Men immersing in a Mikveh daily prior to Davening Shacharis:
In today’s times, it is customary amongst Chassidim and men of piety to immerse daily in the mikvah prior to the daily prayer. Although this custom of being particular to immerse every single day prior to prayer, does not contain any clearly documented source, and was not practiced in the previous generations, nonetheless, it has become a cherished uncompromising part of the preparation for prayer and general purity of soul, and has its roots in both biblical and rabbinical precepts. Below we will explore the source and reasons behind this custom, its history, it’s purpose and effect, and various Halachos related to it.
A. Is there a source for this custom?
We do not find any documented source in the Poskim, or Sifrei Mussar and Kaballah, or even Sefarim of the Chassidic masters, which explicitly directs individuals to immerse in a Mikveh every single day prior to prayer, as is the custom today by the masses of Chassidic Jewry. Furthermore, based on the writings and testimony of Chassidim in the previous generation, it is clear that this custom was not practiced by the masses, although was likely practiced by select righteous individuals. Even Chabad Chassidim in previous generations, who were particular to often immerse in a mikveh prior to prayer, were not necessarily particular to do so daily. Nonetheless, this custom of daily immersion prior to prayer is encouraged to be followed today and contains strong foundation and basis in both Scripture, Talmud, Halacha, and the writings of the Hasidic masters. Its influence first began with the teachings of Mussar and Kabbalah which explain the greatness of immersion. It then gained more popularity with the teachings of the Baal Shem Tov, until eventually many Chassidim were accustomed to not pass three days without immersion. We will explore below each one of the reasons and sources that contributed to the custom today of the daily immersion prior to prayer, and explain its history, it’s purpose and effect, and various Halachos related to it.
B. Its sources and reasons in Halacha:
The scriptural basis-Immersion from impurity and for Tosefes Taharah: The concept of immersion in a Mikveh for the sake of purification is recorded explicitly in Scripture. However, in Scripture, and in biblical law, immersion is only necessary for one who is currently Halachically impure and desires to perform an act of extra sanctity, such as to enter certain areas of the Temple mount, and to eat certain sanctified foods such as Teruma, Maaser Sheiyni, and Kodshim, or for women to purify from Nidda. It, however, is not required to be done prior to prayer. Nonetheless, we do find in one area scriptural basis for immersion even not for the sake of ritual and Halachic impurity but for the sake of further purity, and that is regarding the five immersions of the high priest on Yom Kippur, which was for the sake of additional purity in the Temple. From here we can derive that there exist two purposes in the immersion in a Mikveh: 1) for the sake of purifying a person from an impurity. 2) For the sake of adding further purity to an already pure person. Now, the morning immersion prior to prayer can serve one or both purposes; to purify one from impurity [i.e. Keri, as explained next], or simply for additional purity.
Talmudic basis: The Mishneh states that the priests would need to immerse in a Mikveh each morning upon entering the Azara prior to performing temple service. Regarding the morning washing, the Poskim compare a Jew’s awakening in the morning to serve God, similar to a priest doing service in the temple, and use this comparison to explain why we are required to wash our hands daily upon awakening. Now, just as we are compared to priests who are serving God regarding the morning washing, so too, we can be compared to them regarding the daily immersion and hence from here we can find a root and source for the daily immersion prior to prayer, just as was done by the priests in the temple.
Baal Keri-The Takana in the times of Ezra: The concept of immersing in a Mikveh prior to prayer was first introduced by Ezra who stated that all men who are a Baal Keri [expelled seed] must immerse prior to prayer. In addition to the fact that Ezra’s institution was limited specifically to the Baal Keri, furthermore, this institution itself was rejected by the populace, and is not Halachically binding, even though it is encouraged to be practiced. Hence, there exists no obligation, or even source from the times of Ezra, for the daily immersion practiced today.
Teshuvah-The Tevila of a Baal Teshuvah and Ger: It is well known, that according to Halacha, a convert is Biblically required to immersing in a mikvah for the sake of completing his conversion process and becoming a Jew. Drawing from this law, the sages established that also a renegade Jew who chooses to return to his people, and repent from his state of apostasy, must immerse in a Mikveh. From here we can derive that immersing in a Mikveh contains intrinsic value in one’s process of repentance. This is further emphasized the law brought next regarding the immersion of Erev Rosh Hashanah and Yom Kippur.
The ruling regarding Rosh Hashanah and Yom Kippur: It is customary to immerse in a Mikveh on Erev Rosh Hashanah and Erev Yom Kippur to purify oneself from the state of Keri, and for purposes of repentance. [From here we can derive two important points: 1) Although the institution of Ezra was nullified, nonetheless, it still holds value even though it is not obligatory. Hence, from here we can learn of the value of a Baal Keri immersing in the mikvah throughout the year. 2) The intrinsic value of repentance represented in the immersion.]
Become receptacle for Divine revelation-The directives of Kaballah and the Arizal: In the teachings of the Arizal we find several additional dates [to that of Erev Rosh Hashanah and Yom Kippur] in which men are encouraged to immerse in the mikvah for the sake of achieving spiritual cleanliness and becoming a receptacle for a higher level of holiness to dawn upon them. These include, Erev Shabbos and Shabbos day, Erev Yom Tov and Yom Tov day, before Kapparos, after learning Shavuos night. From here we learn the concept that immersion is necessary in order for one’s soul to be a receptacle for Godly revelation, and hence Chassidim who desire to feel God during their prayer make sure to immerse daily prior to praying.
Bathing the body prior to prayer: The Poskim rule that one should wash his face and feet every day out of respect for G-d, as the verse states “For in the image of G-d he created man”. Now, one who goes to Mikveh in the morning fulfills this mitzvah with the immersion.
