Those who are acquainted with the Vedas are said to be of two sorts, viz., those who lecture on the Vedas and those who are otherwise. Of these the former, who are wellread in the Vedas, and are conversant with the duties and the rites laid down in them, and the fruits of those duties and rites, are superior for their declaring all those duties and rites. Indeed, all the Vedas, with the duties laid down in them, are said to emanate from them.
वेदज्ञानि द्वयान्याहुः प्रवक्तृणीतराणि च। प्रवक्तणि विशिष्टानि सर्वधर्मोपधारणात्॥ विज्ञायन्ते हि यैर्वेदाः सधर्माः सक्रियाफला:। सधर्मा निखिला वेदाः प्रवक्तृभ्यो विनिःसृताः॥
