Ask not of me, love, what is love?
Ask what is good of God above;
Ask of the great sun what is light;
Ask what is darkness of the night;
Ask sin of what may be forgiven;
Ask what is happiness of heaven;
Ask what is folly of the crowd;
Ask what is fashion of the shroud;
Ask what is sweetness of thy kiss;
Ask of thyself what beauty is.
