In plain words
The whiteness of the night lilies is kindled only by the moon's light; moonlight itself comes about only when evening arrives; the full clarity of a fresh pearl is seen only after polishing. The brightness of Kāmākṣī's smile shines by its own nature.
Word for word
Whiteness of lily-beauties by the moon's light only is kindled; the moonlight-lustre too the evening-time having reached only comes about; clarity of a new pearl highest from polishing is seen; of Kāmākṣī of the smile-rays the brightness natural shines.
