The Shechina accompanied the Israelites in exile. And when the salvation comes it says Psalms 3:9
“לַיהוָה הַיְשׁוּעָה; עַל-עַמְּךָ בִרְכָתֶךָ סֶּלָה”
“Salvation belongs to YHVH; Your blessing be upon Your people! Selah.”
The Zohar explains that ‘Salvation belongs to YHVH’ because the Shechina will be free to be with him. The blessings that he provides for the Israelites give them support so they can go out of exile.
“וְשָׁב יְהוָה אֱלֹהֶיךָ אֶת-שְׁבוּתְךָ, וְרִחֲמֶךָ; וְשָׁב, וְקִבֶּצְךָ מִכָּל-הָעַמִּים, אֲשֶׁר הֱפִיצְךָ יְהוָה אֱלֹהֶיךָ, שָׁמָּה”
“then YHVH your God will restore you from captivity, and have compassion on you, and will gather you again from all the peoples where YHVH your God has scattered you”
At the end of the exile YHVH with his compassion will gather the Israelites from all the nations where he scattered them during the exile period. We are now experiencing the compassion period. The spread of Zohar studies around the world is part of this process. It helps remove the Klipot from the world and dig wells of Light.
The Baal Shem Tov (http://screen.com.ve/clientes/dailyzohardemodailyzohar.com/tzadikim/24-Rabbi-Yisrael-ben-Eliezer) made a soul elevation to the palace of the Mashiach:
I asked the Mashiach: “When will the Master come?”, and he answered: “By this you shall know:
In the time when your teaching will become public and revealed in the world, and your wellsprings will burst forth to the farthest extremes, that which I have taught you and you have comprehended, and they also shall be able to perform unifications and elevations as you, and then all of the klipot will cease to exist, and there shall be a time of goodwill and salvation.”
As we can see from the answer of Mashiach, among other things we need to be able to perform unification and elevation. Most of us cannot be like the Baal Shem Tov but we can definitely focus on Zohar studies that is the aspect of unification of upper and lower and give our souls spiritual elevation.
