"To trace the history of a river, or a raindrop, as John Muir would have done, is also to trace the history of the soul, the history of the mind descending and arising in the body. In both, we constantly seek and stumble on divinity, which, like the cornice feeding the lake and the spring becoming a waterfall, feeds, spills, falls and feeds itself over and over again."

-Gretel Ehrlich, "River History"
