Well, there are some questions that should be asked so maybe we can get a better idea of what the situation is. They should also give you an idea of what you may want to do to get where you want to be.
Do you meditate (in any way)?
Do you feel drawn to any particular entity/demon/etc?
Why do you want to talk to them, instead of using the a simple petition or Simple Evocation Ritual?
Are drawn towards Demonolatry or not?
How long have you been doing your practice?
What are your short, medium, and long-term goals with your practice or specific abilities?
Let’s start with that.
