They have an ability to see things from a different angle. They are able to provide a humane solution to increase the conscious awareness of others.
What is " higher conscious awareness"? How do you know they had it? How do you know they were not simply imagining things> Mentally ill but plausible?
Jesus Nanak, Buddha, Mohammad, and many more have higher conscious awareness.
Can you tell us more about how we test for " higher conscious awareness"?
Or is this more of "My words mean what I want them to mean. I don;t know what it means but neither do you."?
What is this "different angle"? How do we know this view is true? Do they have another part of the brain to do this or do they have a different brain to ordinary people?
Look, jesuis, what you do not seem to understand is that humans can train their brain to be effeicent at various tasks: they also can train their brain to be irrational, to see visions, etc.
Have you ever considered, say, a great artist? Why can he paint pictures better than you? Probably because he has practised for years and his neurons are trained so that he can control the brush, identify the shades and colours, imagine great scenes.
So it is with these people you mention. The start by thinking something that is not proven. Then they start to get obsessed by it, then they spend years imagining that they have found the "final answer!" They train their brain, but they do not train it correctly. Nothing any of those you mentioned can be tested, or if it can, it is blindingly obvious.
Mystic idiots have been entertaining people since the dawn of mankind - telling stories that they are convinced are correct. If you really want some answer, go and study evolution and evolutionary advantage, have a look at psychology and psychiatry, read some history - they all explain a lot and you don't have to believe in an invisible sky-pixie who poofs things into existence and orders nations destroyed.
