I also took a while, 2 trips through a recovery program and many many meetings to finally see what was meant by that part of the program. Many many people have managed to work out some sort of "higher power" I have heard of light bulbs having that distinction, but it comes down to whatever works. The actual spiritual feeling that comes over me at a meeting makes it work every time... the group can be the power you are seeking, I advise never ever pick one person, they can fall and fail t=you but the entire group will always be there regardless of changing faces.
