Srimad Bhagavatam Canto 11, Chapter 24, Text 28

SB 11.24.28

evam anviksamanasya
 katham vaikalpiko bhramah
manaso hrdi tistheta
 vyomnivarkodaye tamah
 
Translation: 
 
Just as the rising sun removes the darkness of the sky, similarly, this scientific knowledge of cosmic annihilation removes all illusory duality from the mind of a serious student. Even if illusion somehow enters his heart, it cannot remain there.
 
Purport: 
 
Just as the brilliant sun removes all darkness from the sky, a clear understanding of the knowledge spoken by Lord Krsna to Uddhava removes all ignorance concocted by the material mind. One will then no longer accept the material body as the self. Even if such illusion temporarily manifests within one’s consciousness, it will be driven away by the resurgence of one’s spiritual knowledge.
