Daf 39a (דַּף ל״ט ע״א)
And when (some say: Vav, Caf, Dalet) it descends below to the Tzaddik, it is called measure (וְכַד [ס״א ו׳ כ״ד] נָחִית לְתַתָּא לְגַבֵּי צַדִּיק אִתְקְרֵי שִׁיעוּר). And when it ascends above to the supernal Imma, it is called stature (וְכַד סָלִיק לְעִילָא לְגַבֵּי אִמָּא עִלָּאָה אִתְקְרֵי קוֹמָה). And the secret of the matter: “And they measured by the omer” - this is the supernal Shekhinta (וְרָזָא דְמִלָּה וַיָּמֹדּוּ בָעֹמֶר דָּא שְׁכִינְתָּא עִלָּאָה) (Exodus 16). For She is an omer for the skull (דְאִיהִי עֹמֶר לַגֻּלְגֹּלֶת), which is the skull of the head (דְאִיהִי גֻלְגַּלְתָּא דְרֵישָׁא). And the lower Shekhinta - She is the counting of the Omer (וּשְׁכִינְתָּא תַּתָּאָה אִיהִי סְפִירַת הָעוֹמֶר), in which one counts seven days, which are seven Shabbatot (דְּבָהּ מָנֵי שֶׁבַע יוֹמִין דְּאִינוּן שֶׁבַע שַׁבָּתוֹת). And in them are forty-two days of the six of each week (דְּאִית בְּהוֹן אַרְבָּעִין וּתְרֵין יוֹמִין דְּשִׁיתָּא דְכָל שָׁבוּעַ). And seven Shabbatot - behold forty-nine (וְשֶׁבַע שַׁבָּתוֹת הָא מ״ט) (some say: of Metatron [נ״א דמטטרו״ן]). ![]()

These are forty-nine pure aspects (דְּאִינוּן מ״ט אַנְפִּין טָהוֹר). “Hear, O Yisrael, Hashem our God, Hashem is One. Blessed be the Name of the glory of His kingdom forever and ever” (שְׁמַע יִשְׂרָאֵל יְהוָ״ה אֱלֹהֵינוּ יְהוָ״ה אֶחָד, בָּרוּךְ שֵׁם כְּבוֹד מַלְכוּתוֹ לְעוֹלָם וָעֶד). In them the lower Shekhinta is purified for Her Husband (דִּבְהוֹן אִתְדַּכִּיאַת שְׁכִינְתָּא תַּתָּאָה לְגַבֵּי בַּעֲלָהּ), in Her mikveh (בְּמִקְוְה דִילָהּ), of which it is said: “The mikveh of Yisrael is Hashem” (דְאִיהוּ מִקְוֵה יִשְׂרָאֵל יְהוָ״ה) (Jeremiah 17). And this is the measure of stature (וְאִיהוּ שִׁיעוּר קוֹמָה). For thus are the letters of mikveh - komah (דְּהָכִי אִינוּן אַתְוָון דְּמִקְוֵה קוֹמָה). And they are Mem closed, in this mystery (וְאִינוּן מ׳ סְתִימָא בְּרָזָא דָא). Nine points for every side (צִיוּר דְּתֵשַׁע נְקוּדִין לְכָל סְטַר). In the central point they are completed to forty seah (בִּנְקוּדָה דְאֶמְצָעִיתָא אִשְׁתַּלִּימוּ לְאַרְבָּעִים סָאִין). This is the measure of a mikveh (אִיהוּ שִׁיעוּרָא דְמִקְוֵה), in which the woman is purified for her husband (דְּבֵיהּ אִתְדַּכִּיאַת אִתְּתָא לְבַעֲלָהּ). And before she is purified, she must count seven days of purification (וְקֳדָם דְּאִתְדַּכִּיאַת, צָרִיךְ לְמַנָּאָה שִׁבְעָה יוֹמִין דְּדַכְיוּ), to complete in them the forty-nine pure aspects of Orayta (לְאַשְׁלָמָא בְּהוֹן מ״ט פָּנִים דַּכְיוּ דְאוֹרַיְיתָא). And in them are united the Written Orayta and the Oral Orayta (וּבְהוֹן אִתְחַבְּרַת אוֹרַיְיתָא דְבִכְתָב וְאוֹרַיְיתָא דִבְעַל פֶּה), on the day of Shavuot (בְּיוֹמָא דְשָׁבוּעוֹת). These are the two Partzufin of Adam (דְּאִינוּן דּוּ פַּרְצוּפִין דְּאָדָם). And the union of both is the womb (וְחִבּוּרָא דְתַרְוַיְיהוּ רֶחֶם), which is the 248 positive commandments (דְּאִיהוּ רְמַ״ח פִּקּוּדִין דַּעֲשֵׂה). And the secret of the matter: “Sanctify to Me every firstborn that opens every womb” (וְרָזָא דְמִלָּה קַדֶּשׁ לִי כָל בְּכוֹר פֶּטֶר כָּל רֶחֶם) (Exodus 13). For in this union of Shavuot all the positive commandments are brought near (בְּהַאי חִבּוּרָא דְשָׁבוּעוֹת מִתְקָרְבִין כָּל פִּקּוּדִין דַּעֲשֵׂה), “as the bones in the belly that is full” (כַּעֲצָמִים בְּבֶטֶן הַמְּלֵאָה) (Ecclesiastes 11).
And at that time, all the limbs receive through the channels, this one from that one (וּבְהַהוּא זִמְנָא, כָּל אִינוּן אֵבָרִין מְקַבְּלִין עַל יְדֵי צִנּוֹרִין דָּא מִן דָּא). This is what is written: “The loops shall correspond one to another, a woman to her sister” (הֲדָא הוּא דִכְתִיב מַקְבִּילוֹת הַלֻּלָאוֹת אִשָּׁה אֶל אֲחוֹתָהּ) (Exodus 26). And when they receive, all the Sefirot receive one from the other (וְכַד אִינוּן מְקַבְּלִין, כָּל סְפִירָאן מְקַבְּלִין דָּא מִן דָּא). And the angels below receive each from each (וּמַלְאָכִין לְתַתָּא מְקַבְּלִין דֵּין מִן דֵּין), as you say: “And they receive one from the other” (כְּמָה דְאַתְּ אָמַר וּמְקַבְּלִין דֵּין מִן דֵּין). And each one gives permission to his companion, to enter into the domain of his companion (וְכָל חַד וְחַד יָהִיב רְשׁוּ לְחַבְרֵיהּ, לְאַעָלָא בִּתְחוּמָא דְחַבְרֵיהּ), as you say: “And they give permission, each to the other” (כְּמָה דְאַתְּ אָמַר וְנוֹתְנִין רְשׁוּת זֶה לָזֶה). And who causes this? Yisrael, when they receive one from another (וּמָאן גָּרִים דָּא, יִשְׂרָאֵל כַּד מְקַבְּלִין דָּא מִן דָּא), whether in Orayta or in wealth (בֵּין בְּאוֹרַיְיתָא בֵּין בְּמָמוֹנָא). They cause Above to receive one from the other, and to bestow one to the other (גָּרְמִין לְקַבְּלָא לְעִילָא דָא מִן דָּא, וּלְאַשְׁפָּעָא דָא לְדָא). And all is by means of channels (וְכֹלָּא עַל יְדֵי צִנּוֹרִין). This is what is written: “Deep calls to deep at the sound of Your channels” (הֲדָא הוּא דִכְתִיב תְּהוֹם אֶל תְּהוֹם קוֹרֵא לְקוֹל צִנּוֹרֶיךָ וְגוֹ׳) (Psalms 42). And what do they say one to the other? Four of Your waters (וּמַאי אַמְרֵי דָא לְדָא, אַבַּע מֵימֶיךָ). “The voice of two companions I hear” (קוֹל שְׁנֵי רֵיעִים אֲנִי שׁוֹמֵעַ). And corresponding to them are two lips that are called streams of water (וְאִינוּן לְקִבְלַיְיהוּ תְּרֵין שִׂפְוָון דְּאִתְקְרוּן אֲפִיקֵי מָיִם). And who are they? Netzach and Hod (וּמָאן נִינְהוּ נֵצַח וָהוֹד), which are called watering troughs of the waters (דְּאִתְקְרוּן שִׁקְתוֹת הַמָּיִם). And both are watered by the channel, which is the middle pillar that includes all (וְתַרְוַיְיהוּ אִתְשַׁקְיָין עַל יְדָא דְצִנּוֹרָא דְאִיהוּ עַמּוּדָא דְאֶמְצָעִיתָא דִכְלִיל כֹּלָּא). And it is the covenant in which are included all the limbs of the body (וְאִיהוּ בְּרִית דִּכְלִילָן בֵּיהּ כָּל אֵבָרִין דְּגוּפָא). All the channels are watered from the letter Vav (כָּל צִנּוֹרִין אִינוּן אִתְשַׁקְיָין מִן אָת ו׳), which is the river that goes forth from Eden (דְּאִיהוּ נָהָר דְּנָגֵיד וְנָפֵיק מֵעִדֶן). And it is the channel that goes forth from the spring of water, which is Yod (וְאִיהוּ צִנּוֹר דְּנָפִיק מִמַּעֲיָנָא דְמַיָּא דְאִיהוּ יוֹ״ד). And from it spreads forth the Heh, which is the supernal sea (וּמִנֵּיהּ אִתְפַּשְׁטָא ה׳ דְּאִיהִי יָם עִלָּאָה).
And come and see: nine points are from Kamatz to Shuruk p1-11(וְתָא חֲזִי תֵּשַׁע נְקוּדִין אִינוּן מִן קָמֵ״ץ עַד שׁוּרֵ״ק). And all of them are called channels and fountains to the letters (וְכֻלְּהוּ אִתְקְרִיאוּ צִנּוֹרִין וּמַבּוּעִין לְאַתְוָון), which are included in the earth, which is the lower Shekhinta (דְּאִינוּן כְּלִילָן בְּקַרְקַע, דְּאִיהִי שְׁכִינְתָּא תַּתָּאָה), which is called “garden” (דְּאִתְקְרִיאַת גַּ״ן). She is encompassed from the fifty-three orders of the Orayta (כְּלִילָא מִתְּלַת וְחַמְשִׁין סְדָרִין דְּאוֹרַיְיתָא). Of her it is said: “A locked garden is My sister, My bride, a locked fountain, a sealed spring” (וַעֲלָהּ אִתְּמַר גַּן נָעוּל אֲחוֹתִי כַלָּה, גַּל נָעוּל מַעְיָן חָתוּם) (Song of Songs 4). “Sealed” indeed, because She is a virgin and no man has known her (חָתוּם וַדַּאי, בְּגִין דְּאִיהִי בְּתוּלָה וְאִישׁ לֹא יְדָעָהּ). And She is the wisdom of Shlomo (וְאִיהִי חָכְמַת שְׁלֹמֹה). Of her it is said: “And the wisdom of Shlomo was multiplied” (דַעֲלָהּ אִתְּמַר וַתֵּרֶב חָכְמַת שְׁלֹמֹה) (I Kings 5). She was increased from every watering of every Sefirah (אִתְרַבִּיאַת מִכָּל שַׁקְיוּ דְכָל סְפִירָה וּסְפִירָה), by the hand of that channel which is Vav (עַל יְדָא דְהַהוּא צִנּוֹרָא דְאִיהוּ ו׳), until She reached that supernal fountain which is Yod, the supernal Chokhmah, the wisdom of all the children of the East (עַד דִּמְטִיאַת לְהַהוּא מַבּוּעָא עִלָּאָה דְאִיהִי יוֹ״ד עִלָּאָה חָכְמַת כָּל בְּנֵי קֶדֶם). And at that time She became a crown upon the head of the letter Vav (וּבְהַהוּא זִמְנָא אִתְעֲבִידַת אִיהִי תַּגָּא בְּרֵישָׁא דְאָת ו׳).
And come and see: the lower Shekhinta, when She is watered from the points, She is called Chirik, Cholem, Shuruk (וְתָא חֲזִי, שְׁכִינְתָּא תַּתָּאָה כַּד אִיהִי אִתְשַׁקְיָא מִן נְקוּדִין, אִתְקְרֵי חִירֵ״ק חֹלֵ״ם שׁוּרֵ״ק). For whom? For that channel which is Vav (לְמָאן לְהַהוּא צִנּוֹר דְאִיהוּ ו׳), in which are included six channels (דִּכְלִילָן שִׁית צִנּוֹרִין). All of them are from six letters, which are Alef, Bet, Gimel, Yod, Tav, Tzadi, etc. (דְּכֻלְּהוֹן מִשִּׁית אַתְוָון, דְּאִינוּן אבגית״ץ וְכוּ׳). Six channels are those that depend on him (שִׁית צִנּוֹרִין אִינוּן דְּתַלְיָין מִנֵּיהּ). And he includes six others (וְאִיהוּ כְּלִיל שִׁית אָחֳרָנִין). And all of them ascend to Mem-Bet (וְכֻלְּהוּ סָלְקִין לְמ״ב). She is called Chirik, Cholem, Shuruk of that channel (אִתְקְרִיאַת חִירֵ״ק חֹלֵ״ם שׁוּרֻ״ק דְּהַהוּא צִנּוֹר), in this likeness: וִֹ. And thus She is called in relation to Yod (וְהָכִי אִתְקְרִיאַת לְגַבֵּי יוֹ״ד). And thus in relation to Heh (וְהָכִי לְגַבֵּי ה׳). And the secret of the matter: “I am first, and I am last…” (וְרָזָא דְמִלָּה אֲנִי רִאשׁוֹן וַאֲנִי אַחֲרוֹן וְגוֹ׳) (Isaiah 44). And at times She is a crown upon the head of the letter Vav (וּלְזִמְנִין אִיהִי עֲטָרָה עַל רֵישָׁא דְאָת ו׳), in this likeness (כְּגַוְונָא דָא). And the secret of the matter: “He stretches out the heavens like a curtain” (וְרָזָא דְמִלָּה נוֹטֶה שָׁמַיִם כַּיְרִיעָה) (Isaiah 40). And this is the secret of the head of the letter Alef (וְדָא רָזָא דְרֵישָׁא דְאָת א׳). And at times She descends… (וּלְזִמְנִין נָחִית).
Notes
Namely Kamatz, Pataḥ, Tzere, Segol, Sheva, Ḥolam, Ḥirik, Kubutz, and Shuruk, which is called Melopum (כְּלוֹמַר קָמַץ פַּתַח צֵירֵי סֶגוֹל שְׁוָא חוֹלָם חִירִיק קֻבּוּץ וְשׁוּרוּק שֶׁהוּא נִקְרָא מְלוֹפּוּם).
