"Active asceticism operates within the world; rationally active asceticism, in mastering the world, seeks to tame what is creatural and wicked through work in a worldly "vocation" (inner-worldly asceticism). Such asceticism contrasts radically with mysticism, if the latter draws the full conclusion of fleeing from the world (contemplative flight from the world). The contrast is tempered, however, if active asceticism confines itself to keeping down and to overcoming creatural wickedness in the actor's own nature. For then it enhances the concentration on the firmly established God-willed and active redemptory accomplishments to the point of avoiding any action in the orders of the world (asceticist flight from the world). Thereby active asceticism in external bearing comes close to contemplative flight from the world. The contrast between asceticism and mysticism is also tempered if the contemplative mystic does not draw the conclusion that he should flee from the world, but, like the inner-worldly asceticist, remain in the orders of the world (inner-worldly mysticism). In both cases the contrast can actually disappear in practice and some combination of both forms of the quest for salvation may occur. But the contrast may continue to exist even under the veil of external similarity. For the true mystic the principle continues to hold: the creature must be silent so that God may speak."
