Sometimes you go to a conference, and there is a corridor with multiple doors. It looks like each door is going to lead into a different room. Actually it leads into the same hall. You might have to go in through the door you’re assigned. But once you get in you can sit where you want, and wherever you sit, what you hear will be the same.
It’s like that with twelve-step fellowships. Each door is different but the hall is the same.
