After reading it completely for the first time I seem to remember experiencing a quite intense, mixed, and, in some ways, conflicting set of emotions.
I felt happy that I had just found out that indeed I was a Satanist, as I had suspected, and that in someway I had found my 'Home' after years of exploring Buddhism and Paganism.
On the other hand I remember feeling a sense of fear - How would I use this new found knowledge, How would it affect my interactions with my family and friends, What would they do if they found out?
I also felt excited, as I realised that this new found wisdom was the key I had been searching for that could unlock the dormant potentialities I knew lay within me, but had never had the balls or courage to tap into....
I still try to reread it regularly, and each time pick up something new. I started another run through of it a couple of weeks ago and this time am deliberately taking it slowly, sometimes only reading a section every few days, which is a different approach for me - all previous readings of it were done cover to cover in a few days max. This change of reading style was a conscious choice just to see if ruminating over small sections at a time yealded any different insights!
