So you were attacked? Well, let me lighten your burden.
In my sovereignty I send away any incorporeal entity that dares to bother you. Leave the poor thing alone, he has obviously got enough demons of his own.
Did that help?
Now if you are so experienced, what on earth gave you the idea that you can control individual beings that are out of reach of your level of existence? Evil spirits only feed the evil in yourself. Good spirits are far and few because humans are per definition partially evil. That is where your corporal body comes from. Now educate yourself, stop asking silly things, and don't mess with what you cannot control, which is, in most (or rather all...) cases, your own mind. You are scaring yourself, only attracting more "evil".
