I am doing the one from EE and it has been a ride. Belial has opened a lot of doors and taught me a lot. I haven’t moved on to Azazel yet as I am still internalizing the lessons and dealing with the changes in my life. I thought I would do a month with Belial and then take a few weeks dealing with the life changes, but it has been 4 months and I am still learning from the lessons he taught me.
One thing that really was driven home for me is that the Demon will give you all or more than what you ask for. They assume that you can deal with it, or maybe they don’t care if you can deal with it. Either way just be cautious of what they teach. Belial taught me a binding that works wonders but he did not teach me the wisdom of knowing when to use it and on whom.
