Kosher signs as keys to inner holiness

והנה בענין זאת החי' אשר תאכלו.

Now, regarding the matter of "This is the living thing (chayah) which you may eat" (Vayikra 11:2).

The Sefas Emes opens on the laws of kosher animals, reading "chayah" not only as "animal" but with overtones of "chiyus" (life-force) — the inner vitality that determines what may be eaten.

כי חיות התורה נמצא בכל מקום כמ"ש כולם בחכמה עשית.

For the life-force of the Torah (chiyus ha'Torah) is found in every place, as it is written, "You made them all with wisdom (kulam b'chochmah asisa)" (Tehillim 104:24).

The Divine vitality that flows from the Torah is present everywhere in creation, since everything was made with Hashem's wisdom. In principle, a holy spark of chiyus lies hidden within every created thing.

אבל יש דברים שא"י להוציא החיות מחמת התערובות טו"ר.

But there are things from which one cannot extract the life-force (chiyus), because of the admixture (ta'aroves) of tov va'ra (good and evil).

Yet not every spark is accessible. In some things the holy chiyus is so entangled with evil — a mixture of good and bad — that it cannot be drawn out and elevated. These are the forbidden, non-kosher creatures.

וזה הסימן מעלת גרה ומפרסת פרסה.

And this is (the meaning of) the sign of "chewing the cud (ma'alas gerah)" and "having split hooves (mafreses parsah)."

The two kosher signs — chewing the cud and split hooves — are not arbitrary markers but symbols indicating whether a creature's inner chiyus can be redeemed.

כי יש בכל דבר ב' מפתחות. פנימית וחיצונית.

For in every thing there are two "keys" (maftechos) — an inner one (penimis) and an outer one (chitzonis).

Accessing the holy spark within anything requires unlocking two layers: an outer "key" that breaks through the surface, and an inner "key" that reaches the hidden core.

וצריכין מקודם לפתוח הסגר הטבע והגשמיות שלא יהי' מגושם ביותר.

And one must first open the "lock" of nature and physicality (ha'sger ha'teva v'ha'gashmiyus), so that it not be overly coarse/material.

The first step is the outer key: breaking open the hard shell of physicality, so the material does not remain sealed in coarse, opaque matter that blocks any access to its inner light.

וזה הסימן שוסעת שסע שלא נסגר לגמרי ויש סדק ושער לבטל הקליפה וההסתר.

And this is the sign of "wholly cleft (shosa'as shesa)" — that it is not entirely closed, but there is a crack and an opening (sa'ar) to nullify the kelipah (husk) and the concealment (hester).

The split hoof symbolizes the outer key: a creature whose "shell" is not completely sealed shut, but has a fissure — an opening through which the surrounding husk of concealment can be broken and the hidden light reached.

ואח"כ צריכין לפתוח נקודה הקדושה פנימית.

And afterward one must open the inner holy point (nekudah ha'kedoshah penimis).

Once the outer shell is breached, the second, inner key is needed: to draw forth the holy point of chiyus concealed at the very core.

וזה הסימן מעלה גרה שהרמז שיכולין להעלות הפנימיות.

And this is the sign of "chewing the cud (ma'alah gerah)" — the hint being that one is able to "raise up" (le'ha'alos) the penimiyus (inner essence).

Chewing the cud (ma'alah gerah, literally "bringing up") symbolizes the inner key: a creature whose inner holiness can be drawn up and elevated. The word itself hints at raising up the penimiyus.

ונמשכת אחר איש ישראל האוכלו בקדושה.

And it is drawn after the Jew who eats it in holiness (bi'kedushah).

When a kosher creature's inner spark can be elevated, it becomes "drawn after" the Jew who eats it with holy intent — its chiyus is uplifted and absorbed into avodas Hashem.

והמינים האסורים אין בכח להעלות הקדושה מהם.

And the forbidden species (ha'minim ha'asurim) — it is not within (one's) power to raise up the holiness from them.

The non-kosher creatures lack one or both signs, meaning their holy spark is locked behind a shell or core that cannot be opened. Their chiyus cannot be elevated, so eating them would not raise holiness but would entangle a person in the unredeemable mixture of good and evil.

לכן הבדילנו הקב"ה מהם כנ"ל:

Therefore the Holy One, blessed is He, separated us (hivdilanu) from them, as above.

For this reason Hashem set Bnei Yisrael apart from the forbidden species: since their holiness cannot be redeemed, eating them brings no elevation, and the Torah's separation guards the Jew's ability to draw holiness only from what can truly be uplifted.

Summary: The life-force of the Torah is hidden within all of creation ("You made them all with wisdom"), but in some things the holy chiyus is too entangled with evil to be extracted. The two kosher signs symbolize the two "keys" needed to release that inner spark: the split hoof (an opening in the shell) is the outer key that breaks through coarse physicality and nullifies the surrounding kelipah, and chewing the cud (ma'alah gerah, "bringing up") is the inner key that allows the holy inner point to be raised up. A creature with both signs can have its chiyus elevated by a Jew who eats it in holiness, while the forbidden species, lacking these signs, hold holiness that cannot be redeemed — which is why Hashem separated Bnei Yisrael from them.
