This is the essential underlying governmental order that progressively brings complete perfection. As you have already heard, the different interconnections between MaH and BaN repair all damage and deficiency. Accordingly this is the essential underlying governmental order, and it is therefore necessary for Arich Anpin to stand under and be subject to it in all aspects. (Through the rule of Mazal – the Unknown Head – the overall service required of man is divided and allocated among the different souls according to what is needed to repair the damage, and the reward is measured accordingly.) (To summarize: All the Partzufim of Atzilut stand under the rule of Yesod and Malchut of Adam Kadmon in order to be governed in accordance with the repair instituted through the Balance, i.e. the repair of male and female through the interconnections of MaH and BaN.
Therefore Arich Anpin, the root Partzuf of Atzilut, clothes the seven lower Sefirot of Atik, which are governed through the Balance rooted in the Unknown Head – the first three Sefirot of Atik. The seven lower Sefirot of Atik are thus governed according to the principle of right and left, which are rooted respectively in Yesod and Malchut of Adam Kadmon. However, in terms of the developmental chain, Atzilut emerges from the branches of Adam Kadmon, i.e. from the radiance of the face of Adam Kadmon.)
