Two Stages of Geula (Redemption): 1

Hashem remembered His Nation and with unbelievable miracles returned us to our land after a bitter Exile. Thank God for His kindness towards us that He took us from death to life, darkness to light, from subjugation to other nations to freedom in the Land of Israel which produces beautiful fruit to its returning children.
The Navi Yechezkel explains that Geula (Redemption) happens in stages. The first stage is the gathering of Exiles, which is analogous to bringing the limbs of the body close to one another so that they should be together. This is the concept of "And the bones came close, bone to bone (Ez. 37:7). A closeness akin to that of neighbors. This is what we experience now that we are gathered to our land and live in close proximity to one another and are no longer scattered to the fours winds of the heavens.
After this stage comes the life giving spirit; the Neshama that flows through the limbs to truly unite them. They are no longer a gathering of bones that are near each other. This is the real connection in which the individual identity of the limbs is subsumed to the creation of a complete being - a national life, a life with the Schechina.
These two stages are clearly explained in the verses about the Dry Bones:

 ז וְנִבֵּאתִי כַּאֲשֶׁר צֻוֵּיתִי וַיְהִי קוֹל כְּהִנָּבְאִי וְהִנֵּה רַעַשׁ וַתִּקְרְבוּ עֲצָמוֹת עֶצֶם אֶל עַצְמוֹ. ח וְרָאִיתִי וְהִנֵּה עֲלֵיהֶם גִּדִים וּבָשָׂר עָלָה וַיִּקְרַם עֲלֵיהֶם עוֹר מִלְמָעְלָה וְרוּחַ 

אֵין בָּהֶם

"And I prophesied as I was commanded, and there was a noise and the bones came close, bone to its bone. And I saw and there was growing upon them sinews and flesh, and they were covered by skin above, but there was no spirit in them."

Redemption & the Inner Torah

The Zohar and other Kabbalistic works are replete with comments indicating that in future times the prerequisite for leaving Exile will be that the the inner teachings of the Torah would have to be revealed in their fullest sense. Based on what we have written so far we can understand that this is due to the fact that Kabbalistic thought is the Torah of the Schechina. These are not teachings which relate only to few individuals or certain aspects of people, rather they are teachings that relate to the entire body - the essence of the Schechina. The Kabbalistic teachings come to educate people in how to focus their essential selves as part of the Schechina as opposed to individual work for one's own perfection.
Every aspect of Kabbalistic thought is directed towards לשם יחוד קודשא בריך הוא ושכינתיה, for the sake of the uniting the Holy One, Blessed be He and his Schechina, to focus on the rectification of the Schechina rather than on one's self individually. This concept is expressed as עבודת צורך גבוהה, namely that the most significant acts we can do, the ones that come from the deepest recesses of our souls are not distinct from the Schechina and the Nation, but are serving the entire Jewish Nation. This can be compared to a cell that serves the entire body and whose purpose is not self-preservation, but that of the entire corpus.
This is the life of גאולה, redemption, with the Jewish Nation on its land. A life of Inner Torah in which one is focused on the entire Schechina rather than on an individual cell alone. Redemption depends on achieving this consciousness which is why it is dependent on the Zohar and the revelation of Kabbalistic concepts.
