Which ritual? If what you mean the dedication ritual, the most important thing is your will and being true. Satan and His Demons know everything about you inside out.
Yes but I want to make it perfectly but really I dont know, but for now I will start watching some videos from youtube and soon I will do it my self, but I really want to do it with someone ?
It's not easy to find someone to work with you because we all know our enemy is everywhere.Maybe you can try ask Father Satan for a spiritual buddy you can learn to each other. For now, just stick with yourselves. If you need anything, hey, you have this group!
