Let's start with
what not to do:
I get it, summoning a Demon sounds very cool. Can you imagine having a Demon appear to do and do what you ask of him? But expectations and reality are different things.
If you are new and you have no previous spiritual experience and you have not done the Dedication ritual, summoning a Demon can go anywhere from disappointing to frightening. If you are not a natural clairvoyant or have not developed your astral senses you will not see or feel anything at all. If you have not Dedicated yourself you might even get attacked by some enemy being trying to prevent you from contacting any of our Gods. The worst thing is some people, particularly those who have Christian ties have these scary experiences and think that a Demon did these to them and turn back to Jeezus and the Christian hoax. I'm not saying that this will
surely happen, but there is a small possibility.
Also for summoning a Demon you need to have a good reason. Just being lonely and wanting some spiritual being to talk to, or trying to see if it works aren't good reasons and the Demon will ignore you.
