Sūtra translation
But on account of enhancement by works of the fruit of knowledge being spoken of (in Scripture), Badaray ana’s judg- ment is such (i.e., only from knowledge all things are obtained) i for that is observed (to be a fad) and declared in Scripture.
This is seen from the Kauntharavya Sruti which says, “ From knowledge only, svarga is obtained; from know- ledge only, release is obtained; from knowledge only, all the desires become accomplished ; still according as the individual does good works, he becomes greater (i.e., he becomes the receptacle of enhanced bliss). In the case of Yudhisthira and others, enhanced fruit is observed to be the result of the performance of Rajasuya and other sacrifices; hence is the judgment of Badarayana.
