Holy dispute and unity through bittul

איתא במשנה כל מחלוקת שאינה לש"ש אין סופה להתקיים זו מחלוקת קרח וכל עדתו.

It is taught in the Mishnah (Avos 5:17): "Every dispute (machlokes) that is not for the sake of Heaven (l'shem Shomayim) will not endure in the end — this is the dispute of Korach and all his company."

The Sefas Emes opens from the Mishnah's classic example of a dispute that was not for Heaven's sake and therefore could not last: that of Korach.

כי מחלוקת היא מדה קשה ובא מצד מדה"ד ולכן כל שאינה לשם שמים ממש אינה מתקיים.

For machlokes is a harsh quality and comes from the side of middas hadin (the attribute of strict justice); therefore any dispute that is not literally for the sake of Heaven does not endure.

Because conflict draws from the severe attribute of judgment, only a dispute genuinely for Heaven's sake has the merit to survive.

הגם דגבי תורה ומצות אמרו מתוך שלא לשמה בא לשמה.

Even though regarding Torah and mitzvos they said, "From doing it not for its own sake (shelo lishmah) one comes to do it for its own sake (lishmah)."

The Sefas Emes anticipates an objection: with Torah and mitzvos we tolerate impure motives, since they lead to pure ones.

אבל מחלוקת צריך להיות רק לשם שמים.

But machlokes must be only for the sake of Heaven.

Dispute is different: it can be justified solely when it is purely for Heaven's sake, with no allowance for lesser motives.

ובאמת גם בכנסי' אמרו כשאינה לשם שמים אין סופה להתקיים זה מטעם אחר כי עוה"ז עלמא דפרודא כולו קטטה לכן עוה"ז מתנגד להאחדות ולכן כל שאינה לש"ש א"י להתקיים בעוה"ז.

And in truth, even regarding a gathering (kenisah / assembly) they said that when it is not for the sake of Heaven it will not endure — but this is for a different reason: because this world is "the world of separation" (alma deperuda), entirely strife; therefore this world opposes unity, and so anything not for the sake of Heaven cannot endure in this world.

The Mishnah's parallel statement about an assembly works oppositely: since olam hazeh is by nature a realm of fragmentation and friction, it resists true unity, so a gathering lacking l'shem Shomayim has no power to last here.

והנה באמת צריך האדם להשתמש בב' הבחי' מחלוקת וכנסי' והוא בחי' סור מרע להלחם עם הסט"א.

Now in truth a person must make use of both aspects — machlokes and kenisah (dispute and gathering): this corresponds to "turn away from evil" (sur mei'ra), to wage war against the sitra achra (the side of impurity).

Both modes have a holy use; "dispute" is the energy of waging war against evil, the "turn from evil" half of avodah.

ועשה טוב הוא בחי' התקשרות באחדות.

And "do good" (asei tov) is the aspect of binding oneself in unity.

"Gathering" is the positive half — "do good" — the work of joining together in achdus.

וב' אלו בחי' ימי המעשה והשבת.

And these two correspond to the weekdays and Shabbos.

The combative "turn from evil" belongs to the striving of the weekdays; the unifying "do good" belongs to Shabbos.

וגם זה אמת כפי המחלוקת בימי המעשה כך זוכין אח"כ אל השבת כמ"ש והב בסופה אהבה בסופה.

And this too is true: according to the "dispute" (the struggle against evil) during the weekdays, so does one afterward merit Shabbos — as it says, "Vahev in its end" (Bamidbar 21:14), read as "love (ahavah) in its end."

The battle waged against evil through the week is precisely what earns the love and unity of Shabbos at its close — strife rightly used culminates in love.

והנה בקרח הי' שני הבחי' דכתיב ויקח הוא המחלוקת וכתיב ויקהל עליהם קרח.

Now in Korach both aspects were present: it is written, "And Korach took (vayikach)" — this is the machlokes; and it is written, "and Korach assembled (vayakhel) against them" (Bamidbar 16:19) — this is the gathering.

Korach embodied both modes: "taking" (the divisive dispute) and "assembling" (the false gathering of his congregation).

ושניהם לא הי' לש"ש ולא נתקיימו ועל ב' אלו אמר בסודם אל תבוא נפשי בקהלם אל תחד כו'.

And both of them were not for the sake of Heaven and did not endure; and concerning these two Yaakov said, "Into their counsel let my soul not come; in their assembly let not my honor be united" (Bereishis 49:6).

Since neither Korach's dispute nor his assembly was l'shem Shomayim, both collapsed — and Yaakov had already disavowed both his "counsel" (the dispute) and his "assembly" (the gathering).

כי הנה יעקב דכתיב בי' אמת ליעקב.

For behold, regarding Yaakov it is written, "truth to Yaakov" (titen emes l'Yaakov, Michah 7:20).

Yaakov is the bearer of the attribute of emes (truth), which is why he is the one to repudiate Korach's falsehood.

אמת כולל ב' הבחי'.

"Truth" includes both aspects.

True emes encompasses both the combative and the unifying modes in their proper, holy form.

בחי' אאע"ה הי' לקרב הכל.

The aspect of Avraham Avinu, peace upon him, was to draw everyone near.

Avraham represents the unifying mode — bringing all people close, the chesed of "do good."

ובחי' יצחק המחלוקת כמ"ש ויריבו רועי גרר כו'.

And the aspect of Yitzchak is the machlokes, as it says, "and the herdsmen of Gerar quarreled" (Bereishis 26:20).

Yitzchak, the attribute of din, represents the holy "dispute" mode — the struggle reflected in the contention over his wells.

ויעקב כולל שניהם.

And Yaakov includes both of them.

Yaakov, who is emes, integrates the chesed of Avraham and the din of Yitzchak — both modes in balance.

וכמו כן מרע"ה שר התורה.

And likewise Moshe Rabbeinu, the master of the Torah.

Moshe, as the channel of the whole Torah, similarly contains both modes.

והתורה יש בה בחי' מ"ע ומל"ת ואם הי' קרח מבטל עצמו למרע"ה הי' לו עלי' ותיקון:

And the Torah contains the aspect of mitzvos asei (positive commandments) and mitzvos lo sa'aseh (negative commandments); and had Korach nullified himself (bittul) to Moshe Rabbeinu, he would have had an elevation and a tikkun.

The Torah itself unites "do" and "do not" — the two modes — through Moshe; had Korach submitted to Moshe in bittul, his very combative energy could have been elevated and rectified instead of destroying him.

Summary: Machlokes stems from the harsh attribute of din, so unlike Torah study it is legitimate only when purely l'shem Shomayim; and any assembly lacking that purity cannot endure in this "world of separation." Yet both "dispute" and "gathering" have a holy purpose — "turn from evil" and "do good," the weekdays and Shabbos — and the battle against evil earns the love of unity. Korach corrupted both, "taking" and "assembling" not for Heaven's sake, and so both collapsed, as Yaakov (emes, who unites the chesed of Avraham and din of Yitzchak) had foretold. Had Korach instead nullified himself to Moshe and the Torah, which itself joins the positive and negative commandments, his energy would have been elevated and rectified.
