Light from darkness and chesed refined from din

לימי ר"ח וסוכות איתא ישת חושך סתרו זה ר"ה בכסה.

For the days of Rosh Chodesh and Sukkos it is taught: "He made darkness His hiding place" (Tehillim 18:12) — this is Rosh Hashanah, [as it says] "on the covered [day]" (Tehillim 81:4).

The Sefas Emes opens the Tishrei cycle by linking Rosh Hashanah, the "concealed" festival (ba'keseh), to the verse about Hashem making darkness His hidden dwelling.

כי אשב בחושך ה' אור לי.

"Though I sit in darkness, Hashem is a light for me" (Michah 7:8).

Even when a person is in spiritual darkness, Hashem Himself becomes the hidden light within that very darkness.

יודעי תרועה באור פניך יהלכון.

"Those who know the teruah-blast walk in the light of Your countenance" (Tehillim 89:16).

Those who grasp the inner meaning of the shofar's teruah on Rosh Hashanah merit to walk in Hashem's light — the light hidden within the day's concealment.

כי עיקר האור גנוז בחושך.

For the essential light is hidden within the darkness.

This is the governing principle: the deepest light is precisely that which is concealed within darkness.

כדאיתא ראיות האדם מתוך החשוך שבעינים.

As is found, a person's sight comes from the dark part of the eye.

Even physically, vision flows from the dark pupil — a parable for how light and perception emerge from darkness.

וז"ש ביצחק יקרא לך זרע ביצחק ולא כל יצחק.

And this is the meaning of "for through Yitzchak shall offspring be called yours" (Bereishis 21:12) — "through Yitzchak," but not all of Yitzchak.

Chazal read "b'Yitzchak" as "part of Yitzchak," meaning only the portion of Yitzchak that was refined and clarified — a hint to extracting light from within din.

והוא בכוונה מכוונת שיצא יעקב מתוך יצחק.

And this was by precise design, that Yaakov should emerge from within Yitzchak.

It was intentional that Yaakov, the aspect of rachamim, would be drawn out from within Yitzchak, the aspect of din.

וזרע אברהם נגנז ביצחק.

And the seed of Avraham was concealed within Yitzchak.

Avraham's chesed was hidden inside Yitzchak's din, waiting to be revealed.

ונתברר בו ויצא משם יעקב.

And it became clarified within him, and from there Yaakov emerged.

The hidden chesed was refined and extracted from within the din of Yitzchak, producing Yaakov.

והוא בחי' הרחמים.

And this is the aspect of rachamim (mercy).

Yaakov represents the middah of rachamim that emerges from within din.

החסד שנתברר בדין.

The chesed that was clarified within the din.

True rachamim is the chesed that has been refined and brought forth out of strict judgment.

וז"ש ראשית חכמה יראת ה' מכלל שסופו אהבה ורחמים.

And this is the meaning of "the beginning of wisdom is yiras Hashem" (Tehillim 111:10) — which implies that its end is love and mercy.

Yirah is only the beginning; the verse's wording shows that fear is meant to give way to ahavah and rachamim — light emerging from the awe.

כדאיתא תחלתו קשה וסופו רך.

As is found, "its beginning is hard and its end is soft."

The avodah begins with the harshness of yirah but resolves into the softness of love and mercy.

וכן הוא בחודש הזה.

And so it is in this month.

The month of Tishrei follows this very pattern — beginning with awe and ending in joy.

שכל תכלית חג הסוכות יצא מכח אל הפועל באמצעיות ימים הנוראים.

For the entire purpose of Chag HaSukkos is brought from potential into actuality through the medium of the Yamim Nora'im.

The joy of Sukkos does not stand alone; it is the fruit that the awe of the Yamim Nora'im brings into being — the "soft" end emerging from the "hard" beginning.

וכ' מן המיצר קראתי יה ענני במרחב יה.

And it is written, "From the straits I called upon Y-ah; He answered me with the expanse of Y-ah" (Tehillim 118:5).

The verse pairs the "narrowness" of the cry with the "expanse" of the answer — both bearing the Name Y-ah — mapping the Tishrei journey.

וזה השם הוא בחי' ר"ה ויוכ"פ וסוכות.

And this Name corresponds to Rosh Hashanah, Yom Kippur, and Sukkos.

The Name Y-ah, appearing in both the strait and the expanse, encompasses the whole arc of the Yamim Nora'im through Sukkos.

ומקודם הי' נסתר במיצר.

And beforehand it was concealed within the straits.

On Rosh Hashanah and Yom Kippur the Name is hidden within the "narrowness" of awe and judgment.

ובסוכות הוא במרחב.

And on Sukkos it is in the expanse.

By Sukkos the same Name is revealed in the "broad space" of joy and closeness.

והם ב' מיני תפלות.

And these are two kinds of tefillah.

The straits and the expanse correspond to two distinct modes of prayer.

תפלה לעני.

"A prayer of the poor man" (Tehillim 102:1).

One mode is the cry of the destitute from within the straits — the tefillah of Rosh Hashanah and Yom Kippur.

תפלה למשה.

"A prayer of Moshe" (Tehillim 90:1).

The other is the elevated prayer of Moshe — the avodah of the expanse, of Sukkos.

כ' שלום לרחוק ולקרוב.

It is written, "Peace, peace, to the far and to the near" (Yeshayahu 57:19).

Hashem extends shalom both to the one who is "far" and the one who is "near" — to both modes of return.

ובר"ה כתיב מרחוק ה' נראה.

And regarding Rosh Hashanah it is written, "From afar Hashem appeared to me" (Yirmiyahu 31:2).

Rosh Hashanah is the avodah of "from afar" — reaching toward Hashem from a place of distance.

כי הקב"ה ידו פשוטה לקבל שבים בבחי' רחוק וקרוב.

For the Holy One's hand is outstretched to receive those who do teshuvah, in the aspect of both far and near.

Hashem accepts the baal teshuvah whether he comes from afar or from up close — His hand is extended to all.

ולכן כל אדם צריך לשוב בעשי"ת ובסוכות.

Therefore every person must do teshuvah during the Aseres Yemei Teshuvah and on Sukkos.

There are two seasons of return — the awe-filled Ten Days, and the joyous days of Sukkos.

ויש מתקרבין מתוך המיצר ויש מתוך השמחה.

And some draw close through the straits, and some through joy.

People reach Hashem by different paths — some through the pressure of distress, others through the warmth of simchah.

ומי שאינו שב בב' אלו עליו נאמר ורגז ושחק ואין נחת.

And one who does not return through either of these, about him it is said, "and he rages and laughs, and there is no rest" (Mishlei 29:9).

Whoever is moved neither by the awe nor by the joy remains restless — neither the "raging" of awe nor the "laughter" of simchah brings him to teshuvah.

וכ' טובה תוכחת מגולה זה בר"ה.

And it is written, "Better is open rebuke" (Mishlei 27:5) — this is on Rosh Hashanah.

Rosh Hashanah's awe is the "open rebuke" — a direct, revealed call to teshuvah.

ובסוכות מאהבה מסותרת.

And on Sukkos, "[better is open rebuke] than hidden love" (Mishlei 27:5).

Sukkos works through "hidden love" — a gentler, concealed drawing-close born of ahavah.

כדכ' אשר יאהב ה' יוכיח.

As it is written, "for whom Hashem loves He rebukes" (Mishlei 3:12).

The "open rebuke" of the Yamim Nora'im is itself an expression of Hashem's love, like a father correcting a beloved son.

ואח"כ כאב את בן ירצה הוא בסוכות.

And afterward, "like a father who favors a son" (Mishlei 3:12) — this is on Sukkos.

After the rebuke comes the loving favor of a father pleased with his son — the warmth and ratzon of Sukkos.

ובחודש זה נתברר מדת יצחק ביצחק ולא כל יצחק.

And in this month the middah of Yitzchak was clarified — "through Yitzchak, but not all of Yitzchak."

Tishrei, the month of Yitzchak's din, is when the chesed hidden within din is refined — only the clarified part of "Yitzchak" is drawn forth.

דכ' בבארות שחפר יצחק רבו פלשתים ואמרו לנו המים.

As it is written regarding the wells that Yitzchak dug, the Pelishtim quarreled and said, "the water is ours" (Bereishis 26:20).

The Pelishtim could lay claim to Yitzchak's wells, since the "water" of yirah has an external aspect that even they can grasp.

ובבארות אברהם כתיב סתמום פלשתים.

And regarding the wells of Avraham it is written, "the Pelishtim stopped them up" (Bereishis 26:18).

Avraham's wells of ahavah, by contrast, the Pelishtim could only block, not claim — love has no foothold for the sitra achra.

כי אהבה מיוחד רק לבנ"י ואין שייכות לסט"א.

For ahavah belongs exclusively to Bnei Yisrael, and the sitra achra (the "other side") has no connection to it.

The middah of love is uniquely Yisrael's; the forces of impurity can have no share in it whatsoever.

אבל ביראה יש יראה חיצוניות וזה לנו המים.

But within yirah there is an external yirah, and this is "the water is ours."

Fear has an outer layer — fear of punishment — which even the Pelishtim can claim, hence "the water is ours."

כי יראת עונש נמצא בכל הברואים.

For fear of punishment is found in all creatures.

Yiras ha'onesh, dread of consequences, is a universal instinct shared by all created beings.

ובנ"י צריכין לברר יראה אמיתית מכח רוממות אל בלבד.

And Bnei Yisrael must clarify a true yirah, born solely from the power of the exaltedness of Hashem.

Klal Yisrael's task is to refine fear into yiras ha'romemus — awe rooted purely in Hashem's greatness, not in self-interest.

והיא יראת ה' לחיים:

And this is "the yiras Hashem that leads to life" (Mishlei 19:23).

This refined, exalted yirah is the one that brings genuine life — the chesed and rachamim drawn out from within the din.

Summary: The avodah of Tishrei follows the pattern of light hidden within darkness and chesed clarified from within din — just as Yaakov (rachamim) emerged from Yitzchak. The Yamim Nora'im are the "straits" and "open rebuke" where the Name is concealed; Sukkos is the "expanse" and "hidden love" where it is revealed, the joy that the awe brings into being. One may return to Hashem through either distress or joy, but must refine fear of punishment into true yiras ha'romemus — the awe born of Hashem's exaltedness, which is the yiras Hashem that leads to life.
