The Seven Repairs of the Head are found in Arich Anpin, and this is because the entire government of Arich Anpin depends upon Atik… As you have already heard, the purpose of Atik is to bind all the Sefirot of Arich Anpin under Adam Kadmon and maintain them in the state of Balance. (This is through the Head of Atik, which contains the initial interconnection of MaH and BaN – see Opening 96.)
For this reason the seven lower Sefirot of Atik rule in the Head of Arich Anpin through the various particular repairs therein deriving from Atik. It is in the place where they first rule – in the Head – that this repair must be carried out, and it then extends to the entire Partzuf.
