How we cite our quotes:
Beauty, midnight, vision dies; (31)
Nothing lasts forever in this poem or in the world. It's not just human beings who die. Beauty doesn't last forever, nor do our visions. Even midnight "dies" every night.
Find the mortal world enough (36)
The speaker asks his sleeping beloved to be satisfied with their earthly life. He says that their world and their love are enough for both of them; they don't need a god or supernatural powers.
