Mussar movement refers to a Jewish ethical, educational and cultural movement (a "Jewish Moralist Movement") that developed in 19th century Orthodox Eastern Europe, particularly among the Lithuanian Jews. The Hebrew term mussar (מוּסַר, properly transliterated as musar), is from the book of Proverbs 1:2 meaning instruction, discipline, or conduct. The term was used by the Mussar movement to refer to disciplined efforts to further ethical and spiritual development. The study of Mussar is a part of the study of Jewish ethics.
The Mussar movement arose among the non-Hasidic Orthodox Lithuanian Jews, and became a trend in their yeshiva ("Talmudical schools"). Its founding is attributed to Rabbi Yisrael Lipkin Salanter (1810-1883), who was inspired greatly by the teachings of Reb Zundel Salant, although the roots of the movements can be traced to earlier developments and rabbinic personalities and their writings.
Rabbi Yosef Zundel Salant (1786-1866), or Zundel Salant, was a layman who had studied under Rabbis Chaim Volozhin and Akiva Eiger; he spent most of his life in Salantai, Lithuania. His profoundly ethical, good-hearted and humble behavior and simple lifestyle attracted the interest of Rabbi Yisrael Salanter, then a promising young rabbi with exceptional knowledge of Jewish law. Rabbi Salanter absorbed the ways of Zundel Salant, and became the de facto founder of the Mussar movement. After tutoring Rabbi Salanter, Rabbi Yosef Zundel relocated to Jerusalem (then under Turkish rule), where he refused support from public funds and made a living in the vinegar business.
After establishing himself as a rabbi of exceptional talent early on, Rabbi Yisrael Salanter soon became head of a yeshivah in Vilna, where he quickly became well known in the community for his scholarship. He soon resigned this post to open up his own Yeshiva, where he emphasized moral teachings based on the ethics taught in traditional Jewish rabbinic works. He referred to his philosophy as mussar, Hebrew for ethics.
Despite the prohibition against doing work on Shabbat (the Jewish Sabbath) Rabbi Salanter set an example for the Lithuanian Jewish community during the cholera epidemic of 1848. He made certain that any necessary relief work on Shabbat for Jews was done by Jews; some wanted such work to be done on Shabbat by non-Jews, but Rabbi Salanter held that both Jewish ethics and law mandated that the laws of the Torah must be put aside in order to save lives. During Yom Kippur (the Day of Atonement) Rabbi Salanter ordered that Jews that year must not abide by the traditional fast, but instead must eat in order to maintain their health; again for emergency health reasons. By 1850 he left Vilna for Kovno, where he founded a yeshiva based on Mussar, with a student body of 150.
In 1857 he moved to Germany, and by 1860 he began publication of a periodical entitled Tevunah dedicated to mussar. By 1877 he founded a Kovno kollel (adult education center of Jewish study). By this time his own students had begun to set up their own yeshivot in Kelme, Telz, and elsewhere.
After Salanter's death, the Mussar movement was led by disciples including Rabbi Yitzchak Blazer and Rabbi Simcha Zissel Ziv.
In the following generation, leaders of the Mussar movement included Simcha Zissel's student Nosson Tzvi Finkel of Slobodka, and Rabbi Yosef Yozel Horwitz of Novardok.
Many of Rabbi Salanter's articles from Tevunah were collected and published in lmrei Binah (1878). His Iggeret ha-Mussar ("ethical letter") was first published in 1858 and then repeatedly thereafter. Many of his letters were published in Or Yisrael, "The Light of Israel," in 1890 (edited by Rabbi Yitzchak Blazer). Many of his discourses were published in Even Yisrael (1883).
This movement began among non-Hasidic Jews as a response to the social changes brought about by The Enlightenment, and the corresponding Haskalah movement among many European Jews. In this period of history anti-Semitism, assimilation of many Jews into Christianity, poverty, and the poor living conditions of many Jews in the Pale of Settlement caused severe tension and disappointment. Many of the institutions of Lithuanian Jewry were beginning to break up. Many religious Jews felt that their way of life was slipping away from them, observance of traditional Jewish law and custom was on the decline, and what they felt was worst of all, many of those who remained loyal to the tradition were losing their emotional connection to the tradition's inner meaning and ethical core.
During this time Rabbi Lipkin wrote, "The busy man does evil wherever he turns. His business doing badly, his mind and strength become confounded and subject to the fetters of care and confusion. Therefore appoint a time on the Holy Sabbath to gather together at a fixed hour... the notables of the city, whom many will follow, for the study of morals. Speak quietly and deliberately without joking or irony, estimate the good traits of man and his faults, how he should be castigated to turn away from the latter and strengthen the former. Do not decide matters at a single glance, divide the good work among you-not taking up much time, not putting on too heavy a burden. Little by little, much will be gathered... In the quiet of reflection, in reasonable deliberation, each will strengthen his fellow and cure the foolishness of his heart and eliminate his lazy habits."
In later years some opposition to the Mussar Movement developed in large segments of the Orthodox community. Many opposed the new educational system that Lipkin set up, and others charged that deviations from traditional methods would lead to assimilation no less surely than the path of classic German Reform Judaism. However, by the end of the 19th century most opposition to Mussar withered away, and it was accepted within much of Orthodoxy.
The teaching of Jewish ethics was based in a primary sense in the ethical teachings of the Torah and the books of the Prophets of the Tanakh (Hebrew Bible), and was directly based on books written by authors such as Moses ben Jacob Cordovero and Moshe Chaim Luzzatto.
