Being all equal and independent, no one ought to harm another in his life, health, liberty, or possessions.

Choose not to be harmed—and you won't feel harmed. Don't feel harmed—and you haven't been. (Hays translation)

If you truly loved yourself, you could never hurt another.

NOT CAUSING HARM obviously includes not killing or robbing or lying to people. It also includes not being aggressive — not being aggressive with our actions, our speech, or our minds. Learning not to cause harm to ourselves or others is a basic Buddhist teaching on the healing power of nonaggression. Not harming ourselves or others in the beginning, not harming ourselves or others in the middle, and not harming ourselves or others in the end is the basis of enlightened society.

Choose not to be harmed -- and you won't feel harmed. Don't feel harmed -- and you haven't been.

Choose not to be harmed — and you won’t feel harmed. Don’t feel harmed — and you haven’t been.

I was never in this situation to be like, 'Ah, let me hurt people',

Another person will not hurt you without your cooperation; you are hurt the moment you believe yourself to be.

Never do an enemy a small injury.

Choose not to be harmed—and you won’t feel harmed. Don’t feel harmed—and you haven’t been.

Do nothing to others which if done to you would cause you pain. This is the essence of morality.

Do not hurt where holding is enough;
do not wound where hurting is enough;
do not maim where wounding is enough;
and kill not where maiming is enough;
the greatest warrior is he who does not need to kill.

Nobody is hurt. Hurt is in the mind. If you can walk, you can run.

I always had a strong reluctance to hurt people, which is always the best way of hurting oneself.
