What Is a Power Greater than You?

Fear can become a power greater than myself. ~ Family Groups, Al-Anon. Courage to Change—One Day at a Time in Al‑Anon II (Kindle Locations 3916-3917). 

An old alcoholic known far and wide as "Barefoot"
called his Higher Power "Charlie, My Very Best Friend"
and once said, "I have found well over 10,000 positive names
that people around the world have used to address their Higher Power."
A name I have used is "Demiurge" defined as "a being
responsible for the creation of the universe" and associated
with Plato and gnosticism. I have heard GUS (Guy UpStairs)
and Harold (Harold be thy name.)
Step Two says we came to believe a Power greater than ourselves
could restore us to sanity, and we are free to set the job description
for our own Higher Power. 
There are no don'ts in the step but we should consider the should nots.
Food doesn't work... we've tried that. Substituting another
dangerous habit is not advisable. Fear may well be a power
that fits the description, but no better choice than sugar, drugs,
alcohol or other people. Choose and name your own Higher Power
but be sure this Power is one to whom you can surrender control.
