Srimad Bhagavatam Canto 10, Chapter 14, Text 57

SB 10.14.57

sarvesam api vastunam
bhavartho bhavati sthitah
tasyapi bhagavan krsnah
kim atad vastu rupyatam
 
Translation: 
 
The original, unmanifested form of material nature is the source of all material things, and the source of even that subtle material nature is the Supreme Personality of Godhead, Krsna. What, then, could one ascertain to be separate from Him?
