Duality refers to the two internal realities. One reality is our imagination and one reality is what we believe. What is perceived to exist in the external world is a reflection of the words that our minds have been programmed to project and therefore create. Our beliefs sustain the authorised version of reality. The external world is seen or experienced from the perspective of the body through sensory perception. What is perceived as reality is defined with the words we use to define that reality. Our minds are collectively creating reality.
