I was a physically in, mentally out elder. First thing I did was resign as an elder. If I was going to fade for family's sake, I had to get rid of that hindrance. Well, they did that for you.

As for the rest of your "spiritual journey," I believe that each person must find their own way. See where your reading selection and movies and videos take you.
