Srimad-Bhagavatam: Canto 11 - Chapter 1 - Verse 28


एवमन्वीक्षमाणस्य कथं वैकल्पिको भ्रमः । मनसो हृदि तिष्ठेत व्योम्नीवार्कोदये तमः ॥ २८ ॥


evam anvīkṣamāṇasyakathaṁ vaikalpiko bhramaḥmanaso hṛdi tiṣṭhetavyomnīvārkodaye tamaḥ


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.


Just as the brilliant sun removes all darkness from the sky, a clear understanding of the knowledge spoken by Lord Kṛṣṇa 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.
