This sounds like PTSD could be eliminated with enough research into this technique. Deep trauma ghost memories can still trigger fear responses decades later. Why do we have a recurring war cycle every 80 years. People live in fear, hammered into them by their parents and grandparents, but have inadequate response. They kneejerk their way from one fear to another and end up repeating nearly the same situation as last time. History, it is said, rhymes. In the West, everyone looks at those with an opposite opinion, calls them fascist or hitler, believes all measures, no matter their actual morality are justified to eliminate them.It seems we must perceive ourselves from the outside, from a higher perspective, to avoid this perpetual destructive cycle. Maybe, as the Hindus say, only a few enlightened ones escape this karmic wheel each generation. God does not mean it to be otherwise. A golden age would, as the explanation went in the film Matrix, lead to mass suicides, due to lack of stress and struggle, through which we discover meaning.
