" There is another reason also why the soul has traveled safely in this obscurity; it has suffered: for the way of suffering is safer, and also more profitable, than that of rejoicing and of action. In suffering God gives strength, but in action and in joy the soul does but show its own weakness and imperfections. And in suffering, the soul practices and acquires virtue, and becomes pure, wiser, and more cautious. "

― John of the Cross , Dark Night of the Soul
