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.
