This final Petach of the section (53) acts as a short, quick bridge between the themes of the Breaking of the Vessels and the Tikkun.
Everything that was degraded at the time of the breaking of the vessels is to be repaired little by little through mankind’s input. This includes both the descent of the “hind parts” of Abba and Imma, which are the Partzuf equivalents of Chochma and Binah, as well as the breaking of the “hind” and “front” parts of the other Sephirot, i.e., Zeir Anpin and Nukveh .
For everything that was lacking then, i.e., at the breaking of the vessels, began to be fulfilled at the time of the repair of Atzilut, Briah, Yetzirah, and Assiyah through Heaven’s input. But in the end everything will be fulfilled in the perfect repair that will come about in the ultimate future when God’s Yichud will be revealed (Petach 53).
