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.
Delusions are states of mind which, when they arise within our mental continuum, leave us disturbed, confused and unhappy. Therefore, those states of mind which delude or afflict us are called 'delusions.'
From the scientific view, the theory of karma may be a metaphysical assumption -- but it is no more so than the assumption that all of life is material and originated out of pure chance
O youth or young man, who fancy that you are neglected by the gods, know that if you become worse, you shall go to worse souls, or if better to the better... In every succession of life and death, you will do and suffer what like may fitly suffer at the hands of like. This is the justice of heaven.
We are the makers of our own lives. There is no such thing as fate. Our lives are the result of our previous actions, our karma, and it naturally flows that, having been ourselves the makers of our karma, we must also be able to unmake it.
Dependent Origination is the teaching (that life) is not the mere play of blind chance, but has an existence that is dependent upon conditions. That, precisely with the removal of these conditions, those things that have arisen in dependence upon them-thus also all suffering-must perforce disappear and cease to be.
To find Buddha, you have to see your nature. Whoever sees his nature is a Buddha. If you don't see your nature, invoking buddhas, reciting sutras, making offerings, and keeping precepts are all useless. Invoking buddhas results in good karma, reciting sutras results in a good memory, keeping precepts results in good rebirth, and making offerings results in future blessings-but no Buddha.
