Purport: 

Taking the proper position from which to describe the dynasty of Manu, Śukadeva Gosvāmī begins by saying that when the entire world is inundated, only the Supreme Personality of Godhead exists, and nothing else. Śukadeva Gosvāmī will now describe how the Lord creates other things, one after another.
