Meet Rabbi Chaim Vital (1543–1620), the indispensable figure who codified the entirety of Lurianic Kabbalah, ensuring its survival and transmission to the world. A distinguished scholar of Jewish law and student of Rabbi Moshe Cordovero and Rabbi Yosef Karo, Vital became the chief and most trusted disciple of Rabbi Isaac Luria (the Arizal) in Safed for the brief two years before Luria's passing. Luria himself wrote almost nothing, making Vital's comprehensive collection and organization of his master's oral teachings—primarily preserved in the seminal work Etz Chaim (Tree of Life)—the foundational text for virtually all subsequent mystical study. His writings transformed scattered revelations into a profound, systematic theology, defining concepts like Tzimtzum and Tikkun Olam and establishing the Lurianic worldview as the dominant force in Jewish mysticism for centuries.
