When there is a symptom or communication, it is important to pay attention. The meaning of your communication is the response you get. Communication creates an experience in the listener or reader. The result is the response we elicit. That response may not necessarily match what we intended to communicate.
Communication is redundant.
We are always sending messages in all three major sensory modalities. NLP checks for congruence in these messages. Choice is better than no choice. The element in a system with the most flexibility has the most control. People always make the best choice available to them at the time.
