Daf 63b (דַּף ס״ג ע״ב)
In the mystery of the Thought that remembered the Tzaddikim [Righteous Ones] who would exist in the world (בְּסוֹד הַמַּחֲשָׁבָה שֶׁזָּכַר בַּצַּדִּיקִים שֶׁיִּהְיוּ בָּעוֹלָם), in the mystery of, “Yisrael arose in Thought” (בְּסוֹד יִשְׂרָאֵל עָלָה בַּמַּחֲשָׁבָה), therefore it says, “In the mystery of Thought” (לָכֵן אוֹמֵר בְּרָזָא דְּמַחֲשָׁבָה), “Vayomer [And He Said] now gave birth; that Heikhal [Palace] brought forth from what had been removed from the Holy Seed, and brought forth silently, and that which was born was heard outside, but the One who brought it forth brought it forth silently, so that it was not heard at all” (וַיֹּאמֶר הַשְׁתָּא אוֹלִיד הַהוּא הֵיכָלָא מַה דְּאִתְעֲדֵי מִזַּרְעָא דְּקֹדֶשׁ וְאוֹלִיד בַּחֲשַׁאי וְהַהוּא דְּאִתְיְלִיד אִשְׁתְּמַע לְבַר מָאן דְּאוֹלִיד לֵיהּ אוֹלִיד בַּחֲשַׁאי דְּלָא אִשְׁתְּמַע כְּלָל).
Its explanation is: that Heikhal [Palace], namely the Malkhut, which is the Heh of the Name B"N [Fifty-Two] (פֵּרוּשׁוֹ הַהוּא הֵיכָלָא שֶׁהוּא מַלְכוּת דְּהַיְינוּ ה׳ שֶׁל שֵׁם ב״ן), was like a Heikhal [Palace] for the Nekudah [Point] of the Yod (הָיָה כְּמוֹ הֵיכָל אֶל נְקוּדַת הַיוֹ״ד), in the mystery of the Kli [Vessel] surrounding the Ohr Penimi [Inner Light] (בְּסוֹד כְּלִי הַמַּקִּיף אֶת הָאוֹר הַפְּנִימִי), and this Heikhal [Palace], together with what was within it, revealed the activity of the Name Elohim, which comes from MNTZPKH, called Vayomer [And He Said] (הַהֵיכָל הַזֶּה עִם מַה שֶׁבְּתוֹכוֹ הָיְתָה מְגַלָּה פְּעֻלַּת שֵׁם אֱלֹהִים הַבָּא מִמּנצפ״ך הַנִּקְרָא וַיֹּאמֶר), from the mystery of the Primordial Avir [Air], called Avir Mem [Air–Mem] (מִסּוֹד אֲוִיר קַדְמוֹן הַנִּקְרָא אֲוִיר מ׳). When the Heh of B"N [Fifty-Two] created this Name Elohim from five letters in its own likeness and image in order to establish the Kelim [Vessels] (וּכְשֶׁבָּרְאָה הַה״ה שֶׁל ב״ן שֵׁם אֱלֹהִים זֶה מֵה׳ אוֹתִיּוֹת כִּדְמוּתָהּ וּכְצַלְמָהּ לְהַצִּיג הַכֵּלִים), it received abundance from the Holy Seed, called Abba (לָקְחָה שֶׁפַע מִזֶּרַע קֹדֶשׁ הַנִּקְרָא אַבָּא), which is the mystery of the Name A"B [Seventy-Two], called Kodesh [Holy], namely Chokhmah [Wisdom], as is known (שֶׁהוּא סוֹד שֵׁם ע״ב שֶׁנִּקְרָא קֹדֶשׁ שֶׁהוּא חָכְמָה כַּנּוֹדָע), which sent Above seven Ketarim [Crowns], seven Chokhmot [Wisdoms], and seven Binot [Understandings] from the mystery of the seventy Ketarim [Crowns] to the House of Yaakov (שֶׁשָּׁלַח לְמַעְלָה ז׳ כְּתָרִים וְז׳ חָכְמוֹת וְז׳ בִּינוֹת מִן סוֹד ע׳ כְּתָרִים לְבֵית יַעֲקֹב), and the three Heads were built (וְנִבְנוּ הַתְּלַת רֵישִׁין).
Its explanation is: through this Yod together with the union of the Heh, the five Partzufim [Configurations] were created, each with ten Sefirot (וּפֵי׳ שֶׁע״י הַיוֹ״ד הַזֹּאת עִם צֵרוּף הַה״י נִבְרְאוּ ה׳ פַּרְצוּפִין כָּל אֶחָד מִי׳ סְפִירוֹת), yet the Kol [Voice] had still not come into being, but existed only in potential within the unknown Malkhut (אַךְ מִכָּל מָקוֹם לֹא הָיָה נִבְרָא הַקּוֹל רַק הָיָה בְּכֹחַ בְּמַלְכוּת דל״א), namely Keter [Crown], where is the House of Elohim mentioned in the Alef of Ein [Nothingness], as we explained above (דְּהַיְינוּ כֶּתֶר אֲשֶׁר שָׁם הוּא בֵּית אֱלֹהִים הַנִּזְכָּר בָּאָלֶ״ף שֶׁל אֵין כִּדְפֵרַשְׁנוּ לְמַעְלָה), and the Kol [Voice] and the Dibbur [Speech], namely Ze'ir Anpin and Nukvah, were not heard outside (וְהַקּוֹל וְהַדִּבּוּר לֹא הָיוּ נִשְׁמָעִים חוּצָה דְּהַיְינוּ זְעֵיר וְנוּקְבֵיהּ), but only Thought in silence (רַק מַחֲשָׁבָה בַּחֲשַׁאי), namely Bereshit, that is, Keter [Crown] (דְּהַיְינוּ בְּרֵאשִׁית דְּהַיְינוּ כֶּתֶר), for before Arich Anpin, “What can you count?” (כִּי לִפְנֵי אֲרִיךְ מָה אַתָּה סוֹפֵר), therefore it says that this Heikhal [Palace] conceived from the Name A"B [Seventy-Two], which is the Head within the Garment (לָכֵן אָמַר שֶׁנִּתְעַבְּרָה הַהֵיכָל הַזֹּאת מִן שֵׁם ע״ב שֶׁהוּא הָרֹאשׁ שֶׁבַּמַּלְבּוּשׁ).
