Israel Sarug
Israel Sarug Ashkenazi was a pupil of Isaac Luria who devoted himself at the death of his master to the propagation of Lurianic Kabbalah, through which he gained many adherents in various parts of Italy. Among these, the most prominent were Menahem Azariah da Fano, whom he persuaded to spend large sums of money in the acquisition of Luria's manuscripts; and Aaron Berechiah of Modena, author of the Ma'avar Yabbok. Sarug also lectured in various places in Germany and in Amsterdam. In the latter city one of his disciples was Abraham Cohen de Herrera.
Sarug's school of Kabbalah has produced several major texts, of:
- Limudei Atzilut, the major compendium of Sarugian teachings on Kabbalah
- Drush HaMalbush, another major publication in the Sarugian worldview
- Kabbalah, a Kabbalistic essay published in the Matzref LaChochmah of Joseph Delmedigo
- Hanhagot Yisrael, or Tikkun Keri/Keri Mikra, a methodology of asceticism
- Kuntres Ne'im Zemirot Yisrael, a commentary on three of Luria's piyyutim for Shabbat
- Gilgulei ''Neshamot'', published under the name of Menahem Azariah da Fano, a collection of traditions regarding identifications of soul transmigrations
Sarugian Kabbalah
Key concepts in the exposition of Sarugian Kabbalah revolve around the Olam HaMalbush, an early emanation of Creation between Ein Sof and Adam Kadmon that provides the context and locale of all subsequent emanations.
Opposition to Sarug's system came from the accepted school of transmission of Luria's Kabbalah, whose chief expositor was Hayyim Vital. Today, while most students of Kabbalah learn the systems descended from Vital's authentic transmission of Luria's teachings, there remain certain schools, especially among Hasidic and Sephardic traditions, that maintain a syncretic approach between Vital and Sarug's systems. This is especially noticeable in Chabad, and is made explicit in the thought of Yitzchak Meir Morgenstern.
