I have this tattooed on my left side! I love the saying and it's a perfect description of Karma, don't judge/discriminate and don't do to someone what you wouldn't want done to you.
There is nothing so delightful as the hearing or the speaking of truth. For this reason, there is no conversation so agreeable as that of a man of integrity, who hears without any intention to betray, and speaks without any intention to decieve.
