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.
The Buddhist, who thanks no man, who says "Do not flatter your benefactors," but who, in his conviction that every good deed can by no possibility escape its reward, will not deceive the benefactor by pretending that he has done more than he should, is a Transcendentalist.
