Thou hast already been recognised by the celestials and the celestial sages of high soul.' Thereupon I said unto Sakra, 'O divine one, be thou favourable unto me. With the view of learning arms do I beseech thee that thou mayst 'be my preceptor.' At this Indra said, 'O child, having learnt weapons thou wouldst perform terrible deeds and with this object thou desirest to obtain the weapons. However, obtain thou the arms, as thou desirest.' Then I said, 'O slayer of foes, I never would discharge these celestial weapons at mortals except when all my other arms should have been baffled. Do thou, O lord of the celestials, grant me the celestial weapons (so that) I may hereafter, obtain the regions attainable by warriors.' Indra said, 'O Dhananjaya it is to try thee that I have said such words unto thee. Having been begotten of me this speech of thine well becometh thee. Do thou, O Bharata, repairing unto my abode learn all the weapons of Vayu, of Agni, of the Vasus, of Varuna, of the Marutas, of the Siddhas, of Brahma, of the Gandharvas of the Uragas, of the Rakshasas, of Vishnu and of the Nairitas; and also all the weapons that are with me, O perpetuator of the Kuru race.' Having said this unto me Sakra vanished at the very spot. Then, O king, I saw the wonderful and sacred celestial car yoked with steeds arrive conducted by Matali. And when the Lokapalas went away Matali said unto me. 'O thou of mighty splendour, the lord of the celestials is desirous of seeing thee.
