Indeed, the greatest vanity is the evil plague of empty self-glory, because it draws one away from true glory and robs one of heavenly grace. For when a man is pleased with himself he displeases You, when he pants after human praise he is deprived of true virtue. But it is true glory and holy exultation to glory in You and not in self, to rejoice in Your name rather than in one’s own virtue, and not to delight in any creature except for Your sake.
…. Thomas à Kempis , The Imitation of Christ
