What is Mussar?מוסר
Mussar is the Jewish literature of ethical and character development, aimed at refining traits such as humility, honesty, and self-discipline through sustained study.
Also written: Musar, Mussar seforim, Moussar
Classic works include Mesillas Yesharim — written by Rabbi Moshe Chaim Luzzatto, the Ramchal, and first printed in Amsterdam in 1740 — alongside Chovos HaLevavos and Orchos Tzaddikim. The nineteenth-century Mussar movement founded by Rabbi Yisrael Salanter made structured daily study of these works a fixture of yeshiva life, which is where much of the demand still comes from.
Mussar seforim are typically short, frequently reprinted, and heavily used, so the second-hand market is large and condition varies widely. Many are available with facing translation, which broadens the audience well beyond yeshiva students.
