"Gold is for the mistress -- silver for the maid --
Copper for the craftsman cunning at his trade."
said the Baron sitting in his hall,
"But Iron -- Cold Iron -- is master of them all."
Rudyard Kipling, Rewards and Fairies
He who walks in the company of fools suffers a long way; company with fools, like an enemy, is always painful; company with the wise is pleasure, like meeting with kinsfolk. Therefore, one ought to follow the wise, the intelligent, the learned, the much enduring, the dutiful, the elect; one ought to follow a good and wise man as the moon follows the path of the stars.
--Buddha, The Dhammapada, Chapter XV, Verses 207-208.
