tunde tandavini ratim vitanute tundavali-labdhaye
karna-kroda-kadambini ghatayate karnarbudebhyah spriham
cetah-prangana-sangini vijayate sarvendriyanam kritim
no jane janita kiyadbhir amritaih krishneti varna-dvayi
I do not know how much nectar the two syllables 'Krish-na' have produced. When the holy name of Krishna is chanted, it appears to dance within the mouth. We then desire many, many mouths. When that name enters the holes of the ears, we desire many millions of ears. And when the holy name dances in the courtyard of the heart, it conquers the activities of the mind, and therefore all the senses become inert.
This verse is included in the Vidagdha-madhava (1.15), a seven-act play written by Srila Rupa Gosvami describing the pastimes of Sri Krishna in Vrindavana.
