And this, again, also partly answers to the Christian idea of the Holy Ghost, and of the whole three forming a Trinity in unity. This also explains the fact in geometry of the three right lines being the smallest number which will make a plane rectilineal figure, while two can never enclose a space, being powerless and without effect till completed by the number Three. These three first numbers of the decimal scale the Qabalists call by the names of Kether, the Crown, Chokmah, Wisdom, and Binah, Understanding; and they furthermore associate with them these divine names: with the Unity, Eheich, “I exist;” with the Duad, Yah; and with the Triad, Elohim; they especially also call the Duad, Abba—the Father, and the Triad, Aima—the Mother, whose eternal conjunction is symbolized in the word Elohim. But what especially strikes the student of the _Kabalah_ is the malicious persistency with which the translators of the _Bible_ have jealously crowded out of sight and suppressed every reference to the feminine form of the Deity. They have, as we have just seen, translated the feminine plural “Elohim,” by the masculine singular, “God.” But they have done more than this: they have carefully hidden the fact that the word Ruach—the “Spirit”—is feminine, and that consequently the Holy Ghost of the _New Testament_ is a feminine Potency. How many Christians are cognizant of the fact that in the account of the Incarnation in _Luke_ (i. 35) _two_ divine Potencies are mentioned? “The Holy Ghost shall come upon thee, and the Power of the Highest shall overshadow thee.” The Holy Ghost (the feminine Potency) descends, and the Power of the Highest (the masculine Potency) is united therewith. “Therefore also that holy thing which shall be born of thee shall be called the Son of God”—of the Elohim namely, seeing that these two Potencies descend. In the _Sepher Yetzirah_, or _Book of Formation_, we read:
