Srimad Bhagavatam Canto 09, Chapter 01, Text 08

SB 9.1.8

paravaresam bhutanam
 atma yah purusah parah
sa evasid idam visvam
 kalpante ’nyan na kiñcana
 
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
The transcendental Supreme Person, the Supersoul of all living entities, who are in different statuses of life, high and low, existed at the end of the millennium, when neither this manifested cosmos nor anything else but Him existed.
 
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
Taking the proper position from which to describe the dynasty of Manu, Sukadeva Gosvami begins by saying that when the entire world is inundated, only the Supreme Personality of Godhead exists, and nothing else. Sukadeva Gosvami will now describe how the Lord creates other things, one after another.
