Hi Angulimala!
What a great post!
I'm a big fan of Bill Alexander's books - Cool Water particularly. He too is a Buddhist who got sober in AA. I identify a lot with him and his outlook.
My own experience is that my life of sobriety within AA has a great big set of imperfections. But I would not, under any circumstances, swap those imperfections for the imperfections my life had when I was a practicing drunk outside the fellowship! My challenge therefore, is to live with the imperfections of the fellowship and find peace. It's easier than the alternative!
