Part 10 · Chapter 48

Now, supernal Bina and supernal Aba are two names: Aba is called HaVaYaH of AB, filled with Yudin, and Ima is called Ehyeh of the Yudin, whose gematria is 161. And behold, the posterior of Bina, although it has ten Sefirot within it, the aspect of Elokim that is in her posterior, as mentioned, is not distinguished or revealed in her except in the posterior from her midpoint downward, which is from her chest, being the four Sefirot Tifferet, Netzah, Hod, and Yesod.
