2.52.16

na cākāmaḥ śakuninā devitāhaṃ na cenmāṃ dhṛṣṇurāhvayitā sabhāyām |
āhūto'haṃ na nivarte kadācittadāhitaṃ śāśvataṃ vai vrataṃ me || 16 ||

"Yudhishthira said,--'It would seem then that some of the most desperate and terrible gamblers always depending upon deceit are there. This whole universe, however, is at the will of its Maker, under the control of fate. It is not free. O learned one, I do not desire, at the command of king Dhritarashtra to engage myself in gambling. The father always wisheth to benefit his son. Thou art our master, O Vidura. Tell me what is proper for us. Unwilling as I am to gamble, I will not do so, if the wicked Sakuni doth not summon me to it in the Sabha? If, however, he challengeth me, I will never refuse. For that, as settled, is my eternal vow."
