Famous quotes containing the word light:
“Her mane falls wild on her forehead,
And the light breeze moves me to caress her long ear
That is delicate as the skin over a girl’s wrist.
Suddenly I realize
That if I stepped out of my body I would break
Into blossom.”
—James Wright (1927–1980)
“So doth, so is Religion; and this blind-
ness too much light breeds; but unmoved thou
Of force must one, and forc’d but one allow;
And the right; ask thy father which is she,
let him ask his; though truth and falsehood be
Near twins, yet truth a little elder is;”
—John Donne (1572–1631)
“The eastern light our spires touch at morning,
The light that slants upon our western doors at evening,
The twilight over stagnant pools at batflight,
Moon light and star light, owl and moth light,
Glow-worm glowlight on a grassblade.
O Light Invisible, we worship Thee!”
—T.S. (Thomas Stearns)
