"Chasidic" refers to anything related to Chassidus, a mystical and spiritual movement within Judaism that began in the 18th century. The Chasidic movement emphasizes deep emotional connection to Hashem, joyous observance of the commandments, and a focus on the inner dimensions of the Torah.
Chasidic Jews are known for their distinct customs, attire, and community structures, as well as their devotion to a Rebbe, a spiritual leader who guides their path in serving Hashem. The teachings of Chassidus often stress the importance of unity, love for fellow Jews, and the pursuit of spiritual elevation in all aspects of life.
Chasidic groups vary in their customs and philosophies, but they share common roots in the teachings of the Baal Shem Tov, the founder of the movement. Chabad is one of the well-known Chasidic groups, known for its outreach efforts and the dissemination of Chassidic teachings to Jews around the world.
