Mahabharata Aswamedha Parva Chapter 72

Mahabharata Aswamedha Parva (Anugita Parva) Chapter 72 Vaisampayana said, 'Thus addressed by Krishna, Yudhishthira, the son of Dharma, endued with great intelligence, saluted Vyasa and said these words: "Do thou cause me to be initiated when the proper hour, as thou truly knowest, comes for that rite. This my sacrifice is entirely dependent on thee. Vyasa said, "Myself, O son of Kunti, and Paila and Yajnavalkya, shall without doubt, achieve every rite at the proper time. The rite of initiating thee will be performed on the day of full moon belonging to the month of Chaitra. Let all the necessaries of the sacrifice, O foremost of men, be got ready. Let Sutas well-versed in the science of horses, and let Brahmanas also possessed of the same lore, select, after examination, a worthy horse in order that thy sacrifice may be completed. Loosening the animal according to the injunctions of the scriptures, let him wander over the whole Earth with her belt of seas, displaying thy blazing glory, O king! Vaisampayana continued, 'Thus addressed (by the Rishi), Yudhishthira, the son of Pandu, that lord of Earth, answered,—"So be it!"—and then, O monarch, he accomplished all that that utterer of Brahma had directed. All the articles necessary for the sacrifice, O king, were duly procured. The royal son of Dharma, possessed of immeasurable soul, having procured all the necessaries, informed the Island-born Krishna of it. Then Vyasa of great energy said unto the royal son of Dharma,—"As regards ourselves, we are all prepared to initiate thee in view of the sacrifice. Let the Sphya and the Kurcha and all the other articles that, O thou of Kuru's race, may be needed for thy sacrifice, be made of gold. Let the horse also be loosened today, for roaming on the Earth, agreeably to the ordinances of the scriptures. Let the animal, duly protected, wander over the Earth.
