A useful metaprogram is the one called “filter on/off”. The brain has to filter out a lot of the data that the five senses produce in order to work. Every person filters a lot. Yet, sometimes some people filter a little bit less than others. Even if an average person filters out like 98% of the data and someone else would filter only 97% that 1% difference can mean a whole lot of problems. For instance, in most cases of real High Sensitive Persons (HSP) what is happening is that said person is filtering maybe 1% or 2% less than average. For instance, if people experience something traumatic the brain might change the way it filters and filter less in order to try to not overlook what happened just before the traumatic event in the senseless notion that if only the brain had filtered less the trauma might have been avoided. Of course this is nonsense and fortunately with NLP it is easy to get the brain to filter more so the HSP disappears.
The fundamental errors. – For man to feel any sort of psychical pleasure or displeasure he must be in the grip of one of these two illusions: either he believes in the identity of certain facts, certain sensations: in which case he experiences psychical pleasure or displeasure through comparing his present states with past ones and declaring them identical or not identical (as happens in all recollection); or he believes in freedom of will, for instance when he thinks ‘I did not have to do this’, ‘this could have happened differently’, and likewise gains pleasure or displeasure. Without the errors which are active in every psychical pleasure and displeasure a humanity would never have come into existence – whose fundamental feeling is and remains that man is the free being in a world of unfreedom, the eternal miracle worker whether he does good or ill, the astonishing exception, the superbeast and almost-god, the meaning of creation which cannot be thought away, the solution of the cosmic riddle, the mighty ruler over nature and the despiser of it, the creature which calls its history world history! – man is the vanity of vanities.
