narasya ca yathātattvaṃ yanmāṃ tvaṃ paripṛcchasi |
yadarthaṃ nṛṣu saṃbhūtau naranārāyaṇāvubhau || 13 ||

Sanjaya continued, "Hearing this sacred story, thy son, O great king, began to regard highly both Kesava and these mighty car-warriors, viz., the sons of Pandu. Then, O monarch, Bhishma the son of Santanu once more addressed thy son, saying, 'Thou hast now heard truly, O king, about the glory of the high-souled Kesava and of Nara about which thou hadst asked me. Thou hast also heard about the object for which both Nara and Narayana have taken their births among men. Thou hast also been told the reason why those heroes are invincible and have never been vanquished in battle, and why also, O king, the sons of Pandu are incapable of being slain in battle, by anybody. Krishna beareth great love for the illustrious sons of Pandu. It is for this, O king of kings, that I say, 'Let peace be made with the Pandavas.' Restraining thy passions enjoy thou the Earth with thy mighty brothers (around thee). By disregarding the divine Nara and Narayana, thou shalt certainly be destroyed. Having said these words, thy sire, became silent, O monarch, and dismissing the king, entered his tent. And the king also came back to his (own) tent, having worshipped the illustrious grandsire. And then, O bull of Bharata's race, he laid himself down on his white bed for passing the night in sleep."
