Here are some resources for you… I’ll continue to update them. Those in the first section will be ones I personally have read. Below there’s a list of contributions of our friends in my Facebook Enneagram group.
The Road Back to You by Ian Morgan Cron & Suzanne Stabile. – A very accessible introduction
The Wisdom of the Enneagram by Don Richard Riso & Russ Hudson—This one of the classic go-to sources. It has a quick test that can actually be a first step toward knowing your number. *Remember the tests aren’t always definitive.
The Sacred Enneagram by Christopher Heuertz—The strength of this book is in the easy to read sidebars of things for each type like the primary needs, the childhood wounds, the virtues, the vices, names of the types and more helpful, easy to scan details. It also breaks down the diagram into smaller bits to understand it better.
The Complete Enneagram: 27 Paths to Greater Self-Knowledge—This one does a great job of the deeper layers of subtypes
Using the Enneagram in Prayer by Suzanne Zuercher—This one customizes contemplative prayer practices by type.
