The first principle

Though you shall have read and learned many things, it will always be necessary for you to return to this one principle: I am He who teaches man knowledge, and to the little ones I give a clearer understanding than can be taught by man. He to whom I speak will soon be wise and his soul will profit. But woe to those who inquire of men about many curious things, and care very little about the way they serve Me.Thomas à Kempis, The Imitation of Christ
