Two scrolls with letters of the Aleph-Bet emanating from above to below. The first piece flows from Aleph to Yud, the second from Khaf to Taf.  
 
Tanya, Part II: Sha’ar HaYichud VehaEmunah, Chapter 1:

“…If the letters of the Ten Utterances by which the earth was created during the Six Days of Creation were to depart from it [but] for an instant, G–d forbid, it would revert to naught and absolute nothingness, exactly as before the Six Days of Creation.”

אִילּוּ הָיוּ מִסְתַּלְּקוֹת מִמֶּנָּה כְּרֶגַע חַס וְשָׁלוֹם הָאוֹתִיּוֹת מֵעֲשָׂרָה מַאֲמָרוֹת שֶׁבָּהֶן נִבְרֵאת הָאָרֶץ בְּשֵׁשֶׁת יְמֵי בְרֵאשִׁית, הָיְתָה חוֹזֶרֶת לְאַיִן וָאֶפֶס מַמָּשׁ, כְּמוֹ לִפְנֵי שֵׁשֶׁת יְמֵי בְרֵאשִׁית מַמָּשׁ.

“This same thought was expressed by the Arizal when he said that even in completely inanimate matter, such as stones or earth or water, there is a soul and spiritual life-force—that is, the enclothing of the “Letters of speech” of the Ten Utterances which give life and existence to inanimate matter that it might arise out of the naught and nothingness which preceded the Six Days of Creation.”

וְזֶהוּ שֶׁאָמַר הָאֲרִ״י זִכְרוֹנוֹ לִבְרָכָה, שֶׁגַּם בְּדוֹמֵם מַמָּשׁ, כְּמוֹ אֲבָנִים וְעָפָר וּמַיִם, יֵשׁ בְּחִינַת נֶפֶשׁ וְחַיּוּת רוּחָנִית. דְּהַיְינוּ, בְּחִינַת הִתְלַבְּשׁוּת אוֹתִיּוֹת הַדִּבּוּר מֵעֲשָׂרָה מַאֲמָרוֹת הַמְחַיּוֹת וּמְהַוּוֹת אֶת הַדּוֹמֵם, לִהְיוֹת יֵשׁ מֵאַיִן וָאֶפֶס שֶׁלִּפְנֵי שֵׁשֶׁת יְמֵי בְרֵאשִׁית.

“Now, although the name ‘even’ (stone) is not mentioned in the Ten Utterances recorded in the Torah, nevertheless, life-force flows to the stone through combinations and substitutions of the letters which are transposed in the “two hundred and thirty-one gates,” either in direct or reverse order, as is explained in the Sefer Yetzirah, until the combination of the name even descends from the Ten Utterances, and is derived from them, and this is the life-force of the stone.“

‎וְאַף שֶׁלֹּא הוּזְכַּר שֵׁם ״אֶבֶן״ בַּעֲשָׂרָה מַאֲמָרוֹת שֶׁבַּתּוֹרָה, אַף־עַל־פִּי־כֵן, נִמְשָׁךְ חַיּוּת לָאֶבֶן עַל יְדֵי צֵירוּפִים וְחִילּוּפֵי אוֹתִיּוֹת, הַמִּתְגַּלְגְּלוֹת בְּרל״א שְׁעָרִים פָּנִים וְאָחוֹר, כְּמוֹ שֶׁכָּתוּב בְּסֵפֶר יְצִירָה, עַד שֶׁמִּשְׁתַּלְשֵׁל מֵעֲשָׂרָה מַאֲמָרוֹת וְנִמְשָׁךְ מֵהֶן צֵירוּף שֵׁם ״אֶבֶן״, וְהוּא חַיּוּתוֹ שֶׁל הָאֶבֶן.
