CC Madhya 21.138
tāte yei mukha sudhākara
madhura haite sumadhura, tāhā ha-ite sumadhura,
tāra yei smita jyotsnā-bhara
kṛṣṇa-aṅga — the bodily features of Kṛṣṇa; lāvaṇya-pūra — the city of attractive beauty; madhura — sweetness; haite — than; su-madhura — still more sweet; tāte — in that body; yei — that; mukha — face; sudhākara — like the moon; madhura haite su-madhura — sweeter than sweetness; tāhā ha-ite — than that; su-madhura — still more sweet; tāra — of which; yei — that; smita — smiling; jyotsnā-bhara — like the moonshine.
“Kṛṣṇa’s body is a city of attractive features, and it is sweeter than sweet. His face, which is like the moon, is sweeter still. And the supremely sweet gentle smile on that moonlike face is like rays of moonshine.
The smile on Kṛṣṇa’s face, which is just like the smiling of the moon, generates greater and greater happiness for the gopīs.
