The Light of the Zohar
Ahavas YisroelTorah learning
Rav Tzvi Hirsch said, "One who never saw the light of Sefer HaZohar never saw a light in his life." For him the Zohar was not an optional study for specialists. He urged every Jew to learn it, together with the Kisvei HaAri, as the source from which Chassidus draws its light.
