From here the developmental chain must descend level by level until it reaches the actual place of Kindness-Judgment-Mercy on the level of Zeir Anpin, as will be fully explained below with the help of Heaven (see Openings 105 & 114). This is what is discussed in the Idra Zuta, where the intention is not to set out the repairs of Arich Anpin but only to show that they are also all consistent with Arich Anpin’s being the root of Zeir Anpin, as explained there explicitly. (This is why it is only in the Idra Zuta that Abba and Imma are mentioned, since their role is to transfer the influence descending from Arich Anpin to Zeir Anpin.)
