189. Three spaces exist in the inner space of the skull in which the brain resides, and a thin membrane covers them. It is not a heavy and thick membrane as by Atik Yomin. Therefore, this brain permeates and illuminates to 32 pathways OF CHOCHMAH, as it is written: "And a river went out of Eden" (Beresheet 2:10).
190. We have further learned that in the three spaces of the skull resides the brain OF ZEIR ANPIN, and from a spatial cavern a spring gushes forth to four directions. From that particular brain that resides in this space, 32 pathways of the spirit of wisdom emanate.
191. From the second space, another spring bubbles up and spreads, WHICH IS THE SECRET OF THE LEFT COLUMN CALLED BINAH, and fifty gates open up. From these fifty gates are united the fifty days of the Torah, MEANING ON THE FIFTIETH DAY OF THE COUNT OF THE OMER IN WHICH THE TORAH WAS GIVEN, the fifty years of the Jubilee, 50,000 generations that the Holy One, blessed be He, will refresh his spirit in them and dwell in.
192. From the third space, thousand of thousand chambers and foyers emanate within which Da'at rests and resides. This space is situated between the other two spaces, MEANING IT IS THE CENTRAL SPACE BETWEEN THE RIGHT AND LEFT CAVERN SPACES. All these chambers are replenished from both directions, FROM RIGHT AND LEFT, as it is written: "And by knowledge (Heb. Da'at) are the chambers filled" (Mishlei 24:4). These three SPACES, WHICH ARE CHOCHMAH, BINAH AND DA'AT, permeate the whole body to this direction and that direction. The entire body is linked to them and the body is attached to them in all their aspects. And they permeate and exist throughout the entire body.
