As a registered psychotherapist/healer I have observed many different types of behavior as well observing my own self. When first introduced to the topic of the Enneagram and later studying it I was completely amazed at how complete this system is, more so than other personality profiling. The Enneagram helped me tremendously and so my desire is to allow everyone the same freedom of belief...belief in yourself and that you are an amazing human being.
Alchemy of the Archetype Self 2 goes deeper into reflection of personality types based on the Enneagram compared to the first of that title. It also includes astrology characteristics to compare within the self and relationships.
