Rav Moshe Cordovero dedicates the final chapter to Malchus — the Shekhinah — describing how she receives from all the upper sefirot and channels their influence into the world. Her enduring presence and inexhaustible receptivity reflect the Netzach quality of eternal sustaining power.
בלילה יתקשר עם המלכות: וְהִתְחִיל מֵהַלַּיְלָה עֵת שְׁכִיבַת הָאָדָם עַל מִטָּתוֹ, וַהֲרֵי הַשְּׁלִיטָה הִיא לַיְלָה מִדַּת הַמַּלְכוּת, וְהוּא הוֹלֵךְ לִישֹׁן, הַשֵּׁנָה הִיא כְּעֵין מִיתָה וְאִילָנָא דְמוֹתָא שָׁלְטָא, מַה יַעֲשֶׂה, יְתַקֵּן וְיַקְדִּים לְהִתְקַשֵּׁר בְּסוֹד הַקְּדֻשָּׁה דְּהַיְנוּ סוֹד מִדַּת הַמַּלְכוּת בִּבְחִינַת קְדֻשָּׁתָהּ, וְלָזֶה יֵלֵךְ עַל מִטָּתוֹ וִיקַבֵּל עֹל מַלְכוּת שָׁמַיִם שְׁלֵמָה בכונת הַלֵּב. קָם בַּחֲצוֹת לַיְלָה יִטּוֹל יָדָיו מֵהַקְּלִפָּה הַשּׁוֹלֶטֶת עֲלֵיהֶם וְיַעֲבִיר רָעָה מִבְּשָׂרוֹ וִיבָרֵךְ, וִיתַקֵּן הַשְּׁכִינָה בְּעֵסֶק הַתּוֹרָה, וְעַל זֶה נֶאֱמַר עָלֶיהָ (מִשְׁלֵי ו, כב): "בְּשָׁכְבְּךָ תִּשְׁמֹר עָלֶיךָ" מִן הַחִצוֹנִים "וַהֲקִיצוֹתָ הִיא תְשִׂיחֶךָ" . וְתִתְקַשֵּׁר עִמּוֹ וְהוּא עִמָּהּ, וְיִתְעַלֶּה דְּיוֹקַן נִשְׁמָתוֹ בְגַן עֵדֶן עִם הַשְּׁכִינָה הַנִּכְנֶסֶת שָׁם עִם הַצַּדִּיקִים, וְהַתִּפְאֶרֶת יָבֹא שָׁם גַּם הוּא לְהִשְׁתַּעֲשֵׁעַ עִם הַצַּדִּיקִים וְעִמּוֹ בְּחֶבְרָתָם, שֶׁכֻּלָּם מַקְשִׁיבִים לְקוֹלוֹ. הֲרֵי מַמָּשׁ נָסַע עִמָּהּ מֵהַמִּיתָה וְהַשֵּׁנָה אֶל סוֹד הַחַיִּים הָעֶלְיוֹנִים וְנִקְשָׁר בְּסוֹד גַּן עֵדֶן וְהִתְחִיל לְהִתְנוֹצֵץ עָלָיו אוֹר הַתִּפְאֶרֶת הַמִּתְנוֹצֵץ בְּגַן עֵדֶן עַל הַצַּדִּיקִים, וְכֵן פֵּרֵשׁ בְּפָרָשַׁת תְּרוּמָה (דַּף קל:). יָצָא מִבֵּית הַכְּנֶסֶת יְיַחֵד עַצְמוֹ מַמָּשׁ בַּמַּלְכוּת לְבַד, בְּסוֹד קַבָּלַת עֹל מַלְכוּת שָׁמַיִם, וְזֶהוּ תְּקוּפָתוֹ בַיּוֹם עִם תְּקוּפַת הַסְּפִירָה, וּלְעוֹלָם דָּבֵק בָּאוֹר הַשּׁוֹלֵט.
At night he [should] connect with Kingship: And he begins from the night, at the time that a man lies down on his bed. And behold the rulership is to Night, the trait of Kingship. And he goes to sleep - and sleep is similar to death, and the tree of death rules. What shall he do? He [should] repair and proceed to connect to the secret of holiness, which is the secret of the trait of kingship, from the aspect of its holiness. And so he [should] go on his bed and accept the full yoke of the Kingship of the Heavens with concentration of the heart. He gets up at midnight, [washes] his hands from the husk that is governing them, removes the evil from his flesh and recites a blessing. And he [should] repair the Divine Presence through the occupation with Torah. And about this is it stated (Proverbs 6:22), "When you lie down it will watch over you," from the external forces; "and when you awake, it will talk with you." And She will be connected to him, and he to Her. And the likeness of his soul will rise in the Garden of Eden with the Divine Presence that is entering there with the righteous ones. And Splendor will also come there to play with the righteous ones, and with him in their company - as they will all be listening to his voice. Behold, he has actually traveled with Her from death and sleep to the secret of the Garden of Eden and began to cause the light of Splendor, that sparkles in the Garden of Eden upon the righteous, to sparkle upon him. And so is it explained in [the Zohar,] Parshat Terumah (p. 130b). He exits the synagogue [and] unifies himself truly with Kingship alone, through the secret of accepting the yoke of the Kingdom of the Heavens. And this is his strength during the day, with the strength of the Sefirah. And he [should] always cling to the Light that is ruling.
