Translation
After one day of Brahmā, annihilation occurs during his night, which is of the same duration. At that time all the three planetary systems are subject to destruction. [Note: At the beginning of Brahmā’s night, the planets including Svarga are flooded. Later all the planets and Brahmā enter into Viṣṇu.]
Tāvat means one thousand cycles of four yugas.
