|All things whatsoever ye would that men should do to you, do ye so to them; for this is the law and the prophets.
|Do not do to others what you would not like yourself. Then there will be no resentment against you, either in the family or in the state.
|Hurt not others in ways that you yourself would find hurtful.
|This is the sum of duty; do naught onto others what you would not have them do unto you.
|No one of you is a believer until he desires for his brother that which he desires for himself.
|What is hateful to you, do not do to your fellowman. This is the entire Law; all the rest is commentary.
Talmud, Shabbat 3id
|Regard your neighbor’s gain as your gain, and your neighbor’s loss as your own loss.
Tai Shang Kan Yin P’ien
|That nature alone is good which refrains from doing another whatsoever is not good for itself.
