Golden Rule

己所不欲，勿施于人 Never impose on others what you would not choose for yourself. - Confucius

Putting oneself in the place of another, one should not kill nor cause another to kill.
One who, while himself seeking happiness, oppresses with violence other beings who also desire happiness, will not attain happiness hereafter. - Buddism

And if thine eyes be turned towards justice, choose thou for thy neighbour that which thou choosest for thyself. - Baha'u'llah

Do to no one what you yourself dislike. - Tobit 4:15

One should never do that to another which one regards as injurious to one’s own self. This, in brief, is the rule of dharma. Other behavior is due to selfish desires. - Brihaspati, Mahabharata

Hurt no one so that no one may hurt you. - Muhammad, The Farewell Sermon

Nothing which breathes, which exists, which lives, or which has essence or potential of life, should be destroyed or ruled over, or subjugated, or harmed, or denied of its essence or potential. In support of this Truth, I ask you a question - "Is sorrow or pain desirable to you ?" If you say "yes it is", it would be a lie. If you say, "No, It is not" you will be expressing the truth. Just as sorrow or pain is not desirable to you, so it is to all which breathe, exist, live or have any essence of life. To you and all, it is undesirable, and painful, and repugnant. - Acaranga Sutra

You shall not take vengeance or bear a grudge against your kinsfolk. Love your neighbor as yourself: I am the LORD. - Leviticus 19:18

The truly enlightened ones are those who neither incite fear in others nor fear anyone themselves. - p.1427, Slok, Guru Granth Sahib (tr. Patwant Singh)
