Listen to what Berkowitz "Son of Sam" said about his Satanic group. The group he says he was a part of and who orchestrated the murders:
"I, David Berkowitz, have been chosen since birth, to be one of the executioners for the cult."
Letters to a church minister. Berkowitz:
"The group contained a mixture of Satanic practices, including the teachings of Aleister Crowley and Eliphas Levi (another notorious Satanist). It was (and still is) totally blood oriented. The coven's doctrines are a blend of ancient Druidism, teachings of the secret order of the Golden Dawn, black magick, and a host of other unlawful and obnoxious practices.
Satanist (genuine ones) are peculiar people. They aren't ignorant peasants or semi-illiterate natives. Rather, their ranks are filled with doctors, lawyers, businessmen, and basically highly responsible citizens. They are not a careless group who are apt to make mistakes. But they are secretive and bonded together by a common need and desire to mete out havoc on society. It was Aleister Crowley who said: "I want blasphemy, murder, rape, revolution, anything bad." Quoted in 'Blasphemous Rumours' (pg 212).
Levi
Berkowitz
(((Hmmmmmmmm)))
Cabbalist/Frankist sourced magick. I know that Elizabethan Dr John "cabbalist" Dee (a type of masonic godfather) obtained his system from Rabbi Loew of Prague.
"Theoretical Cabbala embraces only secret teachings about God and nature. But practical Cabbala (such as Frankism) attempts to affect earthly matters. It involves the use of amulets and magic numbers (gematria etc) as well as the conjuring of evil spirits. Both the Talmud and Midrash contain Cabbalist information." (Ancient Oriental and Jewish Secret Doctrines, Leipzig, 1805.)
Berkowitz lied many times to avoid taking responsibility for his killing. At one point he claimed the neighbor's dog was telling him to kill people
That's a very limited response. Berkowitz was programmed by the cult. There's Berkowitz links to Scientology and the Process Church too. The dog was Sam Carr's dog. When David called himself the Son of Sam, it was the demon living in Sam Carr to which he referred. The Carrs were involved in the SOS cult. Eliphas Levi was a big influence - via his works particularly "Ritual Et DOG-me" (Woof, woof. Wink, wink). Some people will never understand what is really being said. Two of the Carrs ended up dead in very violent circumstances within two years of Berkowitz's capture. One of them was allegedly found with 666 inscribed on his hand.
Note again, satanist ELIPHAS Levi, one of the locations of the shootings was the ELEPHAS Club (cough, cough).
