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 song that the world sings through us is to be sung into others:
Go into the world, go build cities, go discover cultures; go spread love, go give, go make magnificence, get and give light, save and join and piece together to form a whole. Gather the broken pieces, connect them; these are the things we have to work with.
Make like a map, a world where all things are linked together and murmur through each other -- a singing, a round, strong, clear song of total meaning, a language within language, responding each to each forever in the memory of each individual.
