I do not know how much nectar the two syllables ‘Krs-na' have produced. When the holy name of Krsna 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.

(Vidagdha-madhava 1.15, quoted in Sri Caitanya-caritamrta, Antya-lila 1.99)
