Famous quotes containing the word roots:
“The greatest gifts you can give your children are the roots of responsibility and the wings of independence.”
—Denis Waitly. Quoted in The Winning Family, ch. 25, by Louise Hart (1987)
“Our roots are in the dark; the earth is our country. Why did we look up for blessing—instead of around, and down? What hope we have lies there. Not in the sky full of orbiting spy-eyes and weaponry, but in the earth we have looked down upon. Not from above, but from below. Not in the light that blinds, but in the dark that nourishes, where human beings grow human souls.”
—Ursula K. Le Guin (b. 1929)
“Sprung from the West,
He drank the valorous youth of a new world.
The strength of virgin forests braced his mind,
The hush of spacious prairies stilled his soul.
His words were oaks in acorns; and his thoughts
Were roots that firmly gript the granite truth.”
—Edwin Markham (1852–1940)
