Part IV; Iggeret HaKodesh, Chapter 23
The whole chapterאבִּגְזֵירַת עִירִין פִּתְגָמָא וּמַאֲמַר קַדִּישִׁין, חַכְמֵי הַמִּשְׁנָה עֲלֵיהֶם־הַשָּׁלוֹם, שֶׁשָּׁנוּ בְּמִשְׁנָתָם: ״עֲשָׂרָה שֶׁיּוֹשְׁבִין וְעוֹסְקִין בַּתּוֹרָה שְׁכִינָה שְׁרוּיָה בֵינֵיהֶם״, ״כִּי זֶה כָּל הָאָדָם״. וְאַף גַּם זֹאת הָיְתָה כָּל יְרִידָתוֹ בָּעוֹלָם הַזֶּה לְצוֹרֶךְ עֲלִיָּה זוֹ, אֲשֶׁר אֵין עֲלִיָּה לְמַעְלָה הֵימֶנָּה.
1TWENTY-THREE. “The matter is by the decree of the watch-angels and the say of the holy ones”1—the Sages of the Mishnah, may peace be on them, who taught in their Mishnah: “Ten that sit and busy themselves with Torah, the Shechinah dwells among them.”2 This is the whole of man.3 Moreover, (man’s) very descent to this world was for the purpose of this ascent, of which there is none higher.
בכִּי שְׁכִינַת עוּזּוֹ אֲשֶׁר בְּגָבְהֵי מְרוֹמִים, וְ״הַשָּׁמַיִם וּשְׁמֵי הַשָּׁמַיִם לֹא יְכַלְכְּלוּ״ אֵימָתָהּ – תִּשְׁכּוֹן וְתִתְגַּדֵּל בְּתוֹךְ בְּנֵי יִשְׂרָאֵל, כְּמוֹ שֶׁכָּתוּב: ״כִּי אֲנִי ה׳ שׁוֹכֵן בְּתוֹךְ בְּנֵי יִשְׂרָאֵל״, עַל־יְדֵי עֵסֶק הַתּוֹרָה וְהַמִּצְוֹת בַּעֲשָׂרָה דַוְקָא, כְּמוֹ שֶׁאָמְרוּ רַבּוֹתֵינוּ־זִכְרוֹנָם־לִבְרָכָה: ״אַתְיָא תּוֹךְ תּוֹךְ כוּ׳״. וְעַל זֶה נֶאֱמַר: ״בְּקִרְבְּךָ קָדוֹשׁ״, וְ״אֵין דָּבָר שֶׁבִּקְּדוּשָּׁה בְּפָחוֹת מֵעֲשָׂרָה״.
2For the Indwelling of His Might (Shechinat Uzo), which is in the heights of the upper realms4 and whose awesomeness the heavens and the heavens of the heavens cannot contain,5 dwells and becomes magnified among the children of Israel. Thus it is written: “For I, the L–rd, dwell among (toch) the children of Israel”6—through the occupation with Torah and the commandments by ten, expressly, as our Sages, of blessed memory, said: “We compare toch-toch…”;7 of this it was said: “The Holy One in your midst,”8 and “There is no matter of holiness with less than ten.”9
גוּמִשּׁוּם הָכֵי נַמֵי, אִצְטְרִיךְ לְהוּ לְרַבּוֹתֵינוּ־זִכְרוֹנָם־לִבְרָכָה לְמֵילַף מִקְּרָא: ״מִנַּיִן שֶׁאֲפִילוּ אֶחָד שֶׁיּוֹשֵׁב וְעוֹסֵק בַּתּוֹרָה כוּ׳״. וְאַף גַּם זֹאת, לֹא מָצְאוּ לוֹ סְמַךְ מִן הַמִּקְרָא אֶלָּא לִקְבִיעַת שָׂכָר בִּלְבַד, לְיָחִיד לְפִי עֶרְכּוֹ לְפִי [נוסח אחר: וּלְפִי] עֵרֶךְ הַמְרוּבִּים, אֲבָל לְעִנְיַן הַשְׁרָאַת קְדוּשַּׁת הַקָּדוֹשׁ־בָּרוּךְ־הוּא – אֵין לוֹ עֵרֶךְ אֲלֵיהֶם כְּלָל.
3Therefore, too, our Sages, of blessed memory, need to derive from Scripture whence we know that even one who sits occupied with Torah….10 And even so they did not find from Scripture support for that, but only for the allotment of a reward to the individual, proportionate to himself and in proportion11 to the many.12 But as to causing an indwelling (hashraah) of G–d’s Holiness, (the individual) cannot be compared to (the multitude) at all.
