tāndṛṣṭvā yādavānāha paśyadhvamatidāruṇān /
mahotpātāñchamāyaiṣāṃ prabhāsaṃ yāma mā ciram //

The mighty Krishńa now beheld signs and portents both in earth and heaven, prognosticating, day and night, the ruin of Dwáraká. Shewing these to the Yádavas, he said, "See; behold these fearful phenomena: let us hasten to Prabhása, to avert these omens." When he had thus spoken to the eminent Yádava, the illustrious Uddhava saluted and said to him, "Tell me, O lord, what it is proper that I should do, for it seems to me that thou wilt destroy all this race: the signs that are manifest declare nothing less than the annihilation of the tribe." Then Krishńa replied to him, "Do you go by a celestial route, which my favour shall provide you, to the holy place Badarikáśrama, in the Gandhamádana mountain, the shrine of Naranáráyańa; and on that spot, sanctified by them, thou, by meditating on me, shalt obtain perfection through my favour. When the race of Yadu shall have perished, I shall proceed to heaven; and the ocean shall inundate Dwáraká, when I have quitted it." Accordingly Uddhava, thus instructed by Keśava, saluted him with veneration, and departed to the shrine of Naranáráyańa.
