No one may forsake his neighbor when he is in trouble. Everyone is under obligation to help and support his neighbor as he would himself like to be helped.

Fear guides more to their duty than gratitude; for one man who is virtuous from the love of virtue, from the obligation he thinks he lies under to the Giver of all, there are ten thousand who are good only from their apprehension of punishment.

Your only obligation in any lifetime is to be true to yourself. Being true to anyone else or anything else is not only impossible, but that mark of a fake messiah.
