Events in this framework form dreaming of Great Cosmic Mind. Life experience of each individual being - large and small - forms individual sub-dream. Parts of theses dreams are happy, some of them are nightmares, most are somewhere between both extremes.
Any individual activity can be judged from this point of view. If cumulative effect tips scales of overall quality of Great Cosmic Mind's dream in direction of happy dream, it is good. If it tips scales of overall quality of Great Cosmic Mind's dream in direction of nightmare it is evil.
The life is seldom black and white and compromises have to be made all the time but this rule gives clear indication in most situations.
