hiraṇyapuraghātaṃ ca māyānāṃ ca nivāraṇam |
nivātakavacānāṃ ca vadhaṃ saṃkhye mahaujasām || 63 ||

And that city of Danavas, in appearance like unto the city of the Gandharvas filled with lamentations and stricken with dole and distress, and bereft of grace even like unto a lake deprived of (its) elephants, or like unto a forest deprived of trees and (deprived of its) masters, looked no longer beautiful--but it vanished, like a cloud-constructed city. And when I had accomplished the task, eftsoons from the field Matali took me of delighted spirits, unto the abode of the lord of the celestials. And having slain those mighty Asuras, and destroyed Hiranyapura, and having also killed the Nivata-Kavachas, I came unto Indra. And, O exceedingly resplendent one, as it had fallen out, Matali related in detail unto Devendra that entire achievement of mine. And with the Marutas, hearing of the destruction of Hiranyapura, of the neutralisation of the illusion, and of the slaughter of the highly powerful Nivatakavachas in fight, the prosperous thousand-eyed divine Purandara was well pleased, and exclaimed, 'Well done; Well done!' And the king of the celestials together with the celestials, cheering me again and again, said these sweet words, 'By thee hath been achieved a feat incapable of being achieved by the gods and the Asuras. And, O Partha, by slaying my mighty enemies, thou hast paid the preceptor's fee.
