…Abba and Imma are grafted into… The Mental Powers in Zeir Anpin are Chochmah-Binah-Daat, the light of the interior soul (פנימיות pnimiyut) contained within, as discussed in its appropriate place. The particular nature of Zeir Anpin’s Mental Powers derives from the way Abba and Imma are grafted into him in order to complete and perfect the governmental order in the proper way on the basis of Kindness-Judgment-Mercy (see Opening 113).
…and rule Zeir Anpin. It is through the rule of Abba and Imma over Zeir Anpin that these Sefirot of Chochmah-Binah-Daat are found in Zeir Anpin as a result of this engrafting. Their presence in Zeir Anpin testifies to the rule of Abba and Imma over him.
