The Monad is the indivisible single source of reality. In science, it's the Big Bang singularity from which the universe emerged. In mathematics, the Monad is defined as the zero-point origin of all numbers. For theologians, the Monad is the logos or Word of God. In philosophy, it's the basic Substance at the root of both mind and matter.

In your life, the Monad is the singularity in your own consciousness, the point of awareness from which you experience the world. You are conscious because the universe is conscious, and the commonplace experience of being a single point of awareness in your own mind— of living in your own little world—is a reflection of the Monad in you. The focus in this book is on your relationship to the greater Monad. Whatever the ultimate truth of the universe, that is not going to change. What changes is your piece of the puzzle—the singularity of consciousness in your personal space around which you've built your entire life.
