Keep close to Nature's heart … and break clear away, once in a while, and climb a mountain or spend a week in the woods. Wash your spirit clean. - John Muir

Our flesh-and-bone tabernacle seems transparent as glass to the beauty about us, as if truly an inseparable part of it, thrilling with the air and trees, streams and rocks, in the waves of the sun, — part of all nature, neither old nor young, sick nor well, but immortal.

I drifted on through the midst of this passionate music and motion, across many a glen, from ridge to ridge; often halting in the lee of a rock for shelter, or to gaze and listen. Even when the grand anthem had swelled to its highest pitch, I could distinctly hear the varying tones of individual trees [...] and even the infinitely gentle rustle of the withered grasses at my feet. Each was expressing itself in its own way, - singing its own song, and making its own peculiar gestures - manifesting a richness of variety to be found in no other forest I have yet seen.

When we try to pick out anything by itself we find that it is bound fast by a thousand invisible cords that cannot be broken, to everything in the universe.
