Following our general explanation of the repair of Zeir Anpin and how his lights expand, we will now go into further detail about one light that has to expand more than the others.
The proposition consists of two parts. Part 1: The essence… This presents the concept of Daat. Part 2: Accordingly Daat can spread… This explains why Daat spreads further than the others.
Part 1: The essence of the entire governmental order of Zeir Anpin lies in Daat… As discussed earlier, the governmental order is arranged in such a way that Zeir Anpin – the Six Directions – is the root of all the creations (see Opening 115). Zeir Anpin includes all the proper attributes with which to govern all the different creations. Nevertheless, this is not sufficient for the governmental order to be complete. For Zeir Anpin to fulfill his purpose, Abba and Imma must be engrafted in him. This is accomplished through the two Mental Powers of Chochmah and Binah, each of which makes preparations for the repairs required in Zeir Anpin in order to bring the governmental order to perfection. Chochmah and Binah make the preparations, while Daat carries them out. Indeed the true gain accruing to Zeir Anpin from this engrafting in him of Abba and Imma is his Daat.
