Humility.

Brown, Jesus Washing Peter's Feet (detail), 1856

Humility is the mother of all virtues; purity, charity and obedience. It is in being humble that our love becomes real, devoted and ardent. If you are humble nothing will touch you, neither praise nor disgrace, because you know what you are. If you are blamed you will not be discouraged. If they call you a saint you will not put yourself on a pedestal.

Mother Teresa
