A saint is a person who practices the keystone human virtue of humility. Humility in the face of wealth and plenty, humility in the face of hatred and violence, humility in the face of strength, humility in the face of your own genius or lack of it, humility in the face of another's humility, humility in the face of love and beauty, humility in the face of pain and death. Saints are driven to humbling themselves before all the splendor and horror of the world because they perceive there to be something divine in it pulsing and alive beneath the hard dead surface of material things -- greater and purer than they are.
Those who neglect silence bring only a distracted heart and a preoccupied mind to their prayer and, instead of deriving new strength from it, they only offer God a heart full of trifles. Intimate conversation with God is easily stifled if you do not first put an end to exterior chatter; yet, if you love silence and keep it well, your heart will be a temple where God will dwell and become known to you there.
