Translation: 

 

I think You are the Supreme Personality among the three chief gods, since You drive away the darkness of this cave as a lamp dispels darkness with its light.

 

Purport: 

 

Srila Visvanatha Cakravarti points out that with His effulgence Lord Krsna dispelled not only the darkness of the mountain cave but also the darkness in Mucukunda’s heart. In Sanskrit the heart is sometimes metaphorically referred to as guha, “cavern,” a deep and secret place.
