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.
We manage to swallow flesh only because we do not think of the cruel and sinful thing that we do. There are many crimes which are the creation of man himself, the wrongfulness of which is put down to their divergence from habit, custom, or tradition. But cruelty is not of these. It is a fundamental sin, and admits of no argument or nice distinctions. If only we do not allow our heart to grow callous, its protest against cruelty is always clearly heard; and yet we go on perpetrating cruelties easily, merrily, all of us - in fact, anyone who does not join in is dubbed a crank.
The way of presentation is different according to each religion. In theistic religions like Buddhism, Buddhist values are incorporated. In nontheistic religions, like some types of ancient Indian thought, the law of karma applies. If you do something good, you get a good result. Now, what we need is a way to educate nonbelievers. These nonbelievers may be critical of all religions, but they should be decent at heart.
The universe that we inhabit and our shared perception of it are the results of a common karma. Likewise, the places that we will experience in future rebirths will be the outcome of the karma that we share with the other beings living there. The actions of each of us, human or nonhuman, have contributed to the world in which we live. We all have a common responsibility for our world and are connected with everything in it.
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.
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.
