Im new to this forum and have been studying the Necronomicon. I have roots in the Nordic/Shaman practice along with experience in Chaos magick and Hermetics....
To get to the point I could not help but notice the very valuable techniques of which can be applied to this system via the Czech Mage Franz Bardon. I have studied Bardon and HIGHLY recomend "Initiation into Hermetics". There may be a little dogma here or there but pay no attention... Of all the hundreds of books I have owned and have, Bardons system is very plain and easy to understand. He cuts the fancy talk and wierd poetry out and gets to the point of being and doing. Once one has tried his techniques you will understand what I am talking about.
You can find a PDF of Initiation into Hermetics (easy to find)
I put it here as the "techniques" are relevant to using the Necronomicon. The techniques work very very well. Basic foundations to give oneself a safety net whilst walking a tightrope
I understand your concern for topic related discussion...
