vaiśaṃpāyana uvāca |
nihataṃ pitaraṃ śrutvā dhṛtarāṣṭro janādhipaḥ |
lebhe na śāntiṃ kauravyaścintāśokaparāyaṇaḥ || 5 ||

"Vaisampayana said, 'Hearing that his sire had been slain, king Dhritarashtra of Kura's race filled with anxiety and grief, obtained no peace of mind. And while he, of Kura's race, was thus continually brooding over that sorrow, Gavalgana's son of pure soul once more came to him. Then, O monarch, Dhritarashtra, the son of Amvika, addressed Sanjaya, who had that night come back from the camp to the city called after the elephant. With a heart rendered exceedingly cheerless in consequence of his having heard of Bhishma's fall, and desirous of the victory of his sons, he indulged in these lamentations in great distress.'
