The fourfold division of castes was created by me according to the apportionment of qualities and duties. But though I am its author, know me to be inexhaustible, and not the author. Actions defile me notI have no attachment to the fruit of actions. He who knows me thus is not tied down by actions. Knowing this, the men of old who wished for final emancipation, performed action. Therefore do you, too, perform action as was done by men of old in olden times.
