There is something that must be understood in order to achieve clarity: In all personal reality, there is illusion. Then, how can I call it reality? Personal reality is how we construct our personal perception of the world around us. Physical reality is a stable expression of the material universe, one that follows universal laws that are the same in all circumstances, as far as we know at this point in time. Personal reality is fluid, and can alter in any moment, depending on these four things: Physical sense, mental awareness, doubt, and belief. These four things are always affecting our perception of what is happening within and around us. They are the factors that shift our perception constantly between clarity and imagination, and make our lives truly individual, unique experiences.
