Wisdom of Saint Jean-Marie Vianney

"You must close your heart against pride, sensuality, and all other such unruly passions, just as one shuts doors and windows so that none may enter. Thus, when going along the street, let us fix our heart and eyes on our Lord bearing His Cross before us, or the Blessed Virgin who is looking upon us, or our Angel Guardian who is ever by our side."

--Saint Jean-Marie Vianney, from his Catechesis on purity and the control of the eyes.
