Shavuos and the unified fiftieth gate

בליל יום טוב זה יורד טהרה לבנ"י כמ"ש בזוה"ק לנטרא דכיא דמטי עלי' בליליא דא.

On the night of this Yom Tov, taharah (purity) descends upon Bnei Yisrael, as the Zohar HaKadosh states: "to guard the pure one upon whom it comes on this night."

The night of Shavuos brings a special downpour of purity onto Bnei Yisrael, readying them for kabbalas haTorah.

כי הקב"ה מטהר בנ"י שהם יהיו כלים טהורים לקבל התורה כמ"ש אמרות ה' כו' טהורות כו' אתה ה' תשמרם כו' ע"ש ובמדרש אמור פרשנו תשמרם לאמרות באמצעיות טהרת לבות בנ"י ממילא התורה שבהם נשמרת ג"כ.

For the Holy One, blessed be He, purifies Bnei Yisrael so that they will be pure vessels to receive the Torah, as it says, "The sayings of Hashem are pure sayings... You, Hashem, will guard them..." (Tehillim 12:7-8), see there. And in the Midrash on Emor we explained "You will guard them" as referring to the "sayings": through the purification of the hearts of Bnei Yisrael, the Torah within them is automatically guarded as well.

Hashem purifies the people themselves so their hearts become clean vessels; once the hearts that hold the Torah are pure, the Torah deposited within them is preserved along with them.

והכנה זו הי' כל ימי הספירה.

This preparation took place throughout all the days of Sefiras HaOmer.

The forty-nine days of Sefirah are the avodah of preparing and purifying these vessels for the Torah.

אכן בימי הספירה הוא לברר הפרשת מ"ט פנים טהור בין מ"ט פנים טמא.

However, the days of Sefirah are for the clarification of separating the forty-nine "pure faces" from the forty-nine "impure faces."

During Sefirah the work is one of birur (sifting) — distinguishing the forty-nine facets of purity from the forty-nine facets of impurity, step by step.

אמנם בשבועות הוא שער הנ' ושם הכל טהור.

But on Shavuos it is the fiftieth gate, and there everything is pure.

Shavuos reaches the shaar hanun (fiftieth gate), a level above the sifting, where there is no impurity at all — all is pure.

כי לא יש רק מ"ט פנים טמא וטהור.

For there are only forty-nine "faces" of impure and pure.

The division into pure and impure exists only within the forty-nine; impurity reaches no higher than the forty-ninth level.

והיינו המשכת כח שיש בפנים טמא ג"כ כי פנים הוא הפנימיות.

This means the drawing forth of the [holy] power that exists even within the "impure face," for "panim" denotes the penimiyus (inner dimension).

Even the "impure facet" contains a hidden inner force, since "panim" really points to an inner point; the fiftieth gate draws out and redeems that buried holiness.

אבל קודם התפשטותן למ"ט פנים שם הכל אחדות אחד.

But prior to their spreading out into the forty-nine "faces," there everything is a single unity.

At the root, before reality branches into forty-nine facets, all is one undivided oneness — and that root is the level of Shavuos.

לכן בעצרת אית בי' ביטול יצה"ר ולכן שתי הלחם מחמץ להראות כי בשורש הכל אחדות אחד וטהור.

Therefore on Atzeres (Shavuos) there is a nullification of the yetzer hara, and that is why the Shtei HaLechem (Two Loaves) are brought from chametz — to show that at the root everything is a single, pure unity.

Because Shavuos reaches the unified root above all division, the yetzer hara is nullified there. The Two Loaves are deliberately leavened — chametz, which usually symbolizes the yetzer hara — to demonstrate that even what seems impure is, at its source, part of the one pure oneness.

לכן נק' יום הבכורים שבשורש יש תמיד התחדשות ולא יוכל להתיישן כלל זה היום:

Therefore it is called "Yom HaBikkurim" (the Day of First Fruits), for at the root there is always renewal, and this day can never grow old at all.

"Bikkurim" connotes firstness and freshness. Because Shavuos draws from the unified root where everything is perpetually new, the day itself never becomes stale — it carries within it constant hischadshus (renewal).

Summary: On the night of Shavuos, Hashem pours down purity to make Bnei Yisrael into clean vessels for the Torah. The days of Sefirah are a gradual sifting between forty-nine facets of purity and impurity, but Shavuos rises to the fiftieth gate — the unified root above all division, where even the "impure" reveals its hidden inner holiness and all is one. Hence the yetzer hara is nullified, the Two Loaves are brought from chametz to show the root is wholly pure, and the day is "Yom HaBikkurim," ever-new and never growing old.
