sankirtyamano bhagavan anantah
srutanubhavo vyasanam hi pumsam
pravisya cittam vidhunoty asesam
yatha tamo ’rko ’bhram ivati-vatah
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.
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.
