Now, though “G-d is one and His Name is one,”39

וְהִנֵּה, אַף כִּי "ה' אֶחָד וּשְׁמוֹ אֶחָד",

i.e., [though] His speech and the “breath of His mouth,” which in the sacred Zohar40 is referred to as His Name, is singularly and uniquely one,

דְּהַיְינוּ, דִּבּוּרוֹ וְ"רוּחַ פִּיו" הַמְכוּנֶּה בַּזּוֹהַר הַקָּדוֹשׁ בְּשֵׁם "שְׁמוֹ" – הוּא יָחִיד וּמְיוּחָד,

nevertheless, the radiance and efflux of life-force which issues forth from His mouth divides into four different levels. These are the Four Worlds—Atzilut, Beriah, Yetzirah, and Asiyah.41

אַף־עַל־פִּי־כֵן, הַהֶאָרָה וְהַמְשָׁכַת הַחַיּוּת הַנִּמְשֶׁכֶת מֵ"רוּחַ פִּיו" יִתְבָּרֵךְ, מִתְחַלֶּקֶת לְד' מַדְרֵגוֹת שׁוֹנוֹת, שֶׁהֵן ד' עוֹלָמוֹת: אֲצִילוּת, בְּרִיאָה, יְצִירָה, עֲשִׂיָּה.

The difference is due to (42many) contractions and screens

וְהַשִּׁינּוּי הוּא מֵחֲמַת צִמְצוּמִים וּמָסָכִים (רַבִּים),

that veil and obscure the light and the life-force so that it will not radiate in the World of Beriah as much as in the World of Atzilut;

לְצַמְצֵם הָאוֹר וְהַחַיּוּת, וּלְהַסְתִּירוֹ, שֶׁלֹּא יְהֵא מֵאִיר כָּל כָּךְ בְּעוֹלַם הַבְּרִיאָה כְּמוֹ בְּעוֹלַם הָאֲצִילוּת,

and in the World of Yetzirah, [the opaqueness is thickened] by means of further contractions and screens, and so on, i.e., how much more so in the World of Asiyah.

וּבְעוֹלַם הַיְצִירָה הוּא עַל יְדֵי צִמְצוּמִים וּמָסָכִים יוֹתֵר וְכוּ'.

Nevertheless, there is no change whatsoever, heaven forfend, in the essence of the Shechinah, which is the “word of G-d” and the “breath of His mouth.”

אֲבָל אֵין שׁוּם שִׁינּוּי חַס וְשָׁלוֹם בְּעַצְמוּת הַשְּׁכִינָה, שֶׁהִיא "דְבַר ה'" וְ"רוּחַ פִּיו".

Also, as regards the radiance and efflux of life-force that issues from the “word of G-d,”

וְגַם בִּבְחִינַת הַהֶאָרָה וְהַמְשָׁכַת הַחַיּוּת,

the radiance which is in [the World of] Atzilut pierces the screen and vests itself in [the World of] Beriah. Likewise from [the World of] Beriah to [the World of] Yetzirah and from [the World of] Yetzirah to [the World of] Asiyah.

הִנֵּה הַהֶאָרָה שֶׁבַּאֲצִילוּת – בּוֹקַעַת הַמָּסָךְ וּמִתְלַבֶּשֶׁת בַּבְּרִיאָה, וְכֵן מִבְּרִיאָה לִיצִירָה וּמִיצִירָה לַעֲשִׂיָּה,

Hence, the [infinite] Ein Sof-light which is in [the World of] Atzilut is also present in [the World of] Asiyah, and [even] in this material world,

וְלָכֵן, אוֹר־אֵין־סוֹף בָּרוּךְ־הוּא שֶׁבַּאֲצִילוּת, הוּא גַּם כֵּן בַּעֲשִׂיָּה וּבָעוֹלָם הַזֶּה הַחוּמְרִי,

by being invested in the [sefirah of] malchut of [the Worlds of] Beriah, Yetzirah, and Asiyah, as fully explained in the writings of Rabbi Yitzchak Luria, of blessed memory.43

עַל־יְדֵי הִתְלַבְּשׁוּתוֹ בְּמַלְכוּת דִּבְרִיאָה־יְצִירָה־עֲשִׂיָּה, כִּמְבוֹאָר הַכֹּל בְּכִתְבֵי הָאֲרִ"י זִכְרוֹנוֹ לִבְרָכָה:
