yudhiṣṭhira uvāca |
naitaccitraṃ mādhava yadbravīṣi satyaṃ tu me rakṣyatamaṃ na rājyam |
kṛṣṇastu māṃ veda yathāvadekaḥ kṛṣṇaṃ ca vedāhamatho yathāvat || 26 ||

"Yudhishthira said, 'It is not strange that thou shouldst speak thus, O scion of Madhu's race! but to me truth seems to be the first consideration, above that of my sovereign power itself. But it is Krishna alone who precisely knoweth what I am; and it is I alone who precisely know what Krishna (really) is. O thou endued with valour! O scion of Madhu's race! as soon as he will perceive that the time is come for feats of bravery, then, O most valiant of Sini's race, he also of beautiful hair (Krishna) will defeat Suyodhana. Let the brave men of the Dasarha race go back today. They are my patrons; and the foremost of human beings, they have visited me here. O ye of immeasurable strength! never fall off from the path of virtue. I shall see you again, when ye will be happily gathered together.'
