In plain words
The curling tips of its wave-like brows threaten old age. Made of nectar, white and shining, lord of the rivers — I bow.
Close to the Sanskrit
By the curving of the tips of the brow-frowns that are its waves, it threatens old age. To the one made of nectar, to the bright one, to the lord of rivers — salutation.
