Additional Information:
The enneagram of a human being is showing three octaves:

1- The first octave is the digestion of food and its first shock occurs at point 3-4 (mi-fa of the first octave). This is the automatic shock of breathing.
2- The second octave is the digestion of air. This octave begins at point 3, and its first shock is at point 5-6 (mi-fa of the second octave). This is the intentional shock of conscious labor.
3- The third octave is the digestion of impressions. This octave begins at point 6, and its first shock occurs is at points 8-9 (mi-fa of the third octave). This is the intentional shock of voluntary suffering.

Points 3, 6 and 9 supposedly represent the affirming, denying and reconciling forces.
