The Type Codex is the deepest layer of type material on the site — nine pages, one per type. Each page covers a single type at structural depth: the core motivation, the defense pattern, the lost recognition, the virtue, the path of integration, and the way the type appears in different sequence positions. Each runs to roughly seventeen chapters of treatment.
If you’re new to the framework, the public Type Profiles are a better starting point. This reference is for people working seriously with their sequence over time — coaches, practitioners, students of the broader Enneagram tradition, and individuals who want the full structural picture rather than the working summary.
Most readers find it useful to start with their dominant type, then their secondary, then read the others in whatever order feels relevant. The pages are designed for non-linear use; you can return to a single chapter when a question surfaces in your life rather than reading front-to-back.
Once you’ve worked through your top types, the next most useful reading depends on what question is alive for you. If you’re trying to understand a specific person in your life, read their types. If you’re working on a development edge, read the types you suspect are buried — the bottom of your sequence is often the place where deliberate work has the most leverage.
The Three Centers and Hornevian Groups theory pages help you read across the nine — understanding why your dominants share certain features, where your structural blind spots probably are, and what other types your existing structure is closest to.
