You look into a mirror so that you may know what is in your face, whether there are any blemishes in it, and having seen blemishes, you cleanse them. Let the immaculate life of Christ be a mirror to your soul. Does it desire the same things that Christ desires? And does it do what Christ did when He lived on earth? And in it you will see what is contrary to the life of Christ, and you will cleanse it all like blemishes with repentance and contrition of heart.
