We know of no happiness that has ever come to us from you, for you have given yourself over to the vice of gambling with dice. Having yourself brought about this calamity, O son of Pāṇḍu, you now assail us today with harsh and cutting words.

Educational Q&A

The verse condemns gambling as a destructive vyasana (ruinous vice) and insists on moral accountability: one who causes a disaster through one’s own addiction cannot justly blame others or speak harshly as if wronged.

The speaker rebukes a Pāṇḍava addressee for being devoted to dice-play and for having personally brought about a calamity; despite that, the addressee is now speaking severe, accusatory words to the speaker’s side.
