Famous quotes containing the words magic and/or number:
“Without, the frost, the blinding snow,
The storm-wind’s moody madness—
Within, the firelight’s ruddy glow,
And childhood’s nest of gladness.
The magic words shall hold thee fast:
Thou shalt not heed the raving blast.”
—Lewis Carroll [Charles Lutwidge Dodgson] (1832–1898)
“If I could live as a tree, as a river, as the moon, as the sun, as a star, as the earth, as a rock, I would. ...Writing permits me to experience life as any number of strange creations.”
—Alice Walker (b. 1944)
