Mbh 7.145.1f

Janardana then quickly addressed the son of Pandu and said, “Behold, O Partha, the ruler of the Sindhus hath, by six mighty and heroic car-warriors, been placed in their-midst! Jayadratha also, O mighty-armed one, is waiting there in fear! Without vanquishing those six car-warriors in battle, O bull among men, thou wilt never be able to slay the ruler of the Sindhus even if thou exertest thyself without intermission. I shall, therefore, resort to Yoga for shrouding the sun. Then the ruler of the Sindhus will (in consequence) behold the sun to have set. Desirous of life, O lord, through joy that wicked wight will no longer, for his destruction, conceal himself. Availing yourself of that opportunity, thou shouldst then, O best of the Kurus, strike him. Thou shouldst not give up the enterprise, thinking the sun to have really set.” Hearing these words, Vibhatsu replied unto Kesava, saying, “Let it be so.” Then Krishna otherwise called Hari, possessed of ascetic powers, that lord of all ascetics, having taken recourse to Yoga, created that darkness. Thy warriors, O king, thinking the sun to have set were filled with delight at the prospect of Partha’s laying down his life. Indeed, thy warriors, not seeing the sun, were filled with gladness. All of them stood, with heads thrown backwards. King Jayadratha also was in the same attitude. And while the ruler of the Sindhus was thus beholding the sun, Krishna, once more addressing Dhananjaya said these words, “Behold, the heroic ruler of the Sindhus is now looking at the sun, casting off his fear of thee, O foremost one among the Bharatas! This is the hour, O mighty-armed one, for the slaughter of that wicked-souled wretch. Speedily cut off the head and make thy vow true.” Thus addressed by Kesava the valiant son of Pandu began to slaughter thy host with his arrows resembling the sun or fire in splendour. And he pierced Kripa with twenty arrows and Karna with fifty. And he struck Salya and Duryodhana each with six.
