Fear Not The Fear but Fear Doing Wrong.

"Fear is the main source of superstition, and one of the main sources of cruelty. To conquer fear is the beginning of wisdom." ~ Bertrand Russell 

Irrational fear perhaps, however the healthy fear is a sense of the reptilian part of the brain responsible for survival and attack or flee reactions in life-threatening situations, which builds up memory and pattern recognition to avoid similar circumstances that are running at all times in the background of the subconsciousness, which is measuring six to seven billion operations per any given moment then filtering it all down to two to three thousand awareness "memos" presented to the conscious self -- the Christ -- being aware, which comes through, metaphorically speaking, St. Peter's gates of perception, aka the pineal gland, with twelve apostles representing twelve energetic centres, chakras, of human body, the conscious "Christ" awareness being the centre -- the thirteen, twelve spheres around the central one projecting fractal mirror reflection of itself in different scales of harmonic resonances, hence the need to maintain basic stability and functions of critical systems which then manifest in real life in various forms of fears and fearlessness and plethora of other emotions, some pleasant and some are not, however just because it is pleasant does not mean it is not harmful or beneficent and vise versa. 

At any moment the brain scans the environment via all its sensory to check if it is safe or not, it monitors the health of the body and its all integral functionality, it checks against the memory banks if the situation is good or bad, how good or bad compared to other events in memory, is it about to loose consciousness because it is drunk too much alcohol or other reason, did it lose anything, it keeps track of everything important, the intelligence then makes an educated projection how things will unravel utilizing what strategy, would it be instinctual response of the body if things are happening very fast, or if there is time to think it through the intelligence can contribute significantly, so next time one drinks close to the same amount of alcohol the last time that was too much the brain will recognize it, hopefully, or else, if there is not enough information, rely on intuition, but the intent is always clear, to the soul and the rest of the universe, which ultimately determines the overall outcome, which is the Golden Rule -- as it comes so it goes -- of all spiritual teaching across all times and religions, hence in stressful situations the feeling of fear would block higher reasoning preparing the body to deal with the emergency situation, then of course if there is no need for it and all is well the higher reasoning is much more accessible hence what makes us human part of the brain blossoms into creative joyful activity. 

Then of course the so-called neuropeptides, smallest bits of information produced in the human body, fill the bloodstream with either positive or negative neuropeptides that in turn delivered to the brain where they are consumed by the positive or negative neural receptors. Now, each moment there are mass deaths and births of old and new brain cells and what kind the new ones are going to be is determined by predominant "food" supply of the either positive or negative neuropeptides. Thus, if the body is stressed and its blood is filled with negatively charged neuropeptides then the new brain cells will form to absorb negative neuropeptides while ignoring positive ones, and vise versa, if there is not bad stress then the body is filled with positive energy and it is actually depends on the positive, or negative, reinforcement because it is "addicted" to either positive or negative "food" supply of either bad stress or the complete lack of it. That's why the old wisdom points to the inner self and change from within. It takes to change one's heart and change one's world.
