Let not your heart be offended

"Let not your heart be offended with anyone. If someone commits an error and wrong toward you, you must instantly forgive him. Do not complain of others. Refrain from reprimanding them, and if you wish to give admonition or advice, let it be offered in such a way that it will not burden the bearer. Turn all your thoughts toward bringing joy to hearts. Beware! Beware! lest ye offend any heart." Abdu'l-Baha

For one another must ye give up even life itself.

For one another must ye give up even life itself. To every human being must ye be infinitely kind. Call none a stranger; think none to be your foe. Be ye as if all men were your close kin and honoured friends. Walk ye in such wise that this fleeting world will change into a splendour and this dismal heap of dust become a palace of delights. Such is the counsel of 'Abdu'l-Baha, this hapless servant.
