Frederick Franck turned to the door of the building, a massive wooden sculpture in the form of the sun and its rays, and pushed it open. I saw that it turned on a central axis, so that only one half of the door was open at any one time. To remind us, he murmured, that we step into this sacred space as we walk into life, alone and silently . . . I looked around me and marveled at this ninety-year-old man from whose hand had sprung everything I could see. He had carved the door, made the stained-glass windows and every other object in sight. Pacem in Terris, I realized, was one man’s act of artistic faith: a work of art outside the parameters of the art world, and also a religious statement unconfined by any religion.
The song of a river ordinarily means the tune that waters play on rock, root, and rapid....This song of the waters is audible to every ear, but there is other music in these hills, by no means audible to all. To hear even a few notes of it you must first live here for a long time, and you must know the speech of hills and rivers. Then on a still night, when the campfire is low and the Pleiades have climbed over the rimrocks, sit quietly and listen for a wolf to howl, and think of everything you have seen and tried to understand. Then you may hear it--a vast pulsing harmony--its score inscribed on a thousand hills, its notes the lives and deaths of plants and animals, its rhythms spanning the seconds and the centuries.
