Chassidut is a spiritual movement within Judaism that originated in the 18th century, founded by Rabbi Israel Baal Shem Tov. It emphasizes the importance of personal connection to God, joy in religious practice, and the value of community. Chassidut teaches that every individual can achieve a deep spiritual experience through prayer, study, and good deeds. The movement is characterized by its teachings on the inner dimensions of Torah and the significance of the tzaddik, or righteous leader, who guides followers in their spiritual journeys. Chassidut has various sects, each with its own customs and practices, contributing to the rich diversity of Jewish life.
