In 1845, a century after the Chassidic revolution, Rav Yisrael Salanter outlined his program for ethical rejuvenation of traditional Judaism. Chassidut elevated Judaism from the depths and transformed it into something vibrant and alive. Rav Salanter hoped that Mussarwould do the same for Lithuanian Jewry. He envisioned the defeat of the Enlightenment, not by attack or by disputes, but through the inner reconstruction of the traditional camp on superior ethical and behavioral standards.
Much like Chassidut, the language and outer garb of Mussar was new, but its inner core was as old as Sinai. The Torah teaches us to be ethical, but somehow this area had fallen into neglect. Rav Yisrael set out to correct this. He was acutely aware of traditional Jewry's social and educational failings. His philosophy was, "First repair yourself and then reach out to others." He advocated caring about other people's material wellbeing. This in turn would affect their spiritual level.
Rav Salanter advocated that Mussar should be studied in a beit hamussar, a room allocated for the purpose. The teachings were meant to be intoned with lips aflame, with a haunting tune that would carve the words into one's heart.
Someone once asked Rav Salanter's wife if she found it difficult to live in the presence of such a towering tzaddik. She replied that there had never been a problem at all. From the beginning of their marriage Rav Yisrael laid down a very clear rule, all material matters were to be her province and all heavenly matters would be his province. In the course of time she discovered that with Rav Salanter everything was heavenly. There was nothing physical in his realm that was divorced from its spiritual connection.
Before his students went to bake matzot, they asked Rav Yisrael what stringencies to follow. He told them to be careful to keep the bakery clean and not to raise their voices. The proprietor of the bakery was a widow and if they caused her anguish all their good intentions would be lost.
One Friday night a Jew invited Rav Salanter to his seudah. When they arrived home, he noticed that the challot were uncovered. He called out sharply to his wife. She quickly defended herself by saying that she had been about to cover them. Rav Salanter asked his host, "Why do we cover the challot?" He answered, "Everyone knows that it is in order not to shame them." Rav Salanter then countered, "Is shaming your wife ok?"
The Gemara teaches that the more water one pours for netilat yadayim, the more blessing one brings down from heaven. Rav Salanter once attended a wedding where he poured just enough water to meet the minimum standards. He explained, "I cannot be stringent on the water carrier's account."
Rav Salanter taught, "There's only one person in the world I can rectify and that person is me." His idea to create a mass ethical movement that would change people's lives did not materialize. However, he did succeed in imparting his legacy to several prime students who later went on to found the three leading schools of Mussar: Slabodaka, Novardok, and Kelm.
