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.
"What makes one wise?" asked the disciple.
"Wisdom," replied the Master.
"What is wisdom?" was retorted.
"It is simply the ability to recognize," said the Master.
"To recognize what?" the disciple asked.
"Spiritual wisdom," the Master answered, "is the power to recognize the butterfly in a caterpillar, the eagle in an egg, the saint in the sinner."
"Only a silent mind is capable of this recognizing power."
