Shankara’s Commentary:
Com.—You, though repeatedly tempted by me, have renounced objects of desires, such as sons, etc., and also objects of sweet shape, such as nymphs, judging well of them and ascertaining their faults, i.e., their ephemeral and sapless nature. Oh Nachiketas, how intelligent you are! You have not taken up this contemptible path of wealth, trodden by the ignorant men, in which many fools come to grief.
