NLP is the study of the impact of languages on the thought processes of our mind. It's considered the controlling mechanism of the brain. Once someone learns to communicate using NLP, his or communication becomes more effective.
Thought processes and our 5 senses in our brain are initiated by stimulus we get from our sense organs. The stimuli from the plethora of sense organs are then communicated via electro chemical signals to our brain. These signals are then translated into images that can be recognized by our brain. The information that isn't processed by the brain in the form of electro chemical signals is called the primary experience. It's initially analyzed or interpreted by the brain. The image conceived from the primary experience is called secondary experience.
NLP can be used to make sense of how we are carrying out things and how they can be done better. Secondary experience is developed from a person's past experiences. The primary experience is the actual truth of a situation. If you can communicate with someone using the primary experience, their way of thinking can be changed. Reprogramming the internal processes taking place in a person is very helpful. This will inevitably lead to a change in behavior in the person, which in turn produces better results.
Often blame is placed on the person, which is an attack on the identity level. When in truth the change needs to occur on the behavior and attitudes level and how that person behaves. What needs to change is a change in the attitudes and behavior of a person, not their personality or who they are. This is a recipe for success when bringing out the desired changes in the life of a person. If you're looking to be a better manager, communicator or even public speaker, using NLP will allow you to communicate more effectively. Also, if change is desired with yourself, or someone else that might need it, NLP is very helpful in bringing about change in a person.
