Srimad-Bhagavatam: Canto 11 - Chapter 1 - Verse 34
Sanskrit:
यथा हि भानोरुदयो नृचक्षुषांतमो निहन्यान्न तु सद् विधत्ते ।एवं समीक्षा निपुणा सती मेहन्यात्तमिस्रं पुरुषस्य बुद्धे: ॥ ३४ ॥
ITRANS:
yathā hi bhānor udayo nṛ-cakṣuṣāṁtamo nihanyān na tu sad vidhatteevaṁ samīkṣā nipuṇā satī mehanyāt tamisraṁ puruṣasya buddheḥ
Translation:
When the sun rises it destroys the darkness covering men’s eyes, but it does not create the objects they then see before them, which in fact were existing all along. Similarly, potent and factual realization of Me will destroy the darkness covering a person’s true consciousness.
