Srimad Bhagavatam Canto 10, Chapter 14, Text 27

SB 10.14.27

tvam atmanam param matva
param atmanam eva ca
atma punar bahir mrgya
aho ’jña-janatajñata
 
Translation:
 
Just see the foolishness of those ignorant persons who consider You to be some separated manifestation of illusion and who consider the self, which is actually You, to be something else, the material body. Such fools conclude that the supreme soul is to be searched for somewhere outside Your supreme personality.
 
Purport: 
 
Lord Brahma is amazed at the gross ignorance of conditioned souls who consider Lord Krsna’s supreme spiritual body to be material. Ignorant of the spiritual form of the Lord, such persons also consider their own material bodies to be the self, and therefore they conclude that spiritual reality is to be found somewhere beyond the supreme personality of Lord Krsna. Sometimes such fools consider Lord Krsna to be one of many individual souls who together constitute a single impersonal spiritual entity. Unfortunately, such speculators are not inclined to hear from the Lord Himself or from the Lord’s authorized representatives, such as Lord Brahma. Because they whimsically speculate on the nature of the Supreme, their ultimate result is confusion and ignorance, which they euphemistically describe as “the mystery of life.”
