Hello all and Happy pi day 3.14

My question is, what is this "higher power" mentioned about in the second best selling book in the world, Alcoholics Anonymous (AA)? Scattered throughout the book they ellude to God. Assuming that people will know that they are talking about something that could and would change their lives, if it were sought. Now I've seen first hand what people's lives has turned into because of addiction. No one signs up to be a homeless drug addict turning tricks and sexual favors for just 1 more hit. Is there not something more going on than just chemical reactions? I have witnessed hundreds of seemingly hopeless cases go through a transformation due to a spiritual reformation. There are countess millions of these stories from all over the world. Not to mention the "real ones" who have had experiences of God through out time. So can we conclude that this is a wide spread delusion that provides incredible and undeniable results? Or is there something more going on here than meets the eye? Because it really seems impossible that a couple of Alcoholics got together and wrote a 164 page book on God. And within 70 years it became the second best selling book on the planet, second only to the Bible? Freeing millions from some kind of spiritual slavery. It would be hard to say that something wasn't giving them Devine help. It was never about book sales or religion, it is a message that frees people from bondage. What "power" can do such things?
