“In the Sephir Yetzirah, the Kabbalistic Book of Creation, the Divine Substance is represented as having alone existed from the eternity, boundless and absolute; and as having emitted from itself the Spirit.
“One is the Spirit of the living God, blessed be his Name, who liveth forever! Voice, Spirit and Word, this is the Holy Spirit.”
And this is the Kabbalistic abstract Trinity, so unceremoniously anthropomorphized by the Christian Fathers.
From this triple ONE emanated the whole Kosmos. First from ONE emanated number TWO, or Air, the creative element; and then number THREE, Water, proceeded from the air; Ether or Fire complete the mystic four, the Arba-il.
In the Eastern doctrine Fire is the first Element – Ether, synthesizing the whole (since it contains all of them).”
