The Golden Rule... "Do unto others as you would want them to do unto you." Now let's look at what other religions have to say about that:
Bahá'í: "And if thine eyes be turned towards justice, choose thou for thy neighbour that which thou choosest for thyself."
Buddhism: "Hurt not others in ways that you yourself would find hurtful."
Confucianism: "Do not do to others what you do not want them to do to you."
Egyptian: "Do for one who may do for you, that you may cause him thus to do."
Hinduism: "Do naught unto others which would cause you pain if done to you."
Humanism: "Don't do things you wouldn't want to have done to you."
Jainism: "A man should wander about treating all creatures as he himself would be treated."
Judaism: "What is hateful to you, do not to your fellow man. This is the law: all the rest is commentary."
Native American Spirituality: "Do not wrong or hate your neighbor. For it is not he who you wrong, but yourself."
Shinto: "The heart of the person before you is a mirror. See there your own form."
Sikhism: "No one is my enemy, none a stranger and everyone is my friend."
Taoism: "Regard your neighbor's gain as your own gain, and your neighbor's loss as your own loss."
Yoruba in Nigeria: "One going to take a pointed stick to pinch a baby bird should first try it on himself to feel how it hurts."
Zoroastrianism: "Whatever is disagreeable to yourself do not do unto others."
