I'm sure you can guess what happened next. I actually cursed myself for not reading it the first time I encountered it.
Obviously your "process" started already when you first saw the book though you did not read it and recognize your Satanism in first place.
I see that we are naturally born this way, but we all have to do some job to find it out who we are and where should we stand. Some people find it easy way, some harder. Still cause Satanism supports us to be the way we naturally are it does not change so much in oneīs nature. For that reason cursing yourself for letting the book off your hands without reading it is counter productive way to see this issue. You have read the book later and are member as a result of that. Everything else is just steps leading to the point you are standing today!
