Part 2: At the root of all this we find the division into the Three Heads in Arich Anpin… As discussed earlier, the very governmental order based on Justice itself derives from Arich Anpin.
…while the Unknown Head, which is above them, is the root of the Receiver… This is the mystery of “A woman of valor is the crown of her husband” (Proverbs 12:4). …the Shechinah, the Indwelling Presence. This is the power of the Shechinah, which is called “a stone cast up to Eyn Sof” – for the Shechinah was first in thought, while the attributes – the other nine Sefirot – were drawn forth only for the sake of the Shechinah through the columns of Kindness-Judgment-Mercy. (Chessed-Gevurah-Tiferet are the root of the Sefirot of Justice while Chochmah-Binah-Daat come only to add to the flow of influence and Netzach-Hod-Yesod to transfer it).
