Because such a vast amount of territory is covered by human nature, it would be useful to have an accurate map of that familiar yet ever-unexplored territory. It would be helpful to have a reliable means of charting who we are and where we are going so that we will not lose our way.

We believe the Enneagram (pronounced "ANY-a-gram") is the map of human nature that people have long sought. Although the Enneagram symbol is ancient, as are many of the roots of its psychological theory, it is remarkably contemporary because human nature has not changed. The Enneagram, which has been transmitted to us from a variety of history's rich spiritual and philosophical traditions, represents a profound understanding of human nature, something needed as much now as it was in the past. The Enneagram presented here is a distillation of teachings from several profound schools of spiritual wisdom, combined with insights from modern psychology. It is at once ancient and modern, representing a marvelous and dynamic synthesis of old and new. The purpose of this book is to introduce the general reader to this remarkable system.
