The Structure: Wings, Arrows & Centers

The Enneagram is more than just nine static categories. The diagram contains interconnections that show how types relate to one another dynamically — especially under stress and growth.

• Wings: The two numbers sitting beside your type on the circle. Your 'wing' is the adjacent type that most influences your personality (e.g., a Type 4 may have a 3-wing or a 5-wing, written as 4w3 or 4w5).

• Integration (Growth) Lines: The internal arrow lines show where a type moves toward in health and growth — e.g., Type 1 integrates toward Type 7 behavior when thriving.

• Disintegration (Stress) Lines: Under stress, a type moves toward another type's unhealthy patterns — e.g., Type 1 disintegrates toward Type 4 behaviors under pressure.

• The Three Centers: The nine types are grouped into three 'centers of intelligence' — Heart (Feeling), Head (Thinking), and Body (Instinct) — each containing three types.

• Levels of Development: Each type has nine levels ranging from healthy to average to unhealthy, describing how the same type looks across a spectrum of psychological health.
