Those green-robed senators of mighty woods,
Tall oaks, branch-charmed by the earnest stars,
Dream, and so dream all night without a stir…

~ John Keats, Hyperion, Book I

When the oak is felled the whole forest echoes with it fall, but a hundred acorns are sown in silence by an unnoticed breeze.

~ Thomas Carlyle

The greatest achievement was at first and for a time a dream. The oak sleeps in the acorn, the bird waits in the egg, and in the highest vision of the soul a waking angel stirs. Dreams are the seedlings of realities.

~ James Allen
