6. “And who sustains the world etc.” And who is that who sustains the world and causes the Patriarchs to be revealed? It is the sound of children engaged in the Torah, and on account of these children of the world, the world is saved. Corresponding to them, it is stated: “We will make you circlets of gold” [Song of Songs 1:11] – these are children, lads, and youngsters, as it is stated: “And you shall make two cherubim of gold” [Exodus 25:18].

Explanation: The “children of the world” are the brains of the back that were mentioned just above, which are called the “small face.”¹. Likewise, the “children of the world,” as well as the “children, lads, and youngsters” [refers to the brains of the back]. The aspect of their fusion in this state is called “the sound of children engaged in the Torah.” This is the mystical meaning of the “circlets of gold,” and the mystical meaning of the “two cherubim,” which are the “small face,” without which these brains of ḥaya, which are drawn through the mystical meaning of the incorporation of right in left, would not be received in the Nukba whatsoever. All of this was explained just previously. This is why [Rabbi Shimon] states: “Who is that who sustains the world,” i.e., at the time of increase of the kelippot, which have the power to destroy the world as in the days of the flood. There is no remedy [for this destruction] except by drawing the brains of ḥaya in the mystical meaning of the rainbow in the cloud, as stated, since through this, “the world is saved.” And who is that who sustains and saves the world at that time, “and causes the Patriarchs to be revealed,” causing the manifestation of Ḥesed, Gevura, and Tiferet in the mystical meaning of the brains of the head, when Ḥesed, Gevura, and Tiferet become Ḥokhma, Bina, and Da'at of ḥaya? [Rabbi Shimon] says that the cause of all this is “the sound of children engaged in the Torah,” that is, the brains of the back, which is the mystical meaning of the sound of the children and the circlets of gold.
