Besides that I want to focus on the Guru or Shaman. Human have a strong need for a shaman or Guru. All human groups throughout history have shown this need for some meta magical personality. This goes for groups of the most primitive, vicious type and upward. And their beliefs about their Shaman are if you look into it are about the same as what any modern cult group thinks about their leader. It is basic human trait and need to have a Shaman. These shamans are not schizophrenic but schizo-typal. They control themselves so the visions and hallucinations occur at the right time and place.
Meta magical thinking is the major characteristic of these schizoid gurus and shamans. They believe in strange things. They are really into fantasies in a "frenzy" kind of way. Maybe it is New Age or whatever. What ever religious structure they have it is very literal and concrete. They tend towards extremely literal explanations of religious events or writings.
When you see this you should know you are dealing with a person that has a mild version of schizophrenia. He or she is Schizotypal.
Nowadays in secular society such people get jobs that fit this kind of personality. But in more religious societies these people tend to go to the top of the hierarchy.
