The Golden Rule

Never impose on others what you would not choose for yourself.
(Confucius in China)
That which you hate to be done to you, do not do to another.
(Ancient Egypt)
What you do not want to happen to you, do not do it yourself either.
(Ancient Greece)
Hurt not others in ways that you yourself would find hurtful.
One should never do that to another which one regards as injurious to one’s own self. (Hinduism)
Do unto others as you would have them do unto you.
