The Demonic Bible, previously on the Internet, now in print for the first time. This is the 4th revised Edition of the Demonic Bible by Magus Tsirk Susej, Antichrist, Servant and disciple of the Dark Lord, revealed to him by the spirit Azael, his Unholy Guardian Demon. This book contains rituals for Crossing the Gates of Hell and becoming one with the Forces of Darkness. It also contains rituals for the invocation of hundreds of demons and Dark Gods. This may possibly be the most evil book written.
I picked up the 3rd edition cheaply on ebay. Hardly the most evil book ever written, as the publicity blurb states. The text rambles a lot and some ritual elements are borrowed from classical occult works. If you are on the Left Hand Path it probably merits a place in your library.
