“His slight smiling and fragrant illumination are compared to camphor, which enters the sweetness of the lips. That sweetness is transformed and enters into space as vibrations from the holes of His flute.
“The sound of Kṛṣṇa’s flute spreads in four directions. Even though Kṛṣṇa vibrates His flute within this universe, its sound pierces the universal covering and goes to the spiritual sky. Thus the vibration enters the ears of all inhabitants. It especially enters Goloka Vṛndāvana-dhāma and attracts the minds of the young damsels of Vrajabhūmi, bringing them forcibly to where Kṛṣṇa is present.
“The vibration of Kṛṣṇa’s flute is very aggressive, and it breaks the vows of all chaste women. Indeed, its vibration takes them forcibly from the laps of their husbands. The vibration of His flute attracts even the goddesses of fortune in the Vaikuṇṭha planets, to say nothing of the poor damsels of Vṛndāvana.
“The vibration of His flute slackens the knots of their underwear even in front of their husbands. Thus the gopīs are forced to abandon their household duties and come before Lord Kṛṣṇa. In this way all social etiquette, shame and fear are vanquished. The vibration of His flute causes all women to dance.
“The vibration of His flute is just like a bird that creates a nest within the ears of the gopīs and always remains prominent there, not allowing any other sound to enter their ears. Indeed, the gopīs cannot hear anything else, nor are they able to concentrate on anything else, not even to give a suitable reply. Such are the effects of the vibration of Lord Kṛṣṇa’s flute.”
