I was recently introduced to ACIM by someone I met on another forum. Both of us are seekers of spirtual growth, and organized religions don't do it for me. The friend has practiced for many, many years. I bought the book. I am doing the lessons, though I don't do one evey day. I'm reasonably intelligent, I can grasp the abstract, but sometimes this just eludes me. Every now & then I get a glimpse. Occasionally I understand that it is all illusion. But then I have to go to work, feed the cat, pay the bills. Nothing illusory about that.
I also live in the "Bible Belt". Somehow I don't think this would translate to the bleeding deacons around here. It's like having a secret.
