Srimad-Bhagavatam: Canto 12 - Chapter 1 - Verse 48

Sanskrit:

सङ्कीर्त्यमानो भगवाननन्त:श्रुतानुभावो व्यसनं हि पुंसाम् ।प्रविश्य चित्तं विधुनोत्यशेषंयथा तमोऽर्कोऽभ्रमिवातिवात: ॥ ४८ ॥

ITRANS:

saṅkīrtyamāno bhagavān anantaḥśrutānubhāvo vyasanaṁ hi puṁsāmpraviśya cittaṁ vidhunoty aśeṣaṁyathā tamo ’rko ’bhram ivāti-vātaḥ

Translation:

When people properly glorify the Supreme Personality of Godhead or simply hear about His power, the Lord personally enters their hearts and cleanses away every trace of misfortune, just as the sun removes the darkness or as a powerful wind drives away the clouds.

Purport:

One may not be satisfied by the example of the sun removing the darkness, since sometimes the darkness in a cave is not removed by the sun. Therefore the example is given of a strong wind that drives away a cover of clouds. It is thus emphatically stated here that the Supreme Lord will remove from the heart of His devotee the darkness of material illusion.
