People cannot become perfect by dint of hearing or reading about perfection. The chief thing is not to listen to yourself, but silently to listen to God. Talk little and do much, without caring to be seen. God will teach you more than all the most experienced persons or the most spiritual books can do. You already know a great deal more than you practise. You do not need the acquirement of fresh knowledge half so much as to put in practice that which you already possess.
