Famous quotes containing the word folding:
“There’s only one way for an individual to remain upright, not to fall to pieces, not to sink into the mire of self-oblivion ... or self-contempt. That’s calmly to turn away from everything, to say, “Enough!” and, folding one’s useless arms across one’s empty breast, to retain the ultimate, the sole attainable virtue, the virtue of recognizing one’s own insignificance.”
—Ivan Sergeevich Turgenev (1818–1883)
“I’m folding up my little dreams
Within my heart tonight,
And praying I may soon forget
The torture of their sight.”
—Georgia Douglas Johnson (1886–1966)
“A little sleep, a little slumber, a little folding of the hands to rest, and poverty will come upon you like a robber, and want, like an armed warrior.”
—Bible: Hebrew, Proverbs 6:10.
