Enneagram

This symbol is a visual representation of the ancient Enneagram personality typing system that consists of nine different types. The standard enneagram figure is usually composed of three parts; a circle, an inner triangle and an irregular hexagonal "periodic figure." According to esoteric spiritual traditions, the circle symbolizes unity, the inner triangle symbolizes the "law of three" and the hexagon represents the "law of seven."
