“Nor sword nor spear the stripling took, / But chose a pebble from the brook.”
William Cowper

“To forget one's ancestor's is to be a brook without a source, a tree without root”
Chinese Proverbs
“And this our life, exempt from public haunt, finds tongues in trees, books in running brooks, sermons in stones, and good in everything.”
