In plain words
Your forehead shines so purely with loveliness that the crescent in your crown seems its matching half. One curve faces the other; meeting along a line of nectar, they complete a radiant full moon.
Close to the Sanskrit
Your forehead, pure with beauty's lustre, shines; I take the crescent set in your crown to be its second half. Placed in reverse, the two meet one another, joined by a seam of nectar-paste, and become the full moon.
