The Alter Rebbe opens this letter with a deeply personal address: אהוביי, אחיי, ורעיי, אשר כנפשי—my beloved, my brothers, and my friends, who are like my own soul. He is speaking here from the heart, expressing a profound love and connection to the Chabad brotherhood he is addressing.

He emphasizes that he feels for them as he does for himself. This is not just a formal greeting; it sets the tone for the entire letter, which is written in a spirit of closeness and genuine concern for their spiritual well-being.

The Alter Rebbe continues, saying that he has come באתי כמזכיר, ומעורר ישנים בתרדמת הבלי הבלים—I have come as a reminder, to awaken those who are sleeping in the deep slumber of vanities of vanities.

He is describing a spiritual sleep, where people become absorbed in the trivialities and distractions of the world. The Alter Rebbe is urging his listeners to wake up from this state, to shake off the spiritual lethargy that comes from being caught up in meaningless pursuits.

This is a call to become aware, to realize that there is more to life than just the day-to-day concerns and material matters. He wants to rouse them from their complacency, to remind them of their true purpose and higher calling.

The Alter Rebbe then says his goal is ולפקוח עיני העורים, יביטו לראות—to open the eyes of the blind, so that they may look and truly see.

This is a metaphor for spiritual blindness. He wants people to recognize what really matters, to see beyond the surface and perceive the deeper reality of life. It's not enough to go through the motions; one must open their eyes to the truth and meaning behind their actions.

He is encouraging everyone to look honestly at themselves and their lives, to see where their focus is and to redirect their vision toward what is truly important.

The Alter Rebbe explains what he wants them to see: להיות כל ישעם וחפצם ומגמתם, לכל בהם חיי רוחם, במקור מים חיים, חיי החיים, כל ימי חייהם, מנפש ועד בשר—that all of their yearnings, desires, and goals should be to include within them the spirit of their life, in the source of living waters, the life of life, all the days of their lives, from soul to flesh.

He is saying that everything a person wants or strives for should be infused with spiritual purpose. Not just the obviously holy things, but even their desires and ambitions in this world should be connected to the source of true life—Hashem, who is called חיי החיים—the life of life.

This means that from the most spiritual part of a person, their soul, down to their physical existence, everything should be directed toward and included in a higher, G‑dly purpose. The Alter Rebbe is urging them to make their entire lives, in every aspect, a channel for holiness and connection to Hashem.

He clarifies further: דהיינו, כל מילי דעלמא ועסקי פרנסה, לא יהיה כאלו דעבדין לגרמייהו—that is, all worldly matters and all occupations, even earning a livelihood, should not be done like those who act for themselves, for their own sake.

The Alter Rebbe is teaching that even when we are involved in mundane activities—business, work, providing for our families—we should not approach these things with a selfish mindset, as if our only goal is personal gain or comfort.

Instead, he is calling for a shift in perspective: everything we do, even the most material pursuits, should be for a higher purpose, not just for ourselves. This is a fundamental difference between a Jew's approach to life and that of someone who is only focused on their own needs.

The Alter Rebbe warns that ולא יהיה בית ישראל כעובדי עבודת גילולים, דזנין ומפרנסין ומוקרין לנשייהו ובנייהו מאהבה—the house of Israel should not be like those who serve idolatry, who feed, support, and honor their wives and children out of love, meaning out of a purely physical or natural love.

He points out that among the nations, people care for their families simply because of natural affection. But for a Jew, this cannot be the sole motivation. Our love and care for our families must be rooted in something deeper than just physical or emotional attachment.

The Alter Rebbe is emphasizing that our actions, even towards those closest to us, should be guided by Torah and a sense of divine purpose, not just by instinct or self-interest.

He brings a verse to highlight the uniqueness of the Jewish people: כי: "מי כעמך ישראל גוי אחד בארץ" כתיב—for it is written, "Who is like Your nation Israel, one nation on earth."

This means that even when Jews are involved in earthly matters, they remain a goy echod—a singular, unified nation, connected to Hashem's oneness. The Alter Rebbe is stressing that our identity and purpose are not lost even in the midst of worldly affairs.

Being a Jew means that everything we do, even in the most physical aspects of life, is permeated with the awareness of Hashem's unity. We are not like other nations, whose involvement in the world is disconnected from the divine.

The Alter Rebbe explains further: דהיינו, שגם בעניני ארץ, לא יפרידו [נ"א יפרדו] מאחד האמת ח"ו—that is, even in matters of the earth, they should not separate themselves, G‑d forbid, from the one truth.

He is teaching that even when we are engaged in the most mundane, physical activities, we must not allow ourselves to become disconnected from echod ha'emez—the true oneness, which is Hashem.

This is a warning not to compartmentalize our lives, as if there is a time for G‑d and a time for everything else. Rather, the unity of Hashem must permeate all aspects of our existence, so that we never, even for a moment, lose sight of our connection to the one truth.

The Alter Rebbe warns us not to, G‑d forbid, להעיד עדות שקר—bear false witness, when we recite Krias Shema in the evening and in the morning. He points out that we say ה' אחד—Hashem is One, with our eyes closed, as the Shulchan Aruch instructs, to help us concentrate and not be distracted by the world around us.

But what does it mean to declare ה' אחד—Hashem is One? The teacher explains that the word "Echad" is made up of an Alef, Ches, and Dalet. The Alef stands for the One G‑d, the Ches represents the seven heavens and the earth, and the Dalet stands for the four directions of the world. In other words, we are testifying that Hashem is the only true existence, everywhere and in everything.

The Alter Rebbe is emphasizing that when we say ה' אחד, we are making a powerful statement: that there is nothing else besides Hashem, not just in the spiritual realms, but in every aspect of the physical world as well. We must be careful not to contradict this truth by the way we live our lives after saying Shema.

The Alter Rebbe continues by referencing the idea of בפקוח עיני העורים—opening the eyes of the blind. He brings a verse from Mishlei: התעיף עיניך בו, ואיננו—you blink your eyes at it, and suddenly it is gone, G‑d forbid.

The teacher explains that this is a warning: sometimes a person can be so inspired during Shema, closing his eyes and declaring Hashem's oneness, but as soon as he opens his eyes and returns to daily life, that awareness disappears. It's as if the inspiration is lost in a moment—the person forgets what he just proclaimed.

This is a call to remain conscious of Hashem's unity not only during moments of prayer, but also when we "open our eyes" and engage with the world. We shouldn't be like those who are spiritually blind, who forget Hashem as soon as they leave the moment of davening.

The Alter Rebbe now tells us what is truly fitting for us: אך בזאת יאות לנו—this is what is appropriate for us. What is it? That all of our involvement in worldly matters, כל עסקינו במילי דעלמא, should not be לא לגרמייהו—not for our own selfish purposes.

The teacher explains that even when we are busy with the things of this world—our work, our business, our daily needs—we shouldn't approach them with a self-centered attitude. Our focus should not be on "what's in it for me," but rather on a higher purpose.

This is a central message of the letter: that a Jew's engagement with the world is not meant to be for personal gain or materialism alone. Instead, everything we do should be infused with a sense of mission and connection to Hashem.

So, if not for ourselves, what is the purpose? The Alter Rebbe says: כי אם להחיות נפשות חלקי אלקות—rather, it is to give life to souls, which are parts of G‑dliness. Our involvement in the world is meant to support and sustain the G‑dly souls around us.

He continues: ולמלאות מחסוריהם בחסד חנם—to fill their needs with pure kindness, kindness that is given freely, without expecting anything in return.

The teacher elaborates that this means when we provide for others, whether it's our family or anyone else, our motivation should be to nurture the G‑dly spark within them. We give not because of what we get back, but because we are fulfilling a higher purpose—doing kindness for its own sake, as Hashem does.

The Alter Rebbe explains that by acting this way, שבזה אנו מדמין הצורה ליוצרה—we are imitating the form to its Creator. In other words, we are emulating Hashem, who is ה' אחד—the One G‑d.

He quotes the verse, חסד אל כל היום—the kindness of G‑d is all day. Hashem's kindness is constant and true, חסד של אמת—a kindness of truth. Hashem sustains the entire world and everything in it, every single moment, להחיות העולם ומלואו בכל רגע ורגע—to give life to the world and all its fullness at every instant.

The teacher points out that when we act with selfless kindness, we are reflecting Hashem's own way of giving. Our goal is to bring that same divine energy into our lives and the lives of those around us, sustaining others as Hashem sustains us.

However, the Alter Rebbe clarifies that רק שאשתו ובניו של אדם קודמין לכל על פי התורה—a person's wife and children come first, according to the Torah.

The teacher explains that while we are meant to care for all G‑dly souls, the Torah instructs us that our immediate family takes precedence. This is not because of personal preference or selfish love, but because Hashem, through the Torah, has established this order.

So, when we provide for our family, we are fulfilling Hashem's will, prioritizing those whom the Torah says should come first. But even this should be done with the awareness that we are nurturing the G‑dly soul within them, not just acting out of natural affection or self-interest.
