Vishnupurana 3.6.p6

3.6.p6

I have thus related to you the various branches of the Vedas and their sub-divisions, the persons by whom they made and the object with which they were ushered into existence. Such was the division in all the Manwantaras. The primitive Veda, which was instituted by Brahmā at the beginning of Kalpa, is eternal; these branches are but its modifications.
