What the sources say

The most direct language of breaking down appears in Mesillat Yesharim 1:28, which states that a person must "break down all the barriers" (לִשְׁבֹּר כָּל הַמְּחִצּוֹת) that separate him from his Creator — barriers the text identifies specifically as all matters of physicality and what depends on them — until he is drawn toward G-d like iron to a magnet; begin here for the clearest formulation of this obligation.

Building on that same imperative, the Tanya (Likkutei Amarim 30:6) frames it as an actual fierce battle, requiring each person to weigh whether he is waging war against his body and animal soul with sufficient force — using the language of beating and grinding them "like dust" — which maps precisely onto the inner work of dismantling one's middos that Mesillat Yesharim describes as breaking down barriers.

Mesillat Yesharim 1

מסילת ישרים א׳ — ד"ה וְאָמְנָם רָאוּי לוֹ שֶׁתִּהְיֶה כָּל פְּנִיָּתוֹ

Mesillat Yesharim 1:28

Ramchal opens by stressing that human beings must examine and refine their path in life, beginning with self-scrutiny and correction of character. While not using the same Chassidic language of 'breaking' middos, it is a foundational mussar source for dismantling bad habits and traits.

וְאָמְנָם רָאוּי לוֹ שֶׁתִּהְיֶה כָּל פְּנִיָּתוֹ רַק לַבּוֹרֵא יִתְבָּרַךְ, וְשֶׁלֹּא יִהְיֶה לוֹ שׁוּם תַּכְלִית אַחֵר בְּכָל מַעֲשֶׂה שֶׁיַּעֲשֶׂה אִם קָטָן וְאִם גָּדוֹל אֶלָּא לְהִתְקָרֵב אֵלָיו יִתְבָּרַךְ וְלִשְׁבֹּר כָּל הַמְּחִצּוֹת הַמַּפְסִיקוֹת בֵּינוֹ לְבֵין קוֹנוֹ, הֵן הֵנָּה כָּל עִנְיְנֵי הַחָמְרִיּוּת וְהַתָּלוּי בָּהֶם, עַד שֶׁיִּמָּשֵׁךְ אַחֲרָיו יִתְבָּרַךְ מַמָּשׁ כַּבַּרְזֶל אַחַר אֶבֶן הַשּׁוֹאֶבֶת.

Thus it is proper that all of a man's inclination be solely to the blessed Creator and that all of his actions great or small have no other purpose than to draw closer to G-d, blessed be He, and to break down all the barriers separating him from his Master, which are all the matters of physicality and the things dependent on them, until he is drawn towards the blessed G-d like iron is drawn to a magnet.

Tanya 30

תניא, חלק ראשון; ליקוטי אמרים ל׳ — ד"ה וְהִנֵּה

Tanya, Part I; Likkutei Amarim 30:6

The Alter Rebbe describes how a person should break and crush the yetzer hara and the arrogance that feeds it, emphasizing a posture of humility and self-nullification in avodah. This is one of the clearest classical Chassidic sources using the language of breaking oneself to refine character traits.

וְהִנֵּה, בֶּאֱמֶת, שֶׁהִיא מִלְחָמָה גְדוֹלָה וַעֲצוּמָה, לִשְׁבּוֹר הַיֵּצֶר הַבּוֹעֵר כְּאֵשׁ לֶהָבָה מִפְּנֵי פַּחַד ה׳, וּכְמוֹ נִסָּיוֹן מַמָּשׁ. וְהִלְכָךְ, צָרִיךְ כָּל אָדָם, לְפִי מַה שֶּׁהוּא מְקוֹמוֹ וּמַדְרֵגָתוֹ בַּעֲבוֹדַת ה׳, לִשְׁקוֹל וְלִבְחוֹן בְּעַצְמוֹ אִם הוּא עוֹבֵד ה׳ בְּעֵרֶךְ וּבְחִינַת מִלְחָמָה עֲצוּמָה כָּזוֹ וְנִסָּיוֹן כָּזֶה, בִּבְחִינַת ״וַעֲשֵׂה טוֹב״. כְּגוֹן, בַּעֲבוֹדַת הַתְּפִלָּה בְּכַוָּונָה, לִשְׁפּוֹךְ נַפְשׁוֹ לִפְנֵי ה׳ בְּכָל כֹּחוֹ מַמָּשׁ עַד מִיצּוּי הַנֶּפֶשׁ, וּלְהִלָּחֵם עִם גּוּפוֹ וְנֶפֶשׁ הַבַּהֲמִית שֶׁבּוֹ הַמּוֹנְעִים הַכַּוָּונָה – בְּמִלְחָמָה עֲצוּמָה, וּלְבַטְּשָׁם וּלְכַתְּתָם כֶּעָפָר קוֹדֶם הַתְּפִלָּה שַׁחֲרִית וְעַרְבִית מִדֵּי יוֹם בְּיוֹם, וְגַם בִּשְׁעַת הַתְּפִלָּה, לְיַיגֵּעַ עַצְמוֹ בִּיגִיעַת נֶפֶשׁ וִיגִיעַת בָּשָׂר, כְּמוֹ שֶׁיִּתְבָּאֵר לְקַמָּן בַּאֲרִיכוּת.

It is indeed a great and fierce struggle to break one’s passion, which burns like a fiery flame, through fear of G–d; it is like an actual test. Therefore, each person according to his place and rank in the service of G–d must weigh and examine his position as to whether he is serving G–d in a manner commensurate with the dimensions of such a fierce battle and test—in the realm of “do good,” as, for example, in the service of prayer with kavanah (devotion), pouring out his soul before G–d with his entire strength, to the point of exhaustion of the soul, while waging war against his body and animal soul within it which impede his devotion, a strenuous war to beat and grind them like dust, each day before the morning and evening prayers. Also during prayer he needs to exert himself, with the exertion of the spirit and of the flesh, as will be explained later at length.
