Mbh 5.161.2a

“Sanjaya said, ‘After the high-souled Pandavas, O king, had encamped by the side of the Hiranwati, the Kauravas also fixed their camps. And king Duryodhana having strongly posted his troops and paid homage to all the kings (on his side) and planted outposts and bodies of soldiers for the protection of warriors, summoned those rulers of men, viz., Karna and Dussasana and Sakuni, the son of Suvala, and began, O Bharata, to consult with them. And king Duryodhana, O Bharata, having (first) consulted with Karna, and (next), O monarch, with Karna and his (own) brother Dussasana, and Suvala’s son all together, then summoned, O bull among men, Uluka and bringing him into his presence in private, told him, O king, these words, “O Uluka, O son of an adept at dice, repair thou unto the Pandavas and the Somakas. And repairing thither, repeat these my words (unto Yudhishthira) in the hearing of Vasudeva. That terrible battle between the Kurus and the Pandavas which had been expected from a long time back has at last come. Those boastful words which Sanjaya brought to me, in the midst of the Kurus and which thou hadst, with Vasudeva and thy younger brothers, uttered in deep roar,--the time, O son of Kunti, hath at last come for making them good. Do ye achieve, therefore, all which ye have pledged yourselves to achieve. Unto the eldest son of Kunti thou must say, as my words, the following, ‘Virtuous as thou art, how canst then, with all thy brothers, with the Somakas, and the Kekayas, set thy heart upon unrighteousness? How canst thou wish the destruction of the universe, when, as I think thou shouldst be the dispeller of the fears of all creatures. O bull of Bharata’s race, this sloka sung of old by Prahlada when his kingdom had been wrested from him by the gods, hath been heard by us,--Ye gods, that person whose standard of righteousness is always up, but whose sins are always concealed is said to adopt the behaviour of the cat (in the story).’
