Shofar reconnects creation to its pristine root

במדרש לעולם ה' דברך נצב בשמים כו'.

In the Midrash: "Forever, Hashem, Your word stands firm in the heavens etc." (Tehillim 119:89)

The Sefas Emes opens with the pasuk teaching that Hashem's creative "word" stands eternally in the heavens — the spiritual root that continually sustains all things.

כי לכל הדברים יש שורש למעלה וכפי התדבקות הכל בשורש נמשך חיות חדש.

For all things have a root above, and in accordance with how everything cleaves to its root, a renewed life-force is drawn down.

Every created thing has a spiritual source on high. The more a thing clings to that root, the more fresh chiyus (life-force) flows into it.

וזהו בחי' תקיעת שופר כי בשורש יש התפארות לכל הדברים כמ"ש וירא אלקים כו' כל אשר עשה כו' טוב מאוד כו'.

And this is the aspect of the blowing of the shofar; for at the root there is glory (hispaarus) to all things, as it is written: "And God saw etc. all that He had made etc. and behold it was very good etc." (Bereishis 1:31)

Blowing the shofar reconnects all things to their root, where everything is seen in its original glory — as at the close of creation, when Hashem saw all He had made and it was "very good." The shofar awakens that primal vision of perfection.

והנה בחג השבועות הוא בחי' עץ החיים.

Now, the festival of Shavuos is the aspect of the Tree of Life (Eitz HaChaim).

Shavuos, the time of receiving the Torah, corresponds to the Eitz HaChaim — pure life above the realm of judgment.

אמנם ר"ה בחי' תיקון עץ הדעת טו"ר והוא בחי' המשפט והדין.

But Rosh Hashanah is the aspect of the repair of the Tree of Knowledge of good and evil, and it is the aspect of judgment and din.

Rosh Hashanah, by contrast, corresponds to repairing the Eitz HaDaas of good and evil — the realm of mixture — and is therefore the time of mishpat and din, sorting good from evil.

ולכן תשרי מאזנים שיש שם ב' הבחי' ימין ושמאל.

Therefore Tishrei is "the Scales" (Libra), for there both aspects are present — right and left.

The zodiacal sign of Tishrei is the Scales, fittingly, because this month holds both aspects in balance — the "right" of chesed and the "left" of din — weighing good against evil.

ותקיעות שופר לעורר התדבקות הראשון שהי' קודם החטא כמ"ש בגמ' משור פר משופר כו'.

And the blowing of the shofar is to awaken the original attachment that existed before the sin, as stated in the Gemara: "from 'shor' (ox), 'par' (bull), 'shofar' etc."

The shofar awakens the original bond to the root that existed before Adam's sin — before good and evil became intertwined. The Gemara's wordplay on shor, par, shofar hints at this return to the pristine state.

ולכן כתב בזוה"ק כי מי ששומר ספירת העומר וחג השבועות כראוי א"צ לבוא במשפט בר"ה ע"ש בפ' תצוה.

Therefore the Zohar HaKadosh writes that whoever properly observes Sefiras HaOmer and the festival of Shavuos need not come into judgment on Rosh Hashanah — see there in Parshas Tetzaveh.

Because Shavuos belongs to the Eitz HaChaim, beyond judgment, one who keeps the Omer count and Shavuos properly attaches himself to that realm of pure life and is thereby spared the din of Rosh Hashanah.

כתבנו בספר החיים היא החיים הברור בלי תערובות:

We have written that "the Book of Life" is the life that is clear, without admixture.

To be inscribed in the "Book of Life" means to attain the clarified life of the Eitz HaChaim — life entirely free of the mixture of good and evil that characterizes the Eitz HaDaas.

Summary: All things draw renewed life by clinging to their root above, where everything stands in its original glory; the shofar awakens this bond as it was before the sin. Shavuos corresponds to the Eitz HaChaim — pure life beyond judgment — while Rosh Hashanah is the repair of the Eitz HaDaas, the realm of din. One who properly observes the Omer and Shavuos attaches to that pure, unmixed life and is inscribed in the Book of Life, sparing him the judgment of Rosh Hashanah.
