…within their Malchut – which is called the back parts of their Netzach-Hod-Yesod… When we speak of Netzach-Hod-Yesod we actually mean Malchut behind Netzach-Hod-Yesod, because that is where its place is, and Netzach-Hod-Yesod are drawn after Malchut because their role is to channel influence thereto. Thus when we say Netzach-Hod-Yesod we really mean Malchut behind Netzach-Hod-Yesod and Netzach-Hod-Yesod with it.
For the Chariot is so arranged that Malchut is attached behind Tiferet, since the four key Sefirot are Chessed-Gevurah-Tiferet-Malchut. Netzach-Hod-Yesod emerge from Tiferet only for the sake of Malchut – to connect it to Tiferet – and accordingly they are called the pillars of Malchut, “Yachin” and “Boaz”. (This makes it possible to reconcile sources that refer to Israel Sabba-Tevunah as Malchut of Abba and Imma with those that refer to them as Netzach-Hod-Yesod of Abba and Imma.)
