No, you have nothing to expect when you do the ritual, when I did it I felt nothing, as my soul was sealed.
Don’t worry it will work, no matter what, this ritual has nothing to do with your own capabilities or abilities, but with Satan’s, and he is incredibly powerful, he will perceive it no matter what?
Oh, so you don’t want it to be a lifetime thing?
You are free to leave when ever you feel like it, Satan doesn’t force his people to stay, however, when you leave him, he will leave you as well, for as long as you decide to be alone. People are really lucky Satan is as great as he is, I wouldn’t accept people back once they left.
Karma describes energy that clings on your soul and manipulates you in a certain way, so we have to get rid of negative karma, we do this by cleaning.
All religions other people know got perverted and twisted to misguide and harm spiritual people.
