Śukadeva Gosvāmī said: My dear King, I have already described to you the measurements of time, beginning from the smallest fraction measured by the movement of a single atom up to the total life span of Lord Brahmā. I have also discussed the measurement of the different millennia of universal history. Now hear about the time of Brahmā’s day and the process of annihilation.
