Spirituality is often seen as a part of religion, it is about rules for dealing with the spirits from the point of view of God the almighty, the creator of our universe. Of course, these rules have been written down by humans which are accepted to be so-called inspired and speaking the words of that same God. Whereas the point of view these rules are taking has to do with eternal good and bad, the morality and dangers of dealing with spirits and engaging with deamons; the point of view expressed in this book is a scientic one. It tries to descipher rules spirits have to obey and it lays down the foundations for behavioral psychology, devoid of good and evil, from the point of view of physical charges. I wish to advocate the point of view that nobody is good or evil, we can all do things which many people accept to be good or evil, but there is no such thing as intrinsically good or bad people. There are on the other hand, strong and weak ones, those with grand visions and small ones, quick and slow thinkers and so on.
