Our Amygdala is the guardian of the Self, our subconscious, our Who We Are, our Soul, our Psyche. Our Ego, our conscious state, our Who We Think We Are, our "I think therefore I am" engine of our persona  often sends conflicting messages to the Amygdala. Psychology and specifically Psychometrics and the Open Loop Limbic System, is the study of the Ego. Astro-Psychology identifies the nature of both Self and Ego along with their reason for being together.
