Shabbos consciousness in every act

אך את שבתותי תשמורו כו' אות הוא ביני וביניכם כו' לדעת כי אני ה' מקדישכם.

"Only you shall guard My Shabbosos… it is a sign between Me and you… to know that I am Hashem who sanctifies you."

The Sefas Emes opens with the pasuk in which Shabbos is called an "os" (sign) between Hashem and Bnei Yisrael, a sign through which we come to know that Hashem sanctifies us.

פי' שבכל דבר צריכין לשמור בחי' השבת.

The meaning is that in everything one must guard the aspect (bechinah) of Shabbos.

The "Shabbos consciousness" is not limited to the seventh day; it must be preserved within every activity.

פשוט הנייחא שיש להקב"ה מכל הבריאה שלכבודו ברא בכלל ובפרט לזכור לעשות כל המעשים כדי לגמור רצונו ית' מה שהוא אף שא"י כראוי איך.

Simply: the "rest" (naycha) that the Holy One, blessed be He, has from all of creation — which He created for His honor, in general and in particular — is to remember to do all one's actions in order to fulfill His will (ratzon Hashem), whatever it is, even though one does not properly know how.

The "satisfaction" Hashem takes in creation is realized when a person does everything with the intent of carrying out Hashem's will, even when he cannot fully grasp how — for the whole world was created to give Him honor.

וזה תכלית הבריאה.

And this is the purpose of creation.

Living with this intent — doing everything for the sake of Hashem's will — is the very goal for which the world was made.

וז"ש שבתותי.

And this is the meaning of "My Shabbosos."

The plural "My Shabbosos" hints at this ongoing Shabbos-awareness carried into every act, not only the day itself.

כי אות הוא כו' פי' זאת היא דביקות בנ"י בהקב"ה כדאיתא אורייתא וישראל וקוב"ה כולהו חד.

"For it is a sign…" — meaning, this is the attachment (deveikus) of Bnei Yisrael to the Holy One, blessed be He, as it is brought: "the Torah, Yisrael, and the Holy One, blessed be He, are all one."

Shabbos being a "sign" expresses the deveikus of Bnei Yisrael with Hashem, reflecting the Zohar's teaching that Torah, Yisrael, and Hashem are bound together as one.

פי' שבנ"י דבוקים בעיקר החיות.

Meaning that Bnei Yisrael are attached to the very root of the life-force (ikar hachiyus).

Bnei Yisrael are connected to the inner source of all vitality, Hashem Himself.

נמצא כפי מה שמעלין כל דבר לשורשו ומתדבקין בפנימיות החיות של הקב"ה.

It emerges that according to how one raises every thing up to its root and cleaves to the inner life-force (penimiyus hachiyus) of the Holy One, blessed be He.

By elevating each thing back to its source and attaching to the inner Divine vitality within it.

כמו כן מתעורר כח בנ"י ג"כ.

So correspondingly the power of Bnei Yisrael is also aroused.

This act of elevation awakens and strengthens the spiritual power of Bnei Yisrael themselves.

וזהו לדעת כי אני ה' מקדישכם.

And this is "to know that I am Hashem who sanctifies you."

Recognizing that all vitality flows from Hashem is precisely the "knowing" that He is the One who sanctifies us.

לכן כל שמתעורר כח הקב"ה מתעורר ג"כ כח בנ"י.

Therefore, whenever the power of the Holy One, blessed be He, is aroused, the power of Bnei Yisrael is also aroused.

Because of this bond, awakening the Divine vitality in the world simultaneously awakens the inner strength of Bnei Yisrael.

וכתב רש"י לרבות שגם במלאכת המשכן ישמרו השבת.

And Rashi writes [that the word "ach" comes] to include that even during the work of the Mishkan they should keep Shabbos.

Rashi explains that the verse teaches that even the sacred labor of building the Mishkan does not override Shabbos.

הרמז שאף במעשה של מצוה צריכין לזכור עיקר המכוון לעשות רצונו ית' בלבד.

The hint is that even in the performance of a mitzvah one must remember the essential intent — to do His will alone.

Even while engaged in a mitzvah as great as the Mishkan, the core intent must remain solely fulfilling ratzon Hashem.

שלא להתערב טובת עצמו לגמרי.

So as not to mix in any of his own self-interest at all.

No trace of personal benefit or ego should taint the deed.

רק לשם שמים.

Only for the sake of Heaven (l'shem Shomayim).

The act must be purely for Hashem's sake.

והוא שבח שמחזיר המעשה לעושהו כנ"ל:

And this is the praise of "returning the deed to its Maker," as above.

Acting purely for Hashem returns the deed to its true Source — the highest avodah, the very "rest" that creation gives Hashem.

Summary: Shabbos is called an "os," a sign of the deveikus binding Bnei Yisrael to Hashem, in keeping with the teaching that Torah, Yisrael, and Hashem are one. The "Shabbos consciousness" must be carried into every action — doing all one's deeds purely to fulfill ratzon Hashem, with no self-interest. By raising each thing to its root and cleaving to the inner Divine vitality, one awakens both Hashem's power in the world and the inner strength of Bnei Yisrael, coming "to know that Hashem sanctifies us." Even the holy work of the Mishkan yields to Shabbos, teaching that every mitzvah must be done solely l'shem Shomayim, "returning the deed to its Maker."
