SB 1.4.23, Translation and Purport:

All these learned scholars, in their turn, rendered their entrusted Vedas unto their many disciples, grand-disciples and great grand-disciples, and thus the respective branches of the followers of the Vedas came into being.

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, divided into different branches, has been distributed all over the world by different disciplic successions. No one, therefore, can claim independent knowledge beyond the Vedas.
