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
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.

Dangerous consequences will follow when politicians and rulers forget moral principles. Whether we believe in God or karma, ethics is the foundation of every religion.
The present moment, though, is outside of time, it’s Eternity. In India they use the word “karma” for lack of any better term. But it’s a concept that’s rarely given a proper explanation.
