Arjuna at once strode forward, fully armed, and he was supported by Drona and Bhishma. Duryodhana and his band stood by Karna. Then the two warriors prepared for single combat, but not in mimic warfare. Thick clouds gathered in the sky; lightning flashed and thunder pealed; the mighty Indra guarded his son Arjuna, who stood in shadow. Surya, the sun god, cast a shaft of light athwart the darkening plain, and Karna's golden armour gleamed bright and fair. The noble dames looked on, and some praised Arjuna and others praised Karna. Pritha, the mother of both heroes, was alone divided in her love. She knew her firstborn by his voice and noble bearing and by his armour, and her heart was torn with grief to behold the two brothers ready to slay each other. A cloud blinded her eyes, and, uttering a low cry, she swooned where she sat. Vidura sprinkled water on her face, and she was revived. Then she wept bitterly because that she could not reveal the secret of Karna's birth. Kripa,[232] the foster-brother of Bhishma, performed the duties of herald, and as Arjuna strode forth to combat he proclaimed: “Behold! this is mighty Arjuna, of Bharata's great line, son of Pandu and of Pritha, a prince of valour and worth who will not shrink from battle. Unknown and long-armed chief,” he said unto Karna, “declare now thy name and lineage, the royal house thou dost adorn, and the names of thy sire and thy mother. Know thou that by the rules of single combat the sons of kings cannot contend against low-born or nameless rivals.” [232] Kripa, like Drona, was of miraculous birth. He and his sister were found in a forest, and were adopted by King Shantanu. Karna heard, but was silent. He hung his head like the dew-laden lotus bloom; he could claim nor lineage or high rank, as he believed, for he regarded the charioteer of Anga as his sire. Duryodhana, perceiving his discomfiture, cried out to Kripa, saying: “Valour is not reckoned by birth but by deeds. Karna hath already shown himself to be the peer of princes. I now proclaim him the Rajah of Anga.” Having spoken thus, the elder of the Kauravas led Karna by the hand and placed him upon a throne, and the red umbrella was held above his head. Brahmans chanted the texts for the ceremony and anointed Karna as a king. Then the fan was waved and the royal umbrella raised on high, while the Kauravas shouted: “The rajah is crowned; blessings on the rajah; honour to the valorous warrior!” Robed in royal attire, Karna then spake to Duryodhana and said: “With generous heart thou hast conferred upon me a kingdom. O prince, speak and say what service thou wouldst have me to render unto thee.” Said Duryodhana: “But one boon do I ask of thee, O king. Be my comrade and, O valiant warrior, be my helper also.” Karna said: “As thou desirest, so be it.” Then Duryodhana and Karna embraced one another to confirm their loyal friendship.
