Luther on going to sleep at night

"At night always carry in your heart something from Holy Scriptures to bed with you, meditate upon it like a ruminant animal, and go softly to sleep; but this must not be too much, rather a little that may be well pondered and understood, that you may find a remnant of it in your mind when you rise in the morning."

(P.S. See Christina's post on sleep, which begins "Sleeping is incredibly boring".)
