Why Do We Not Recite a Blessing over the Mitzvah of Affliction on Yom Kippur?

Why Do We Not Recite a Blessing over the Mitzvah of Affliction on Yom Kippur?

On the loftiest day of the year, when the soul removes the garments of materiality and wraps itself in the white of angels, the commandment “You shall afflict your souls” stands at the center of the entire day. A deep silence fills the synagogues, Jews everywhere stand in prayer, fasting and restraining the body in order to fulfill the Creator’s will. Yet a great question shakes the world of halakhah: if before every mitzvah, light or severe, we recite “Who has sanctified us with His commandments and commanded us,” why does this holy day, on which we fulfill a Torah commandment of affliction, pass without a mitzvah blessing? How can such an exalted act of sanctification and abstention, in which bodily vitality is diminished for the sake of the soul, have no verbal frame of praise and gratitude before its fulfillment? Is something lacking in the nature of the commandment, or is there a deeper secret in the silence that accompanies the fast from beginning to end?

We turn to the Torah’s formulation of the day. “In the seventh month, on the tenth of the month, you shall afflict your souls, and you shall do no work, the native and the stranger who dwells among you” (Leviticus 16:29). The Torah establishes two foundations: affliction and cessation from labor. The question is whether “you shall afflict” is a positive act upon which one should bless, or whether it defines a state of abstention that does not lend itself to a blessing.

Rashi (Leviticus 16:29) explains that affliction means refraining from eating and drinking. He compares the prohibition of labor and the affliction in that both are fulfilled in a mode of “sit and do not act.” Since the mitzvah is realized through what the person does not do, there is no obvious positive act upon which to apply the formula “and commanded us.” The classic mitzvah blessing normally sanctifies an active deed.

Rabbi Abraham ibn Ezra (Leviticus 16:29) explains that the affliction is a fast that leads to submission and regret. The word “your souls” refers to the desiring faculty within man, which must be restrained so the intellect can be refined. The affliction is therefore an inner process lasting many hours, not one sharply defined act. Perhaps for this reason there is no blessing, for a blessing ordinarily attaches to a definite beginning of a mitzvah, whereas the fast is a spiritual state extending across the day.

Ramban (Leviticus 16:29) explains that the mitzvah of affliction belongs to God’s kindness in granting Israel a day of atonement. The purpose of the fast is to resemble the angels, who have no eating and drinking. This opens another explanation: perhaps one does not bless because the mitzvah comes in the context of sin and atonement. A formal celebratory blessing is less appropriate when a person stands ashamed over his sins and seeks mercy through bodily restraint.

Sforno (Leviticus 23:27) explains that “you shall afflict your souls” is intended to lead a person to examine his ways and return to God. The affliction is therefore a means toward repentance, not the final end in itself. Since it is an instrument preparing the heart for teshuvah, one may understand why no separate blessing was instituted, just as one does not ordinarily bless over preparatory acts rather than over the mitzvah itself.

Kli Yakar (Leviticus 16:31) explains “a Sabbath of Sabbaths” as rest for body and soul. Affliction on Yom Kippur stands opposite the delight of Shabbat. Just as we do not recite “Who commanded us to delight in Shabbat” despite the positive dimension of Shabbat delight, so too there is no blessing over affliction, because experiences entrusted to body and soul, without one defined technical act, were not given a fixed blessing.

The Talmudic principles deepen the distinction between active performance and passive abstention.

Berakhot 9a discusses the rule that mitzvah blessings are recited “before their performance.” The blessing precedes the act and sanctifies it. This immediately creates a problem regarding affliction. What is the moment “before the performance” of a fast that lasts an entire day? Is it at the onset of the fast, or at every moment the person refrains from eating? The absence of a concrete moment of action makes the institution of a blessing difficult.

Pesahim 7b distinguishes, in the broader laws of mitzvah blessings, between commandments performed through positive action and obligations fulfilled through refraining from a prohibited act. We do not recite “Who commanded us not to eat non-kosher food” or “not to wear shaatnez.” Tosafot and later commentators use this principle to explain that although Yom Kippur affliction is formulated as a positive commandment, its practical fulfillment is through abstention, and blessings were not generally instituted over abstention.

The Jerusalem Talmud, Berakhot 6:1, discusses blessings over benefit and blessings over mitzvot. Blessings ordinarily attach to a tangible act or benefit. Yom Kippur affliction is the opposite of bodily benefit and the opposite of active performance. There is no concrete mitzvah-object to hold and act upon. The day’s holiness is expressed precisely through withdrawal from material reality.

Menahot 42b discusses the obligation of one hundred blessings and how to complete them on Yom Kippur when meal blessings are absent. One may supplement through fragrances or by answering to Torah blessings. This itself illustrates that no special blessing over the fast was instituted; had such a blessing existed, it would have naturally entered the count instead of requiring other supplements.

Yoma 73b discusses the five forms of affliction derived from “you shall afflict your souls.” Rashi and Tosafot describe them as forms of withdrawal and nullification. In yeshivah language, a mitzvah blessing normally accompanies the creation of a visible halakhic act or state through human action, whereas the sanctity of affliction comes through refraining. One does not bless over “non-action” in the same way one blesses over a constructive act.

Among the Rishonim, this distinction receives a more systematic formulation.

Rambam, Hilkhot Berakhot 5:1, establishes that mitzvah blessings were instituted around actions a person performs to fulfill his obligation. The mitzvot themselves include both active and non-active forms, but the classic blessing is attached to a recognizable act of fulfillment. Accordingly, commands fulfilled by abstaining from labor or food do not have the same blessing structure as lulav, tzitzit, or similar active acts.

Rashba, Responsa, part 1 no. 18, develops another principle concerning commandments associated with repairing a transgression or restoring a damaged state. Examples discussed by the Rishonim include returning stolen property, repayment, or disposal of prohibited remnants. A blessing of “Who sanctified us” is not always appropriate where the act itself recalls a prior sin or deficiency. On this basis later authorities explain that Yom Kippur affliction, whose entire context is atonement and cleansing from sin, is not naturally accompanied by a celebratory mitzvah blessing.

Semag, positive commandment 32, counts affliction as an explicit Torah positive commandment. Yet it differs from other mitzvot because it extends continuously throughout the full day. Later commentators infer that it is difficult to define a single moment of completion. At every instant of refraining from food, the mitzvah is renewed, and one blessing cannot easily be identified with an endless series of moments of abstention.

Rabbeinu Yonah, Shaarei Teshuvah, gate 4 section 17, describes affliction as part of the overall process of repentance, including submission and breaking the body’s dominance. Repentance is fundamentally a duty of the heart, and no blessing was fixed for the internal work of the heart. The fast is the outer expression of inward humility; it therefore shares the character of a heart-duty rather than that of an external object-centered act.

Meiri, Beit HaBehirah to Yoma 73b, explains that affliction is not an independent positive enjoyment or construction but a withdrawal. Eating is prohibited by the sanctity of the day, and the person’s fulfillment consists in refraining. Blessings were instituted upon the “something,” the active repair of reality; affliction is expressed through the “nothing,” through stepping back.

Among the Aharonim, several distinct explanations are developed.

Sdei Hemed, section on Yom Kippur, raises the central difficulty: if affliction is a full Torah positive commandment, why should it differ from shofar or sukkah? He answers that Sages generally fixed a blessing over an identifiable act, such as taking the lulav or wrapping in tzitzit. A command fulfilled through refraining has no single action over which to bless. If one imagined a blessing over what one does not do, every moment of inactivity would potentially become a new object of blessing, without limit.

The Hida, in Yafeh LaLev, citing the Rashba’s principle, offers a moral explanation: one does not recite a blessing over a mitzvah whose function is to repair sin. Just as there is no celebratory blessing over returning stolen property as a correction of wrongdoing, so too the Yom Kippur fast comes to cleanse sins. At the very hour when a person stands before his Creator in shame and brokenness, a festive formula of self-congratulating performance is not the central language. The fast is undertaken through humility.

The Hida adds a third reason: a blessing before a mitzvah is most suitable when its completion can reasonably be expected. The Yom Kippur fast lasts from evening to evening, and there is always a possibility that illness or dangerous weakness will force a person to eat. If one blessed at the beginning and later had to break the fast, the earlier blessing could appear disconnected from a completed mitzvah.

Sdei Hemed questions this last explanation. If the concern is failure to complete the fast, why not recite a blessing later in the day, perhaps at Minhah, once most of the fast has already passed? When one cannot bless before a mitzvah, there are cases where blessing during performance has relevance. The fact that no such blessing exists even later suggests that the primary reason lies in the passive nature of the mitzvah rather than in fear that the fast might be interrupted.

Minhat Hinukh, mitzvah 313, develops the idea that affliction is a continuous mitzvah fulfilled at every moment of the day. A mitzvah blessing ordinarily requires an act with a defined beginning and recognizable performance. Since fasting is not a one-time act but an ongoing state, every moment renews the fulfillment and there is no realistic possibility of attaching a separate “before performing it” blessing to each one.

Later thinkers deepen the spiritual meaning of the silence.

Mishnah Berurah, in the laws of Yom Kippur, describes the day as one of cessation and withdrawal from worldly concerns. The absence of a mitzvah blessing over affliction can itself reflect the angel-like state of the Jew on that day. Angels do not eat and do not relate to physical pleasure in the ordinary human way. On Yom Kippur the very state of existence becomes part of the mitzvah; the person is not merely performing an isolated act.

Rabbi Yosef Dov Soloveitchik, in Shiurim LeZecher Abba Mari, distinguishes between the “fulfillment” of a mitzvah and the concrete “act” of the mitzvah. On Yom Kippur, affliction is a fulfillment of repentance and atonement, but it has no sharply defined positive act. Sages instituted blessings primarily around active mitzvah-performance. Here the mitzvah is existential: a whole climate of withdrawal in which the person lives through the day.

My teacher Rabbi Asher Weiss, in Minhat Asher on the festivals, explains that the fast is an external expression of the inner duty to subdue desire. The essential mitzvah is connected to regret and inward submission; abstention is the vehicle. Since the heart’s work is primary and the physical abstention is its instrument, no separate blessing was established as though the fast were an independent object. On Yom Kippur, the human being himself becomes the vessel of the mitzvah.

Maran Rabbi Ovadia Yosef, in Hazon Ovadia, Yamim Nora’im (p. 267), cites and evaluates the explanations of Sdei Hemed and the Hida. He emphasizes the principal foundation that we do not bless over passive abstention. Even if one defines affliction as a positive command, the additional concern that a person may become dangerously ill and need to eat reinforces the Sages’ decision not to fix a blessing whose completion remains dependent upon the whole day. Yom Kippur seeks a broken and contrite heart more than a formula celebrating bodily deprivation.

My teacher Rabbi Shmuel HaLevi Wosner, in Shevet HaLevi (part 4, no. 54), explains that Yom Kippur affliction is not merely refraining from food; it helps define the day as a “Sabbath of Sabbaths.” Just as we do not recite a blessing over refraining from labor on Shabbat, even though “you shall rest” has a positive dimension, we do not recite one over affliction. Cessation from labor and bodily pleasure create a space in which the person is available entirely for God; in such a space silence itself becomes a blessing.

These foundations have practical consequences.

First, a sick person who must eat on Yom Kippur because of danger to life is exempt from the fasting obligation to the extent necessary for his health. There is therefore no blessing over “affliction” in his case either. When he eats permissibly, he recites the ordinary food blessings as required. This highlights the distinction: over a positive act of eating there are blessings; over abstention there is silence.

Second, the problem of reaching one hundred blessings on Yom Kippur remains real because the meal blessings are absent and no blessing was instituted over fasting. One therefore seeks other permitted ways to add blessings, such as fragrances or answering to blessings in the synagogue. The absence itself becomes part of the architecture of the day.

Third, the beginning of the fast raises an interesting conceptual point. If a blessing had existed, it would normally have to be recited before the mitzvah begins. In practice, the inward acceptance of the fast before sunset is the threshold of the mitzvah. Some people consciously think or say that they accept upon themselves the Torah commandment of affliction, creating a link between intention and abstention without inventing a blessing the Sages did not institute.

Fourth, the prayer “Aneinu” demonstrates the difference between prayer and a mitzvah blessing. Aneinu is a plea for mercy in the context of fasting, not a declaration “I am now performing a mitzvah.” The fact that prayer-language exists while no blessing was instituted teaches that the heart of Yom Kippur is turning to the Creator from within constriction, not celebrating the bodily deprivation itself.

The conceptual depth is that sometimes the greatest closeness to God occurs not through a physical object or an active deed, but precisely through “absence.” Abstaining creates a space within material life so that the soul can expand. A blessing ordinarily accompanies human action that sanctifies the external world. Yom Kippur asks the person to repair the internal world. When the soul stands exposed and cleansed, fixed verbal formulas can even seem too narrow to describe the entire existential state.

The category of a mitzvah associated with sin-repair adds another layer. A blessing often carries holy joy in obeying the command. But on the day of “For on this day He will atone for you,” the moral compass points toward humility. Affliction is not an achievement to display; it is medicine for a wounded soul. The absence of a blessing can therefore itself express awe. The person does not boast of his fast. He submits to it as part of returning to his source.

Thus silence becomes the deepest blessing. It testifies that a person surrenders to the Divine will without needing to turn the experience into self-affirming language.

In the inner world, encountering Yom Kippur affliction without a festive verbal blessing creates a moment of naked truth. The person feels bodily weakness. Yet inside the empty space created by refraining from food, there is room for faith. The real work is not the external ceremony of blessing but inward submission. The silence at the beginning of the fast asks: am I fasting merely to discharge a technical obligation, or am I creating an empty vessel in which divine mercy can dwell?

The psychological discipline here is self-nullification and humility. As the Hida explained, affliction comes in the context of sin. A person on this day is not a proud “mitzvah performer” crowning himself with a blessing, but a child returning to his Father with a broken heart. The fast points beyond words and teaches that holiness can exist in what we choose not to do. Faith is tested by the ability to become a “mitzvah-object,” so to speak, without external declarations. The reduced, afflicted state becomes a silent hymn of praise.

Morally, the absence of a blessing teaches integrity and gentleness of spirit. True holiness does not always require applause or recognition. It is measured by willingness to reduce oneself for a higher value. The silence of the blessing can express the height of personal responsibility: one does not “celebrate” suffering or deprivation, but accepts them humbly as part of repair. Even when fulfilling a Torah obligation, one should do so with awareness of deficiency and desire to improve, not with superiority.

A further moral value is the distinction between “doing” and “being.” A blessing marks an act. Yom Kippur demands a state of pure being before God. Can I stand with an exposed heart, without formulas as intermediaries, and accept the yoke of the mitzvah through silence? The higher discipline is the ability to act through quiet restraint and understand that the non-action of affliction is itself a morally refining deed.

From this issue we can draw guidance for the entire year. First, service of God is not measured only by visible acts and loud words; sometimes its peak lies in the “nothing,” in a person’s ability to contract desire and make room for the Divine Presence through silence and submission. Second, the inner compass must constantly be directed toward humility; when a mitzvah comes in the context of cleansing sin, that awareness protects us from pride in our religious performance. Third, our responsibility is to make our whole being into a vessel of mitzvah, so that life is infused with holiness even when we hold no physical ritual object and recite no special formula.

The Main Point:

Why is there no blessing over the mitzvah of Yom Kippur affliction? The authorities develop three central foundations. Sdei Hemed explains that a blessing was generally instituted over an active mitzvah-deed, while fasting is fulfilled through “sit and do not act”; there is no single deed over which to bless, and one cannot attach an endless series of blessings to every moment of not eating. The Hida, drawing on the Rashba, adds a moral dimension: because affliction serves the repair of sin, it is inappropriate to celebrate it with the standard formula of a mitzvah blessing; it belongs to shame, humility, and brokenhearted repentance. He also notes the possibility that a person may have to break the fast because of sudden illness, so its completion is not assured at the outset. Sdei Hemed questions that last reason, but the broad agreement remains that Yom Kippur holiness is built through abstention rather than active performance.

On Yom Kippur, in a profound sense, we become the mitzvah itself. Just as the altar does not bless over the offerings placed upon it, the person who is being purified through fasting does not require an additional blessing over his own sacred state. His very existence in those hours becomes a song of praise and purification before the Creator.
