Part 2: Accordingly Daat can spread further than all the other Mental Powers. The spread of Daat comes about through the spread of the Five Kindnesses to all the Sefirot of Zeir Anpin and of the Five Strengths to those of Nukva, as will be discussed in due course (see Opening 126).
For the other Mental Powers… When we consider the way things are ordered in the light of our discussion above, we can see that once Abba and Imma are engrafted in Zeir Anpin’s Chochmah and Binah there is no need for them to spread. It is enough that they are present and …remain within their vessels since it is enough that they exist in Zeir Anpin… – for this is the way of the Mental Powers when they are present – …and stand in their respective columns... Certainly all aspects of Abba incline to the right and all aspects of Imma to the left, and these two therefore remain in their vessels according to the law of the Mental Powers. Since they are higher lights that come to direct Zeir Anpin, they are too exalted to function without being clothed in a vessel, and must therefore remain hidden and concealed. This is why they are present in a garb – each in its own column – in the vessels of Netzach and Hod of Abba and Imma respectively.
