He may well be loved, but not thought. By love He can be caught and held, but by thinking never. Therefore, though it may be good sometimes to think particularly about God’s kindness and worth, and though it may be enlightening too, and a part of contemplation, yet in the work now before us it must be put down and covered with a cloud of forgetting. And you are to step over it resolutely and eagerly, with a devout and kindling love, and try to penetrate that darkness above you. Strike that thick cloud of unknowing with the sharp dart of longing love, and on no account whatever think of giving up.
— The Cloud of Unknowing.
