Attempting the mastery of fear is useless. In fact, it asserts the power of fear by the very assumption that it need be mastered. The true resolution rests entirely on mastery through love. What is not love is always fear and nothing else. Where one appears, the other disappears, and what you share becomes the only one you have.
Fear takes many forms, just as love is expressed in many ways.
To become acquainted with the many faces of fear is an interesting exploration. It might be helpful to pause here and present some basic components of our approach to dealing with difficult emotions like fear, or guilt, or anger. Acceptance - the willingness to let go of judgments about your feelings so that you no longer need to deny, repress or resist them. Allowing - letting the energy and flow of an emotion to move through your experience as you observe it, without trying to change it, stop it, avoid it, etc. We forget it is just an idea we are having.
