My sponsor was pretty free with me on that...I listened to speaker tapes...Looked at websites...Other Books...Other opinions from other AA members...I wanted to know as much as I could about what I was doing...The 12 steps....I got through them and had that psychic change....Spirtual Awakening...As a result of those steps. I haven't sponsored anybody yet...I pray for the opportunity...When God's ready for me to do it...I'll do it. But I don't see any reason to limit what someone wants to learn or when they want to do it....It's their journey with their Higher Power...Not mine.
