11.26.2

yā tvaṃ putraṃ durātmānamīrṣumatyantamāninam |
duryodhanaṃ puraskṛtya duṣkṛtaṃ sādhu manyase || 2 ||

"The holy one said, ‘Arise, arise, O Gandhari, do not set thy heart on grief! Through thy fault, this vast carnage has taken place! Thy son Duryodhana was wicked-souled, envious, and exceedingly arrogant. Applauding his wicked acts, thou regardest them to be good. Exceedingly cruel, he was the embodiment of hostilities, and disobedient to the injunctions of the old. Why dost thou wish to ascribe thy own faults to me? Dead or lost, the person that grieves for what has already occurred, obtaineth more grief. By indulging in grief, one increases it two-fold. A woman of the regenerate class bears children for the practice of austerities; the cow brings forth offspring for bearing burdens; the mare brings forth her young for acquiring speed of motion; the Shudra woman bears a child for adding to the number of servitors; the Vaishya woman for adding to the number of keepers of cattle. A princess, however, like thee, brings forth sons for being slaughtered!’"
