"Blessed hearts, you have heard that name of God as JEHOVAH, I AM THAT I AM. This principle of being is the white fire core of your own mighty I AM God Presence. When qualified by the name of the Ancient of Days, it truly expands, geometrizes, and extends dimensions of being throughout the quivering cosmos. And even the stars are agitated at the pronouncement of his name."
"The name of God, then, has its progressions from Elohim out of solar fires and hierarchies. But the name that is the central diadem of the entire Great White Brotherhood is truly Sanat Kumara—Sanat Kumara, known in other manifestations as Karttikeya and the Word itself, as the Faithful and True." - Enoch Pearls of Wisdom vol. 24, no. 5.
