NLP
NLP stands for Neuro Linguistic Programming. It encompasses neurology, language, and programming. Neurology refers to how our body functions and reacts to different thoughts. Language is how we communicate with our world, which includes ourselves and others. Programming refers to our behavior, which is in response to our experiences.The theory is that reality is each person's perception of the world. Each of us experience a different reality, which is based our our beliefs. Our beliefs are a map (perception) to how the world around us is put together. For example, if a person believes that all dolls are evil, that person will always be nervous or cautious if they see a doll. Their heart rate may rise in response to fear of the doll, and muscles may be tense ready for fight-or-flight. They make think that doll is out to get them, and anything that they perceive as happening bad to them while around that doll is caused by that doll. Whereas, a person who has no beliefs about dolls may barely even notice the doll being there. You can see how the person who believes dolls are evil could be at the least limited in their ability to function through life if they have to worry about avoiding places there might be a doll and what to do if they see a doll.
The above is an extreme example. But you can see that our beliefs are what affects our behavior. And our beliefs simply come from our experiences and how we have "labeled" them, hence where language comes in. The terms good and bad alone are only our perception, or belief about something. What is good to one person may be bad to someone else. So, we can see that the "thing" itself isn't good or bad, rather it's a person's "belief" or "perception" that labels the "thing" as good or bad. If we can change our language, thus change our beliefs, then we can change our behaviors. The person in the above extreme example who believes dolls are evil, if they can change their language to, "Dolls have no effect on me, they are neither good nor evil" will likely gradually believe that the doll really doesn't have any affect on them and they will change their behavior because they will no longer have to avoid places or have stress added onto their body's. Because of this, they will find life easier, and they may even have health benefits because they will no longer have the stress put on their body.
