Personality Types: Using the Enneagram for Self-Discovery
Written by Don Richard Riso with Russ Hudson

Unequaled in the Enneagram field, the authors provide precise and comprehensive systematic descriptions of each personality type, as well as new, expanded descriptions of each type's two major subtypes and its Directions of Integration and Disintegration. Augmented by more than 150 pages, this entirely revised edition reveals new insights that have never been published before, including the authors' revolutionary discovery, the Core Dynamics, which give the specific motivations, attitudes, fears, and desires at each of the nine internal Levels of Development for each type, as well as the parental influences on each type, an expanded history of the Enneagram, new material on the Instinctual Variants, and much, much more.
