"Think of the world you carry within you."
-- Rainer Maria Rilke
"Who could ever tire of this heart-stopping transition, this breakthrough shift between seeing and knowing you see, between being and knowing you be? It drives you to a life of concentration, it does, a life in which effort draws you down so very deep that when you surface you twist up exhilarated with a yelp and a gasp."
-- Annie Dillard
