The Alter Rebbe teaches about the ultimate purpose of creation being the dwelling of the Divine Presence specifically in this lower world — a theme directly tied to the Land of Israel as the dwelling-place of the Shekhinah and the site of the ultimate redemption and revelation.
וְהִנֵּה, מוּדַעַת זֹאת מַאֲמַר רַבּוֹתֵינוּ־זִכְרוֹנָם־לִבְרָכָה, שֶׁתַּכְלִית בְּרִיאַת עוֹלָם הַזֶּה הוּא – שֶׁנִּתְאַוָּה הַקָּדוֹשׁ־בָּרוּךְ־הוּא לִהְיוֹת לוֹ דִּירָה בַּתַּחְתּוֹנִים. וְהִנֵּה, תַּכְלִית הִשְׁתַּלְשְׁלוּת הָעוֹלָמוֹת וִירִידָתָם מִמַּדְרֵגָה לְמַדְרֵגָה – אֵינוֹ בִּשְׁבִיל עוֹלָמוֹת הָעֶלְיוֹנִים, הוֹאִיל וְלָהֶם יְרִידָה מֵאוֹר פָּנָיו יִתְבָּרֵךְ, אֶלָּא הַתַּכְלִית הוּא עוֹלָם הַזֶּה הַתַּחְתּוֹן, שֶׁכָּךְ עָלָה בִּרְצוֹנוֹ יִתְבָּרֵךְ, לִהְיוֹת נַחַת רוּחַ לְפָנָיו יִתְבָּרֵךְ, כַּד אִתְכַּפְיָא סִטְרָא אָחֳרָא וְאִתְהַפֵּךְ חֲשׁוֹכָא לִנְהוֹרָא – שֶׁיָּאִיר אוֹר ה׳ אֵין־סוֹף בָּרוּךְ־הוּא בִּמְקוֹם הַחֹשֶׁךְ וְהַסִּטְרָא אָחֳרָא שֶׁל כָּל עוֹלָם הַזֶּה כּוּלּוֹ, בְּיֶתֶר שְׂאֵת וְיֶתֶר עֹז וְיִתְרוֹן אוֹר מִן הַחֹשֶׁךְ, מֵהֶאָרָתוֹ בְּעוֹלָמוֹת עֶלְיוֹנִים, שֶׁמֵּאִיר שָׁם עַל יְדֵי לְבוּשִׁים וְהֶסְתֵּר פָּנִים, הַמַּסְתִּירִים וּמַעֲלִימִים אוֹר־אֵין־סוֹף בָּרוּךְ־הוּא שֶׁלֹּא יִבָּטְלוּ בִּמְצִיאוּת. וְנוֹדָע, שֶׁיְּמוֹת הַמָּשִׁיחַ, וּבִפְרָט כְּשֶׁיִּחְיוּ הַמֵּתִים, הֵם תַּכְלִית וּשְׁלֵימוּת בְּרִיאַת עוֹלָם הַזֶּה, שֶׁלְּכָךְ נִבְרָא מִתְּחִילָּתוֹ
It is a well-known Rabbinic statement that the purpose of the creation of this world is that the Holy One, blessed is He, desired to have an abode in the lower worlds. Clearly, the purpose of the hishtalshelut of the worlds and their descent, degree by degree, is not for the sake of the higher worlds, because for them this is a descent from the light of His Countenance, blessed be He. But the ultimate purpose [of creation] is this lowest world, for such was His will, blessed be He, that He shall have satisfaction when the sitra achara is subdued and the darkness is turned to light, so that the Divine light of the En Sof, blessed is He, shall shine forth in the place of the darkness and sitra achara throughout this world, all the more strongly and intensely, with the excellence of light emerging from darkness, than its effulgence in the higher worlds, where it shines through “garments” and in concealment of the Countenance, which screen and conceal the light of the En Sof, blessed is He, in order that they should not dissolve out of existence. It is well known that the Messianic Era, and especially the time of the Resurrection of the Dead, is the fulfillment and culmination of the creation of the world, for which purpose it was originally created.
