Surely if living creatures saw the results of all their evil deeds, they would turn away from them in disgust. But selfhood blinds them, and they cling to their obnoxious desires. They crave pleasure for themselves and they cause pain to others; when death destroys their individuality, they find no peace; their thirst for existence abides and their selfhood reappears in new births. Thus they continue to move in the coil and can find no escape from the hell of their own making.
For, owners of their deeds (karma) are the beings, heirs of their deeds; their deeds are the womb from which they sprang; with their deeds they are bound up; their deeds are their refuge. Whatever deeds they do-good or evil-of such they will be the heirs. And wherever the beings spring into existence, there their deeds will ripen; and wherever their deeds ripen, there they will earn the fruits of those deeds, be it in this life, or be it in the next life, or be it in any other future life.
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.
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.
Still others commit all sorts of evil deeds, claiming karma doesn't exist. They erroneously maintain that since everything is empty, committing evil isn't wrong. Such persons fall into a hell of endless darkness with no hope of release. Those who are wise hold no such conception.
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.
All major religious traditions carry basically the same message, that is love, compassion and forgiveness the important thing is they should be part of our daily lives.
