Srimad Bhagavatam Canto 12, Chapter 04, Text 29

SB 12.4.29

vikarah khyayamano ’pi
 pratyag-atmanam antara
na nirupyo ’sty anur api
 syac cec cit-sama atma-vat
 
Translation: 
 
Although perceived, the transformation of even a single atom of material nature has no ultimate definition without reference to the Supreme Soul. To be accepted as factually existing, something must possess the same quality as pure spirit — eternal, unchanging existence.
 
Purport: 
 
A mirage of water appearing in the desert is actually a manifestation of light; the false appearance of water is a specific transformation of light. That which falsely appears as independent material nature is similarly a transformation of the Supreme Personality of Godhead. Material nature is the external potency of the Lord.
