For He can well be loved, but he cannot be thought. By love he can be grasped and held, but by thought, neither grasped nor held. And therefore, though it may be good at times to think specifically of the kindness and excellence of God, and though this may be a light and a part of contemplation, all the same, in the work of contemplation itself, it must be cast down and covered with a cloud of forgetting. And you must step above it stoutly but deftly, with a devout and delightful stirring of love, and struggle to pierce that darkness above you; and beat on that thick cloud of unknowing with a sharp dart of longing love, and do not give up, whatever happens.
