Parāçara said:—Having said this, Kesava, assuming human shape summoned mentally the deity of the wind, who immediately came there, and said to him—"Proceed, Vāyu, to Indra and tell him to lay aside his pomp, and resign to Ugrasena his splendid hall Sudharman: tell him that Krishna commands him to send the royal hall, the unrivalled gem of princely courts, for the assemblage of the race of Yādu". Accordingly Vāyu went and delivered the message to the husband of Sachi, who immediately gave up to him the hall Sudharman, and Vāyu conveyed it to the Yādavas, the chiefs of whom thenceforth possessed this celestial court, emblazoned with jewels, and defended by the arms of Govinda. The two excellent Yadu youths, versed in all knowledge, and possessed of all wisdom, then submitted to instruction, as the disciples of teachers. Accordingly they repaired to Sāndipani—who, though born in Kāsi, resided at Avanti—to study the science of arms, and, becoming his pupils, were obedient and attentive to their master, exhibiting an example to all men of the observance of instituted rules. In the course of sixty-four days they had gone through the elements of military science, with the treatises on the use of arms, and directions for the mystic incantations, which secure the aid of supernatural weapons. Sāndipani, astonished at such proficiency, and knowing that it exceeded human faculties, imagined that the sun and the moon had become his scholars. When they had acquired all that he could teach, they said to him, "Now say what present shall be given to you, as the preceptor's fee". The prudent Sāndipani, perceiving that they were endowed with more than mortal powers, requested them to give him his dead son, drowned in the sea of Prabhāsa. Taking up their arms, they marched against the ocean; but the all-comprehending sea said to them, "I have not killed the son of Sāndipani; a demon named Panchajana, who lives in the form of a conch shell, seized the boy; he is still under my waters". On hearing this, Krishna plunged into the sea; and having slain the vile Panchajana, he took the conch shell, which was formed of his bones (and bore it as his horn), the sound of which fills the demon hosts with dismay, animates the vigour of the gods, and annihilates unrighteousness. The heroes also recovered the boy from the pains of death, and restored him in his former person to his father. Rāma and Janārddana then returned to Mathura, which was well presided over by Ugrasena, and abounded in a happy population both of men and women.
