The Union of Tohu and Tikun - The Primordial Kings, Their Descent, and Salvation by Yosef HaTzadik

BS"D

אלה תולדות יעקב יוסף בן שבע עשרה שנה

The stories of the fathers are a hint for the sons.  In the process of divine revelation symbolized by the stories of our fathers, Avraham, Yitzchak, and Yakov, the process of Yakov is the process of divine revelation internally within the physical and material world, through the aspect of Yakov, and Israel.

Kabbalistically, in the construction of the Face of Yakov, corresponding to the Partzuf of Zeir Anpin, you have three "stages" - the construction of the Keter of Zeir Anpin (mainly Arich Anpin and its source in Radla), the construction of the "Body" of Zeir Anpin, 6 dimensions in 2 sides, the 12 diagonal lines connecting the 10 Sefirot), and the Yesod of Zeir Anpin (as the Yesod includes the Keter, as a drop of semen contains the absolute DNA essence of the father).

This third aspect, the aspect of the Yesod is called Tzadik and is the mystical secret of Yosef HaTzadik.  It is the Man of Israel, and through the study of Torah (Daat and Tiferet, all the Sefirot aligned on the middle column of Truth), this Man of Israel manifests the revelation of G-dliness (Keter) within all the worlds, until and including the physical and material world.

Hence in the story of Yakov, we see this entire structure.  The exile from his father's house (symbolizing the exile of the Jewish Nation into the 2,000 year exile of Edom preceding the true and complete redemption by Moshiach), and into the work with Lavan, which in Kabbalah represents the dimension of Keter - above and removed from the Worlds.  With the heap of stones Yakov had constructed a passable division between the Worlds of Ein Sof and making a "place" for the World of Atzilut (a great constriction from the Worlds of Ein Sof).  However, this membrane allows passage from one dimension to the other, which makes it possible for the World of Atzilut to exist and yet draw down revelation of the World of Ein Sof within Atzilut (and through the process of construction of the entire World of Atzilut - corresponding the construction of the Face of Yakov above - the remaining 3 worlds of Beriya Yetzira and Asiya come into being).

The next process of Yakov is its core "mission" - the refinement of Esav.  Kabbalistically this means the rectification of the Primordial Lights of Tohu which fell during the Breaking of the Vessels in the World of Tohu.  These sparks are the source of all material fortune and pleasure and when they fell they created this coarse material and physical world where G-dliness is completely "concealed" by the coarseness of material existence.  This concept has parallels in all kabbalistic processes, in the soul, in the daily prayers and kavanot, and literally every dimension of Kabbalah this process represents the mission and goal of humanity.

Yakov's mission is to refine the coarseness of the material world, through the Torah and Mitzvot, and hence reveal within the finite physical world, the World of Ein Sof.  This is the key to the redemption, etc.  In order to receive the Torah, the Jewish Nation had to descend into Egypt and be redeemed openly by the divine revelations of the 10 plagues, splitting of Yam Suf, and the giving of the Torah.  Once Israel has the Torah, which of course corresponds to Yakov, Tiferet of Zeir Anpin, which is the garment of the Chochma Stimaa of Arich Anpin in which is garbed Or Ein Sof Boruch Hu).  In order to receive Moshiach, Israel went into a 2,000 year exile, after the destruction of the Second Temple, into the exile of Edom - which is Esav.  This is in order toc omplete the rectification of these Lights of Tohu, which are called the 288 Sparks of Tohy, which fell into the material world.  The Roman empire destroyed the Temple and Esav absorbed Yakov.  The Jewish Nation had a mission - fulfill the Torah and Mitzovt through complete and real self sacrifice, while the Western World, the Common Era, is born out of the ashes of the Holy Temple in Jerusalem.

Two religions will be born - Xtianity from Esav and Islam for Yishmael.  Both will have a place in the World to Come, but both must go through the process of refinement of Civilization.  And for 2,000 years the "modern world" has evolved.  Until now, in the End of Days, after the process of refinement of the 288 Sparks was completed through the toil of the Nation of Yakov in exile, and now Esav is ready to be refined, and through it the entire physical and material world will no longer conceal G-dliness but be a garment for it.
This is in the true and complete redemption of the Jewish Nation, the salvation of Yakov and rejoicing of Israel.

This is accomplished through the aspect of Yosef.  After Yakov refines Esav, marking the completion of the process of rectification of the world of Tohu through the 288 sparks which fell into Malchut - representing the physical and material world, the aspect of Yosef - Yesod becomes a conduit for the open manifestation of Ein Sof within the physical world.  This is Moshiach riding on the Donkey - on the Chamor, which means Chomer - matter.
