Mbh 5.142.1a

“Sanjaya said, ‘Hearing these words of Karna, Kesava, that slayer of hostile heroes, spoke unto him these words smilingly, “Do not the means of winning an empire recommend themselves to thee, O Karna? Wishest thou not to rule over the whole earth given by me to thee? The victory of the Pandavas, therefore, is very certain. There seems to be no doubt in this. The triumphal banner of Pandu’s son, with the fierce ape on it, seems to be already set up. The divine artificer, Bhaumana, hath applied such celestial illusion (in its construction) that it standeth high, displayed like Indra’s banner. Various celestial creatures of terrific shape, indicating victory, are seen on that standard. Extending for a yojana upwards and all around, that beautiful standard of Arjuna, resembling fire in radiance, is never, O Karna, when set up, obstructed by hills or trees. When thou wilt behold in battle Arjuna, on his car drawn by white steeds and driven by Krishna, applying Aindra, Agneya and Maruta weapons, and when thou wilt hear the twang of Gandiva piercing the welkin like the very thunder, then all signs of the Krita, the Treta, and the Dwapara ages will disappear (but, instead, Kali embodied will be present). When thou wilt behold in battle Kunti’s son, invincible Yudhishthira, devoted to Yapa and Homa and resembling the very sun in brilliance, protecting his own mighty army and burning the army of his foes, then all signs of the Krita, the Treta, and the Dwapara ages will disappear. When thou wilt behold in battle the mighty Bhimasena dancing, after having quaffed the blood of Dussasana, like a fierce elephant with rent temples after having killed a mighty antagonist, then all signs of the Krita, the Treta, and the Dwapara ages will disappear.
