Hello,

I have a few questions. Please excuse me for my broken English.

I never evoked a Goetia-demon, but I am very interested in the literature etc.

Is it harmful/dangerous to put a seal from a Goetia-demon (with a good nature) under my pillow to make contact with this demon in my dream?

My second question is if it is bad idea to put a seal from a Goetia-demon (again good nature) on my altar for candle-magick. The advice in my book is to put a statue or picture from a god or a symbol, like an ankh.

Thank you for reading.
