Humility is the foundation of all the other virtues hence, in the soul in which this virtue does not exist there cannot be any other virtue except in mere appearance.
Late have I loved you, O beauty ever ancient, ever new. Late have I loved you. You have called to me, and have called out, and have shattered my deafness. You have blazed forth with light and have put my blindness to flight! You have sent forth fragrance, and I have drawn in my breath, and I pant after you. I have tasted you, and I hunger and thirst after you. You have touched me, and I have burned for your peace.
Do you know who the upright of heart are? They are those who wish what God wishes. Therefore, do not try to twist God's will to you own but correct your will to that of God. The will of God is a rule of conduct. By it you have the means of being converted and of correcting your evil ways.
Do you wish to be great? Then begin by being. Do you desire to construct a vast and lofty fabric? Think first about the foundations of humility. The higher your structure is to be, the deeper must be its foundation.
