“Most significant in this regard is a passage of his Sefer ha-Hokhmah, a commentary on the mystical forty-two-letter name of God. In a text on the tefillin of God, which are composed of the prayers (tefilloth) of Israel, it is said of the crown (‘atarah), which by these prayers ascends from below to rest upon God’s head then to be called Aktariel, in thoroughly kabbalistic language:
“For the tefillah sits at God’s left like a bride by a bridegroom, and she is called the king’s daughter, sometimes she is also called, according to her mission [to those here below] daughter of the voice [the talmudic expression for the celestial voice that mortals sometimes hear]. Of this Solomon said [reinterpreting Proverbs 8:30]: And I was Shekhinah by him, and the name of the Shekhinah is ‘ehyeh [I was] and the word next to it [in the verse] can also be explained, according to the Targum, as “she became great.”
For she is called the king’s daughter because the Shekhinah is with him in his house and it is to this that reference is made [in Ps. 91:1] to the dwelling in the shadow of shaddai [sel, “shadow,” being taken here in the sense of ‘esel, “by”] which means: He has a shadow which is called “by him” and this is the tenth kingdom, malkhuth, and it is the mystery of all mysteries. And we know that the word sod, mystery, can be interpreted [by the method of letter-mysticism] as the word malkhuth.
On every side of the Shekhinah are the crowns of royalty. And she herself is 236,000 myriads of parasangs long [that is, she is the theophany of God upon his throne, as described in the Shi’ur Qomah]. . . . And she directs the world and is named angel of God by virtue [of this her] mission, but with her no separation [from God] takes place.
And of this the verse [Exod. 23:20] said: I am sending an angel before you. This is the Shekhinah. And it is in this sense that the sages explain the verse [Num. 16:4]: Moses fell on his face, that is, because the Shekhinah was [there], he prostrated himself before God. That is why the prophets saw the Shekhinah, which is emanated, as it is said in Sefer Hekhaloth that the Shekhinah dwells beneath the cherub, and [originally] angels and men saw it.
But when the generation of Enoch sinned, the Shekhinah ascended heavenward. As for the Creator and Master of the Shekhinah, he is hidden from all and has neither measure [as in the Shi’ur Qomah] nor likeness, and no eye saw him. . . . And this is the mystery of the crown and the mystery of the Shekhinah, and whoever has this knowledge has a part in the world to come, inherits both worlds, and is saved from the judgment of Gehenna and he is beloved above and cherished below.”
