Confucius remarked: "While his parents are
living, a son should not go far abroad. If
he does, he should let parents know where
he goes."

Student TzuGong ask: "Is there one word
which may guide one in practice throughout
his whole life?"
Confucius answered: "The word 'charity' is
perhaps the word. What you do not wish
others do to you, do not do unto them."
