(ב) שֹׁרֶשׁ הַמִּצְוָה יָדוּעַ, שֶׁהוּא כְּדֵי לְלַמֵּד נַפְשֵׁנוּ לֶאֱהֹב הַטּוֹב וְהַתּוֹעֶלֶת וּלְהִדָּבֵק בּוֹ, וּמִתּוֹךְ כָּךְ תִּדְבַּק בָּנוּ הַטּוֹבָה, וְנַרְחִיק מִכָּל דָּבָר רַע וּמִכָּל דְּבַר הַשְׁחָתָה. וְזֶהוּ דֶּרֶךְ הַחֲסִידִים וְאַנְשֵׁי מַעֲשֶׂה, אוֹהֲבִים שָׁלוֹם וּשְׂמֵחִים בְּטוּב הַבְּרִיּוֹת וּמְקָרְבִים אוֹתָן לַתּוֹרָה, וְלֹא יְאַבְּדוּ אֲפִלּוּ גַּרְגֵּר שֶׁל חַרְדָּל בָּעוֹלָם, וְיֵצַר עֲלֵיהֶם בְּכָל אֲבַדּוֹן וְהַשְׁחָתָה שֶׁיִּרְאוּ, וְאִם יוּכְלוּ לְהַצִּיל יַצִּילוּ כָּל דָּבָר מֵהַשְׁחִית בְּכָל כֹּחָם. וְלֹא כֵן הָרְשָׁעִים אֲחֵיהֶם שֶׁל מַזִּיקִים, שְׂמֵחִים בְּהַשְׁחָתַת עוֹלָם, וְהֵמָּה מַשְׁחִיתִים אֶת עַצְמָם, בְּמִדָּה שֶׁאָדָם מוֹדֵד בָּהּ מוֹדְדִין לוֹ. כְּלוֹמַר, בָּהּ הוּא נִדְבָּק לְעוֹלָם, וּכְעִנְיָן שֶׁכָּתוּב (משלי יז, ה) שָׂמֵחַ לְאֵיד לֹא יִנָּקֶה. וְהֶחָפֵץ בַּטּוֹב וְשָׂמֵחַ בּוֹ נַפְשׁוֹ בְּטוֹב תָּלִין לְעוֹלָם, זֶה יָדוּעַ וּמְפֻרְסָם.
(2) The root of this commandment is well-known — it is in order to teach our souls to love good and benefit and to cling to it. And through this, good clings to us and we will distance [ourselves] from all bad and destructive things. And this is the way of the pious and people of [proper] action — they love peace and are happy for the good of the creatures and bring them close to Torah, and they do not destroy even a grain of mustard in the world. And they are distressed by all loss and destruction that they see; and if they can prevent it, they will prevent any destruction with all of their strength. But not so are the wicked — the brothers of the destructive spirits. They rejoice in the destruction of the world, and they destroy themselves — [since] in the way that a person measures, so is he measured; which is to say that he clings to it forever, as the matter that is written (Proverbs 17:5), “the one who rejoices in calamity, will not be cleared (of evil).” And the one who desires the good and rejoices in it, “his soul will dwell in the good” forever. This is known and famous.
