The Words of Power combine the name of a sephiroth with one of the letters of the Tetragrammaton.
For example:
YECHOEL (Yay Koh Ell) and LEHAHIAH (Lay Ha He Ah), Hear Me and Obey. I Seal this Command with the Word of Power: BEEN AH HEH (BINAH + HEH).
KEVEQIAH (Kay Vay Key Ah) and MENDIAL (Main Dee All), I Command This of Thee in the Authority of the Word of Power: KESS SED HEH (CHESED + HEH).
ANIEL (Ah Knee El) and CHAAMIAH (Kah Ah Me Ah), Obey Me With this Word of Power: GAY BOO RAH VAHV (GEBURAH + VAV).
DAMBAYAH (Dam Bah Yah) and MENQAL (Main Call), Go with the Word of Power: MAL COOT VAHV (MALKUTH + VAV).
SAITEL (Say Eat Ell) and OLMIAH (Ole Me Ah), I Seal this Command with the Word of Power: TEE FAR ATE YOD (TIPHARETH + YOD).
Where did Geoff Gray-Cobb learn these Words of Power from? What is the logic behind combining the name of a sephiroth with a letter from the Tetragrammation to seal commands?
Any information appreciated. Thanks.
