**An expanded edition of Don Riso's revoluntionary interpretation of the
Enneagram--the ancient psychological system used to understand the human
personality.
**This expanded edition of Don Riso's classic for the first time
uncovers the Core Dynamics, or Levels of Development, within each type.
This skeletal system provides far more information about the inner
tension and movements of the nine personalities than has previously been
published. This increased specificity will allow therapists, social
workers, personnel managers, students of the Enneagram, and general
readers alike to use it with much greater precision as they unlock the
secrets of self-understanding, and thus self-transformation.
