TETRAGRAMMATON
“But Moses said to God, ‘If I come to the Israelites and say to them, “The God of your fathers has sent me to you,” and they ask me, “What is his name?” what shall I say to them?’ God said to Moses, ‘I AM WHO I AM.’ He said further, ‘This is what you are to say to the Israelites: “I AM has sent me to you.” -Exodus 3:13-15
The Tetragrammaton is used in Luciferian/Satanic and Occult Magick as one of the ineffable names of power. “Tetragrammaton” means “four-letter name.” The Tetragrammaton consists of four Hebrew letters, YHVH (Yod, Heh, Vau, Heh). The exact pronunciation of the Tetragrammaton is not universally agreed on, however, it is pronounced as “Yahweh" by the the Christians who have fallen for the Tetragrammaton deception.
High level Freemason Aleister Crowley, who was the most notorious Satanist of the 20th century, loved the Tetragrammaton, and considered it so powerful that it should only be used very carefully:
"Such a Word should, in fact, be so potent that man cannot hear it and live. Such a word was indeed the lost Tetragrammaton. It is said that at the utterance of this name the Universe crashes into dissolution. Let the Magician earnestly seek this Lost Word, for its pronunciation is synonymous with the accomplishment of the Great Work."
