Communication starts with input (an external event) – what I say to you, or the email I send to you, or the angry look you see on my face.  You interpret the event using filters which are made up of your experiences, history, prejudices and more.  The interpretation creates an ‘internal map’ of meaning or a ‘map of your world’ – it is made up of the pictures you see in your mind.  The map is how your brain processes and makes sense of the filtered input.  If it recognizes the input i.e. you have seen me make that face before, you are able to easily map out what is happening.  You would start picturing me yelling at you or sensing how you are about to feel.  That map generates a state of being within your mind.  You might suddenly be in a state of mind such as anger, fear, resistance or any other emotion and associated thoughts.  That state of being will then lead to your behaviour and your response.  Will you scowl back at me?  Ask what’s wrong?  Run away?
