In the light of this we must understand the Partzufim of Atzilut, their arrangement and the way they rule, as a single Tree that constitutes a complete order of government as required for the creations. However, prior to all of Atzilut there is this connection of MaH and BaN. (“The coupling of Yesod and Malchut of Adam Kadmon” – Etz Chayim Shaar 3 ch. 2. This may refer to the connection between the Line and the Residue, which is the root of all that is destined to exist.) For the Partzufim were produced in accordance with the way that MaH and BaN interconnect. We must therefore say that first there must exist this root of the governmental order which arranges these interconnections, and only afterwards the governmental order itself comes forth through the Partzufim.
