Mbh 8.87.1f

Thus all creatures were interested in that encounter, siding with this or that leader of car-warriors, the Kuru or the Pandava hero. Beholding the Self-born Lord of Creation (viz., Brahman), the gods urged him, saying, "Let, O god, the success of these two lions among men be equal. Let not the vast universe be destroyed in consequence of this encounter between Karna and Arjuna. O Selfborn one, say but the word, let the success of these two be equal." Hearing these words, Maghavat, bowing down unto the Grandsire, represented this unto that god of gods, that foremost one of all intelligent beings, saying, "Formerly it was said by thy holy self that the two Krishnas are always sure to win victory. Let it be (now) as thou then saidest. Be gratified with me, O holy one!" At this, Brahman and Isana replied unto the chief of the celestials, saying, "The victory of the high-souled Vijaya is certain, of that Savyasaci who gratified the eater of sacrificial libations in the forest of Khandava and who, coming to heaven, rendered assistance to thee, O Sakra! Karna is on the side of the Danavas. It is proper, therefore, that he should meet with defeat. By this, without doubt, the purposes of the gods will be achieved. One's own business, O chief of the celestials, should always be important. The high-souled Phalguna, again, is devoted to truth and to morality. He must always be victorious, without doubt. He by whom the high-souled and holy god having the bull on his standard was gratified, why should not he, O thou of a hundred eyes, be victorious,--he, that is, who hath for the driver of his car that Lord of the universe, Vishnu himself? Possessed of great energy of mind and great strength, Partha is a hero, accomplished in arms and endued with ascetic merit. Possessed also of great energy of body, he beareth the entire science of weapons. Indeed, Partha hath every accomplishment. He ought to be victorious, since that would accomplish the purposes of the gods.
