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.
The first peace, which is the most important, is that which comes within the souls of people when they realize their relationship, their oneness, with the universe and all its powers, and when they realize that at the center of the universe dwells the Great Spirit, and that this center is really everywhere, it is within each of us.
