The traditions of Hinduism, especially the Vedanta sampradāyas, have developed elaborate and sophisticated arguments for the words of the Vedas as a source of valid knowledge. This study seeks to explicate this rationale, with particular attention to the tradition of Advaita Vedanta. The understanding of scripture as a valid source of knowledge (pramāṇa) is neglected in the contemporary study of Hinduism, although this approach may lend a fresh perspective to the meaning and significance of sacred texts and a unique way of understanding their authority. Scripture cannot claim exemption from being subject to the same criteria that are utilized to validate other ways of knowing. Scripture as pramāṇa is a Hindu argument that enriches our understanding of sacred texts and ought to be a prominent point of view in the contemporary discussion of the nature and authority of scripture.
