"Vaisampayana said, 'When the hour for initiation came, all those great Ritwijas duly initiated the king in view of the horse-sacrifice. Having finished the rites of binding the sacrificial animals, the son of Pandu, viz., king Yudhishthira the just endued with great energy, the initiation being over, shone with great splendour along with those Ritwijas. The horse that was brought for the horse-sacrifice was let loose, agreeably to the injunctions of the scriptures, that utterer of Brahma, viz., Vyasa himself of immeasurable energy. The king Yudhishthira the just, O monarch, after his initiation, adorned with a garland of gold around his neck, shone in beauty like a blazing fire. Having a black deer skin for his upper garment, bearing a staff in hand, and wearing a cloth of red silk, the son of Dharma, possessed of great splendour, shone like a second Prajapati seated on the sacrificial altar. All his Ritwijas also, O king, were clad in similar robes. Arjuna also shone like a blazing fire. Dhananjaya, unto whose car were yoked white steeds, then duly prepared, O king, to follow that horse of the complexion of a black deer, at the command of Yudhishthira. Repeatedly drawing his bow, named Gandiva, O king, and casing his hand in a fence made of iguana skin, Arjuna, O monarch, prepared to follow that horse, O ruler of men, with a cheerful heart.
