Sukkos joy and the inner eighth day

כתיב לב יודע מרת נפשו.

It is written: "The heart knows the bitterness of its soul."

The Sefas Emes takes this verse as a doorway to explaining the role of Bnei Yisrael as the "heart" of the world.

שבנ"י נקראו לב שהמה פנימיות החיות שבעולם.

For Bnei Yisrael are called "the heart," for they are the penimiyus (inner core) of the life-force in the world.

Just as the heart is the inner vital center of the body, Bnei Yisrael are the inner point of vitality within all of creation.

ולכן המה מרי נפש בר"ה ויוהכ"פ דכתיב ועניתם את נפשותיכם.

Therefore they are "bitter of soul" on Rosh Hashanah and Yom HaKippurim, as it is written, "and you shall afflict your souls."

Because they are the sensitive "heart" of the world, Bnei Yisrael feel the bitterness of the Days of Awe, fulfilling the mitzvah of affliction on Yom Kippur.

וזוכין אח"כ בסוכות לשמחה כמ"ש ובשמחתו לא יתערב זר.

And afterward, on Sukkos, they merit joy, as it is written, "and in its joy no stranger shall mingle."

The affliction of the Yamim Nora'im gives way to the simchah of Sukkos — a joy so intimate that no outsider can share in it.

וזהו הגנת הסוכה שלא יהי' שייכות להם בשמחתן של ישראל.

And this is the protection of the Sukkah: that they (the outside forces) should have no share in the joy of Yisrael.

The Sukkah's sheltering walls represent a spiritual barrier that keeps foreign forces from attaching themselves to the unique joy of Bnei Yisrael.

לכן נותנים להם חלקם בע' פרים כידוע.

Therefore they are given their portion in the seventy bulls, as is known.

The seventy bulls offered over Sukkos correspond to the seventy nations; this is the "portion" allotted to them, keeping them separate from Yisrael's own inner joy.

והעיקר מתקיים בשמ"ע דדרשו חז"ל והיית אך שמח על יו"ט האחרון.

And the essence is fulfilled on Shemini Atzeres, for Chazal expounded "and you shall be only joyful" as referring to the final Yom Tov.

The truest, undiluted joy is reserved for Shemini Atzeres, the final festival day — "only joyful," with nothing mixed in.

שאז אין להם שום חלק כמ"ש עצרת תהי' לכם.

For then they (the nations) have no share at all, as it is written, "it shall be an atzeres for you."

On Shemini Atzeres only one bull is offered; the nations have no portion whatsoever — "for you" means for Bnei Yisrael alone.

כי ז' ימי הסוכות הם קיום הטבע שמתפשט החיים היורד בתחלת השנה לקיום העולם.

For the seven days of Sukkos are the sustaining of nature, in which the life-force that descends at the start of the year spreads out to sustain the world.

The seven days of Sukkos correspond to the natural order through which the year's new vitality, drawn down at Rosh Hashanah, expands to maintain all of creation.

ושמיני עצרת הוא בחי' הנשמה יתירה אור ז' הימים ושם אין שום מגע נכרי כלל.

And Shemini Atzeres is the aspect of the neshamah yeseirah, the light of the seven days, and there is no foreign contact there at all.

Shemini Atzeres stands above the natural seven days like an "added soul," gathering up their light into a purely inner dimension that nothing external can touch.

ופרשנו פסוק שמח זבולון בצאתך הוא על שמחת ז' ימי הסוכות.

And we explained the verse "Rejoice, Zevulun, in your going out" as referring to the joy of the seven days of Sukkos.

Zevulun, the tribe of outward enterprise, corresponds to the joy of the seven days, which is bound up with the outer, natural world.

ונקרא יציאה שהיא שמחת כלל הבריאה כנ"ל.

It is called "going out" because it is the joy of all of creation, as above.

The seven days' joy is a "going out" into the world, shared by the whole of creation that is sustained by the descending vitality.

לכן יש לכולם חלק.

Therefore all have a share in it.

Since this joy belongs to the sustaining of all creation, even the nations have their portion in it.

ולכן צריך סוכה והגנה שלא יתערבו בשמחתן של ישראל.

Therefore a Sukkah and protection are needed, so that they not mingle in the joy of Yisrael.

Precisely because the seven days' joy is universal, Bnei Yisrael need the Sukkah's protection to guard their own deeper joy from being intermixed with it.

ויששכר באוהליך הוא שמ"ע ושמחת תורה שהיא עיקר האהל של בנ"י.

"And Yissachar, in your tents" — this is Shemini Atzeres and Simchas Torah, which is the essential tent of Bnei Yisrael.

Yissachar, the tribe of Torah study "in tents," corresponds to Shemini Atzeres and Simchas Torah — the inner sanctuary of Bnei Yisrael.

ולכן אז אין צריך הגנה ששם אין שום מגע נכרי.

Therefore then no protection is needed, for there is no foreign contact there.

By Shemini Atzeres the joy is so wholly internal that it requires no protective Sukkah — nothing foreign can reach it.

וצריכין לבטל כל הימים ליום השמיני.

And one must subordinate all the days to the eighth day.

The avodah is to direct and nullify all seven days, with their outward joy, toward the higher purpose of the eighth — bittul of the natural toward the supernal.

ולכן עושין שמחת תורה להודיע כי כל השמחה בחיים ושפע פרנסה.

Therefore we make Simchas Torah, to make known that all the joy of life and the abundance of parnasah (sustenance)…

Simchas Torah declares the true purpose of all life's joy and material plenty.

כדי שנוכל לעסוק בתורה מתוך הרחבה.

…is so that we can engage in Torah amid abundance.

All material blessing is ultimately given so that a person can immerse in Torah with a settled, expansive mind.

כמו שעשה זבולון שותפות עם יששכר:

Just as Zevulun made a partnership with Yissachar.

The classic Yissachar-Zevulun partnership embodies this: Zevulun's worldly enterprise exists to support Yissachar's Torah — the outer serving the inner.

Summary: Bnei Yisrael are the "heart" and inner vitality of the world, who feel the bitterness of the Yamim Nora'im and then attain joy on Sukkos. The seven days of Sukkos correspond to the natural order that sustains all creation — a universal joy in which even the nations share, which is why the protective Sukkah is needed to guard Yisrael's own joy. Shemini Atzeres and Simchas Torah are the purely inner "tent" of Bnei Yisrael, untouched by anything foreign, to which all the days are subordinated — teaching, like the Yissachar-Zevulun partnership, that all worldly joy and abundance exist only to enable the study of Torah amid tranquility.
