By Rabbi Yair Hoffman


It is an unfortunate reality that there are many nice people out there who may have something rather serious hanging over them. That something is the Divine punishment known as kareis — being cut off. This penalty is associated with a number of violations: desecrating Shabbos, improper relationships, eating blood, breaching the prohibition of niddah, eating on Yom Kippur, eating cheilev, going to prohibited places on Har HaBayit … the list goes on.

The Question

Kareis is quite serious. But can anything be done? Is there a means by which kareis can be rectified? If so, how? And why haven’t we heard about it before? Is there a particularly propitious time for it?

The answer to this question, fortunately, is yes. And with the yom tov of Shavuos approaching, there is now a possibility of double-dipping. But there are other requirements.

Learning All Night

The great Arizal, Rabbi Yitzchak Luria (Shaar Ruach HaKodesh, p. 11b) describes a rectification ritual known as tikkun kareis. He writes as follows: “One who is awake all night and does not sleep at all, and immerses himself in the study of Torah that entire night will exempt himself from one punishment of kareis if, Heaven forbid, he has incurred it. Each night exempts one kareis.”

So here we have it. One night of all-night learning can rectify one violation that would incur kareis.

The Thinking Process

Rav Chaim Vital, the foremost student of the Arizal, adds more information about the exact kavanos, intentions, that one must have while learning Torah for the rectification. One must connect his neshamah to the root above, thus rectifying adam elyon. Practically, this means that he should focus and picture his neshamah connecting to and originally emanating from the upper heavenly sphere.

The Four Caveats

Other caveats that Rav Chaim Vital adds are to refrain from (1) haughtiness, (2) anger, (3) being overly strict with people, and (4) lashon ha’ra. It is worthwhile to study an overview of each of these middos and actions to ensure that one does not violate them.

What To Study

Rav Alexander Ziskind of Grodno (d. 1794), author of the Sefer Yesod V’Shoresh HaAvodah (Shaar HaKollel), adds to this. He writes that it is proper to study a subject that is related to the sin that one has committed, and that there are some propitious times for this ritual. The two most propitious times are during the Yamim Nora’im and during the weeks of Shovevim Tat.

What is Shovevim Tat? It is a special time when teshuvah is more effective, the weeks that we read Sh’mos, Va’eira, Bo, Beshalach, Yisro, Mishpatim, Terumah, and Tetzaveh. The names of these parshiyos form the acronym “Shovevim Tat,” which means “those who return.” He also adds that, ideally, one should perform this tikkun while standing.

Other Sources

Does anyone else discuss this tikkun? Do any rabbinical texts and sources reference it? Are there any non-chassidish and non-Sephardic gedolim who discuss it?

The answer is yes. The Chofetz Chaim discusses it. But first some background.

The Rif (Rabbi Yitzchok Alfasi) is known for his commentary summarizing the more pertinent aspects of the Talmud for us. The problem is, he did not write such a work on the order of the Talmud known as Kodshim. To help fill this lacuna, the Chofetz Chaim wrote such a work, called Likutei Halachos. In the beginning of Maseches Kerisus, the Chofetz Chaim references this custom cited in the Kabbalistic texts of tikkun kareis.

Something Else To Study

The Chofetz Chaim adds the following words after he discusses the minhag of tikkun kareis: “It is certain that if a person learns the entire maseches that deals with the punishment of kareis and the ways to avoid it, it will be enormously effective in cleansing his neshamah.” He further adds that it is especially true if he knows it well. There are 28 pages in Kerisus (and it is only one volume in the ArtScroll), so it should not be stupendously difficult to master.

A List Of Fasts

The Arizal also provides a list of sins with a corresponding number of fasts that will atone for those sins (also in Shaar Ruach HaKodesh). The commentators ask (see Ohr LeTzion Vol. III, Ch. 30) an interesting question. Do these fasts atone for every instance of that particular sin, or is the entire cadre of fasts listed necessary for every instance of violation of each sin? Perhaps there is a sort of “all-day pass” that requires more fasts, but not the entire list for each violation?

It seems that the answer to this question is cause for debate among halachic (or Kabbalistic halachic) authorities. The first Lubavitcher Rebbe, Rabbi Shneur Zalman of Liadi, writes in chapter three of his Iggeres HaTeshuvah (found in the Tanya) that  one fasts three times the amount listed in the Arizal’s list, the entire aveirah is fully atoned for. Rav Yosef Chaim, in response Rav Pealim (Vol. III, No. 35), writes that one only needs to follow the Arizal’s formula once to atone for each violation of that sin in the past.

Redeeming Fasts With Tzedakah

There is also an accepted practice to redeem the fasts with tzedakah. This practice is cited by the Mishnah Berurah, the GraZ, and the Kaf HaChaim (O.C. 119:15). To calculate the proper amount, one must figure out the portion cost per meal (for that day) and multiply it by the numbers listed by the Arizal. He also points out that one cannot mix tikkunim; each fasting for a particular sin must be kept separate.

Only After Age Twenty

The punishment of kareis is only for prohibitions one committed after the age of 20. So even though one is certainly liable for sins committed at age 13–20 (12–20 for girls), the punishment of kareis does not begin until one’s 20th birthday. Some authorities read the Rambam as being of the opinion that liability for kareis begins at 13; they infer this from what he writes in the laws of milah, that from age 13 if one did not yet have a b’ris milah he must do so, and if he does not, he is chayav kareis. However, the Rambam clearly writes in his commentary to the seventh chapter of Sanhedrin that the period for incurring kareis begins at age 20.

No Prerequisite Of Warning

To be liable for kareis, there is no prerequisite of hasra’ah (warning). Since the punishment is meted out by Heaven, it is clearly known in the heavenly courts what the perpetrator’s intentions were.


There are steps by which one can recover from a violation requiring kareis. They involve sincere repentance, special kavanos, and all-night Torah study. Ultimately, it is worthwhile to pursue, since Hashem does not want the death or destruction of those who sin. Rather, He desires our penance and return to Torah and His ways. The yom tov of Shavuos is coming up and it gives people an opportunity to learn all night. We should take advantage of it.
