svaṁ svaṁ vyasyann anekadhā
śiṣyaiḥ praśiṣyais tac-chiṣyair
vedās te śākhino ’bhavan
The original source of knowledge is the Vedas. There are no branches of knowledge, either mundane or transcendental, which do not belong to the original text of the Vedas. They have simply been developed into different branches. They were originally rendered by great, respectable and learned professors. In other words, the Vedic knowledge, broken into different branches by different disciplic successions, has been distributed all over the world. No one, therefore, can claim independent knowledge beyond the Vedas.
