Musar is a Jewish ethical, educational, and cultural movement that originated in the 19th century in Eastern Europe. It focuses on personal development and moral character, encouraging individuals to cultivate virtues such as humility, patience, and compassion. The movement emphasizes self-reflection and the study of religious texts to improve one's ethical behavior. The teachings of Musar are often explored through study groups and literature, including works by notable figures like Rabbi Israel Salanter. Practitioners engage in exercises and practices designed to enhance their spiritual growth and ethical conduct, aiming to create a more meaningful and responsible life.
