Someone posted on the AA forum recently about a prayer I only heard about for the first time about a year ago. It's called the "Set-Aside" Prayer, and it can be customized for whatever use you want to make of it:
"Dear God, please set aside everything I think I know (about myself, my disease, the Big Book, the 12 Steps, the Program, the Fellowship, the people in the fellowship, all spiritual terms, and especially about you God) so I may have an open mind and a new experience (with all these things). Please help me see the Truth. Amen."
It's often used when beginning a session of Step work or a BB study or working with someone else (a sponsor or sponsee).
