Good for the body is the work of the body, and good for the soul is the work of the soul, and good for either is the work of the other. – Henry David Thoreau

Leaves are light, and useless, and idle, and wavering, and changeable; they even dance; and yet God in his wisdom has made them a part of oaks. And in so doing he has given us a lesson, not to deny the stout-heartedness within because we see the lightsomeness without. – Augustus William Hare and Julius Charles Hare, Guesses at Truth, by Two Brothers
