic word itself possesses a distinctive power when correctly uttered and enacted. The sounds of the mantras, as *śabda*, are not merely symbolic but are bound up with the efficacy of the sacrifice and the realization of *dharma*. The authority of the Vedas thus expresses itself not only in doctrinal content but in the very performance of Vedic rites, where precise recitation and adherence to injunction become the means by which the eternal, authorless revelation shapes human life and destiny.
