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
The immediate source of a mind... must be a mind which existed before the conception took place; the mind must have a continuity from a previous mind. This we hold to prove the existence of a past life.
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.'

A buddha is someone who finds freedom in good fortune and bad. Such is his power that karma can't hold him. No matter what kind of karma, a buddha transforms it. Heaven and hell are nothing to him. But the awareness of a mortal is dim compared to that of a buddha, who penetrates everything, inside and out.
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.
From a Buddhist point of view, the actual experience of death is very important. Although how or where we will be reborn is generally dependent on karmic forces, our state of mind at the time of death can influence the quality of our next rebirth. So at the moment of death, in spite of the great variety of karmas we have accumulated, if we make a special effort to generate a virtuous state of mind, we may strengthen and activate a virtuous karma, and so bring about a happy rebirth.
