brāhmo naimittiko layaḥ
lokā bhūr-ādayo nṛpa
āsīt — there was; atīta — past; kalpa-ante — at the end of the kalpa; brāhmaḥ — of Lord Brahmā’s day; naimittikaḥ — because of that; layaḥ — inundation; samudra — in the ocean; upaplutāḥ — were inundated; tatra — there; lokāḥ — all the planets; bhūḥ-ādayaḥ — Bhūḥ, Bhuvaḥ and Svaḥ, the three lokas; nṛpa — O King.
O King Parīkṣit, at the end of the past millennium, at the end of Brahmā’s day, because Lord Brahmā sleeps during the night, annihilation took place, and the three worlds were covered by the water of the ocean.
