A disciple of Yajnavalkya, who was well-versed in all sacrificial rites and who was a complete master of the Vedas, proceeded with Partha for performing auspicious rites in favour of the hero. Many Brahmanas also, O king, all well-conversant with the Vedas, and many Kshatriyas too, followed the high-souled hero, at the command, O monarch, of Yudhishthira the just. The horse then roamed, O foremost of men, wherever he liked over the Earth already conquered by Pandavas with the energy of their weapons. In course of the horse's wanderings, O king, many great and wonderful battles were fought between Arjuna and many kings. These I shall describe to thee. The horse, O king, roamed over the whole Earth. Know, O monarch, that from the north it turned towards the East. Grinding the kingdoms of many monarchs that excellent horse wandered. And it was followed slowly by the great car-warrior Arjuna of white steeds. Countless, O monarch, was the fete of Kshatriyas,--of kings in myriads--who fought with Arjuna on that occasion, for having lost their kinsmen on the geld of Kurukshetra. Innumerable [paragraph continues] Kiratas also, O king, and Yavanas, all excellent bowmen, and diverse tribes of Mlechechas too, who had been discomfited before (by the Pandavas on the field of Kurukshetra), and many Aryan kings, possessed of soldiers and animals endued with great alacrity, and all irresistible in fight encountered the son of Pandu in battle.
