Only one thing pleases the Lord of all: that the heart be clear of every blemish. And who is able to do this in the company of many people? Because the greater the number, the more things are thrust upon him: dreadful things, which strip and clothe with shame, which are pleasing yet pollute, which are beautiful yet disfigure. Blessed is the sense of hearing which is closed to all those things! And blessed is the heart which is empty of their memory, because in it our Sweet God reveals Himself in his Glory! (L51)
