Book excerpt: Look around you. Notice your surroundings. What you see seems solid and real, a fixed objective reality existing "out there" separate from you. But it's not, Ralph Strauch argues in this provocative exploration of perception, reality, and the mechanisms that link them. What you perceive are images you create, part of a grand illusion that you participate in and support. The external world is a "rich reality" -- offering far wider possibilities than most of us realize. THE REALITY ILLUSION explores the mechanisms you use to to bring the particular world you experience into focus, and explores the benefits of more fully understanding the collective illusion we call reality.
