The Vedanta Sutras of Badarayana, Commentary by Sankara (SBE38), tr. by George Thibaut  at sacred-texts.com
14. Or else the permission (of works) is for the glorification (of knowledge).
The passage 'Performing works here' may be treated in another way also. Even if, owing to the influence of the general subject-matter, only he who knows is to be viewed as he who performs works, yet the permission to perform works must be viewed as aiming at the glorification of knowledge; as appears from the subsequent clause, 'no work clings to the man.' The meaning of the entire passage thus is: To a man who knows no work will cling, should he perform works during his whole life even, owing to the power of knowledge. And this clearly glorifies knowledge.
