Mihaly Csikszentmihalyi is the psychologist who summarizes his life’s work in The Flow. The book has been recommended to me several times, from several different sources.
I’ve only read 10% of the book and I can tell you that I don’t believe what Mihaly Csikszentmihalyi believes.
First, he vehemently says that the spiritual does not exist. He gives no proof, no argument. His word is the end of that discussion.
Then he does the same thing for creation. He states quite clearly that the universe was not made for humanity (which I agree with) and so it is hostile to it (possibly) because it is the result of random change (no).
At the 10% mark, he says the same thing about any non-physical experiences. He says there is no such thing as extra-sensory perception and other generalized things that I understand to mean non-physical. So, looking at that I see him saying several things I disagree with. God cannot talk to you. You cannot know when someone you love is in trouble. No one can ever know what another is thinking, without any discussion. These I do not agree with.
