Lord Kṛṣṇa offered homage to Himself in this boundless form, and Arjuna, astonished at the sight of Lord Mahā-Viṣṇu,
bowed down as well. Then, as the two of them stood before Him with joined palms, the almighty Mahā-Viṣṇu,
supreme master of all rulers of the universe, smiled and spoke to them in a voice full of solemn authority.
[Lord Mahā-Viṣṇu said:] I brought the brāhmaṇa’s sons here because I wanted to see the two of you, My expansions,
who have descended to the earth to save the principles of religion. As soon as you finish killing the demons
who burden the earth, quickly come back here to Me.
Although all your desires are completely fulfilled, O best of exalted personalities, for the benefit of the
people in general you should continue to exemplify religious behavior as the sages Nara and Nārāyaṇa.
Thus instructed by the Supreme Lord of the topmost planet, Kṛṣṇa and Arjuna assented by chanting om,
and then they bowed down to almighty Lord Mahā-Viṣṇu. Taking the brāhmaṇa’s sons with them, they
returned with great delight to Dvārakā by the same path along which they had come. There they
presented the brāhmaṇa with his sons, who were in the same infant bodies in which they had been lost.
