Rav Tzadok, or “The Kohein” as he was known amongst Chassidim, was one of the most prolific authors in the history of the Chassidic movement. Born into a non-Chassidic rabbinic family, Rav Tzadok became famous as a child prodigy authoring articles and books which later became classics. Later in life, Rav Tzadok became Chassidic and became a Chassid of the Izbitcher Rebbe. Having excelled in both the Chassidic and non-Chassidic world, Rav Tzadok’s writings became a synthesis of analytical logic and mysticism. Eventually, Rav Tzadok became the Rebbe of Lublin. His writings are treasured by scholars everywhere.
