Who has never said "what a stress!" ??
Our life is a three-way relationship : our Ego (what we believe to be) our Higher Self (our divine essence) and Stress !
Since it is not possible to live in a world without stress, our reaction must reduce the damage.
The reptilian brain, the oldest part, which responds to the primordial attack-flight instincts, offers an effective and ancient answer: to move away from the source of stress or fight it.
The other parts of the brain, then, suggest alternative behaviors to the "physical struggle" that favor the elimination of stress guaranteeing the conservation of the species .
But how is our brain composed? Historically it has been considered in many different ways: the ancient Egyptians considered the brain of little importance; in the Greek world, Hippocrates and other philosophers like Plato, identified in the brain the seat of thought; Aristotle, on the other hand, believed that the heart was the seat of intelligence, and saw the brain only as a mechanism for cooling the blood, warmed by the body; Descartes theorizes a division between mind and body, hypothesizing mind-brain dualism.
During the seventies, instead, the neurologist and neuro-scientist Paul Donald MacLean, instead elaborates an evolutionary theory: a trinitarian structure ("Triune Brain").
This interpretation, which exerted a great fascination among intellectuals, is that the brain has developed through a process of successive stratifications in which the layers that form it rest on the previous ones without radical structural changes taking place:
> Reptilian brain (trunk of the encephalon), more internal, is the seat of primary instincts, of autonomous bodily functions;
> brain Mammal (limbic system), represents a progress in the evolution of the nervous system because it is able to develop emotions and adaptive strategies to face the environment;
> consciousness (neocortex), more external, center of conscious thought and language, elaborates strategies and new behaviors that allow to face new and unexpected situations, is associated to self-awareness, to the conception of space and time, to the concept of causality, of constancy and synchronicity.
The three parts of our brain can coexist in equilibrium but often it happens that there is a part that takes over the others and, due to our past experiences, the three brains are therefore not in equilibrium.
In fact, a real "coup" can happen, from one of the three that tends to suffocate the others, while at a later time the opposite can occur. Everything depends on our lifestyle and the environment in which we are born, grow and find ourselves living.
It is in fact thanks to the discovery of the frontal lobe, the ability to acquire new behaviors and new experiences (consciousness), that much of the work should be directed, on the awareness and consequent harmonization of the unexpressed or hypertrophic parts.
The conscience has the difficult role of mother and father of the organism and that of taking responsibility, of protecting and giving direction.
If the conscience is narcissistic, the heart and organism are forgotten and the ego prevails .
