“Humans are born with a hodge-podge of various brain circuits, that possess the seeds of peace, fear, love, hate, rage, pain, love, stress and faith. All these elements compose the emotional domain of our mental life. All these characters are ingrained in our limbic system, that keep our head straight in the path of survival. We humans can survive, only if, all these elements of our brain circuits function properly. Failure of any one element would mean extinction of the whole species.”
