If I understand the inner signals of fear, whose purpose is to educate and inform me, I can choose to make the necessary adjustments in belief and behavior that will prevent for me the unhealthy and painful mental state of being consumed by that fear.
Most often, that state seems one of attempting to avoid the fear, rather than meeting it and receiving what it has to reveal.
In the physical world, a fear signal is often a potentially life-saving reaction that prompts me to move quickly out the way of harm to my physical self. In spiritual terms, I can also experience triggers of fear that point to what could pose danger to my own true and most enduring reality. This signal often arises when I cross the line of moderation and form an attachment to some aspect of the material world.
For every worldly attachment I make, I can gain an unhealthy fear, then easily become overwhelmed by such fears. The remedy, detachment, is in refraining from allowing my physical possessions, the things I do, the things I think, feel, believe, to possess me. For these are what perish.
