Famous quotes containing the words sound and/or image:
“An old pond—
a frog tumbles in—
the sound of water.”
—Matsuo Basho (1644–1694)
“Man is an exception, whatever else he is. If he is not the image of God, then he is a disease of the dust. If it is not true that a divine being fell, then we can only say that one of the animals went entirely off its head.”
