The enneagram is an ancient symbol, purported to have originated 3000 years ago by the Sarmung Brotherhood in the Ural mountains.
It is derived form the division of seven into one, yielding a fractional sequence .142857 that is depicted in the inner lines.
The Enneagram is composed of a circle, triangle and the inner line figure.
The circle represents the ostensible series of activities that bring a given project to completion. The triangle represents the principles of the endeavor and the inner lines the strategy.
In a nutshell, the enneagram is a container for infinity. It can contain and give insight regarding any complete process or system and if that said system is not complete, the enneagram will show how to make it complete.
