Being awakened or enlightened does not mean you no longer feel fear.  Fear has a physical component to it.  This is built into the human experience.  It is hard-wired into your body.  Fight or flight will kick in and you will feel the inevitable surge of adrenaline when there is the perception of danger.  The physical body does not discern the afterlife.  It does not know that there is a blended yet separate and eternal aspect within.  When you become aware of adrenaline or a sudden fright, you the soul can train yourself to use discernment.  Yes, of course, you will take appropriate action, as necessary, but fear need no longer dominate your life when you realize that beyond the initial instinctual reaction, the soul can always make the higher choice of peace.  You are so very loved.
