Explanation:
What follows is a meditation I put together for an Overeaters Anonymous retreat.  I used only material from AA’s “Big Book” and “Twelve and Twelve,” then combined that with what I had learned about deep breathing exercises and meditation.  At that retreat, I read the following slowly, allowing time for reflection and breathing in between each line.  You are welcome to make a recording of your own voice reciting these lines from the AA material, or make up your own to help you in your meditation exercises.
.
Invitation:
(We of agnostic temperament) We found that as soon as we were able to lay aside prejudice and express even a willingness to believe in a power greater than ourselves, we commenced to get results, even though it was impossible for any of us to fully define or comprehend that Power, which is God.   AA, p.46
.
Introduction to breathing meditation (Not from program material):
Be seated comfortably with arms in a comfortable position, perhaps with hands open in front of you as if receiving a gift.  Breathe slowly and deeply from the diaphragm, in through the nose, and out the mouth, holding each breath for about a count of four as each breath takes about the same count of four to draw and exhale.  Close your eyes and imagine a peaceful scene of your choosing where all is calm and comfortable.  Quiet your mind as much as it is possible, but do not do yourself harm by self-criticizing if thoughts occur to you.  Simply steer them away and dismiss them from you mind, pushing them out with the next breath you exhale.  
.
The “keynotes to harmony” in the 12&12 are “courtesy, kindness, justice and love.” (p.93)  Focus on these as you deeply breathe in the cleansing breath of your Higher Power.

(Step Three) God, I offer myself to Thee – to build with me and to do with me as Thou wilt.  Relieve me of the bondage of self, that I may better do Thy will.  Take away my difficulties, that victory over them may bear witness to those I would help of Thy Power, Thy Love, and Thy Way of life.  May I do Thy will Always!   AA, p.63

We begin to feel the nearness of our Creator.  (We feel we are on the Broad Highway, walking hand in hand with the Spirit of the Universe.)  We thank God from the bottom of our heart that we know Him better.   AA, p.75

We asked God to help us show (those who wronged us) the same tolerance, pity, and patience that we would cheerfully grant a sick friend.   …God save me from being angry.  Thy will be done.    AA, p.67

Lord, make me a channel of thy peace –
that where there is hatred, I may bring love –
that where there is wrong, I may bring the spirit of forgiveness –
that where there is discord, I may bring harmony –
that where there is error, I may bring truth –
that where there is doubt, I may bring faith –
that where there is despair, I may bring hope –
that where there are shadows, I may bring light –
that where there is sadness, I may bring joy.  
Lord, grant that I may seek rather to comfort than to be comforted –
to understand, than to be understood –
to love, than to be loved.  
For it is by self-forgetting that one finds.  It is by forgiving that one is forgiven.  It is by dying that one awakens to Eternal Life.  Amen.  12&12, p.99

We ask simply that throughout the day God place in us the best understanding of His will that we can have for that day, and that we be given the grace by which we may carry it out.  12&12, p.102
 

(Step Seven) My Creator, I am now willing that you should have all of me, good and bad.  
I pray that you now remove from me every single defect of character which stands in the way of my usefulness to you and my fellows.  
Grant me strength as I go out from here, to do your bidding.  Amen.  AA, p.76

God grant me the serenity to accept the things I cannot change,
courage to change the things I can,
and wisdom to know the difference.  
Thy will, not mine, be done.  12&12, p.41
