of 16th century Kabbalist Rabbi Isaac Luria. This is a comprehensive exposition of the system of the upper worlds, Partzufim and Sefirot, in the scientific language of Kabbalah which was developed by Luria. As a core Kabbalistic text, it is especially unique in its utmost precision to detail to the structural organization and processes occurring in the upper worlds. It is set out as a comprehensive textbook, complete with commentaries, a section in each chapter dedicated to further reflection upon the commentaries, definitions of terms, tables of questions and answers, an introduction clarifying how to study Kabbalah in the correct manner, and also a summarized preface of the entire text. His other masterwork was his Sulam commentary on The Zohar, which earned him the name “Baal HaSulam”. This monumental work took him ten years to complete, written between the years 1943 and 1953. It includes a translation of The Zohar from Aramaic to Hebrew as well as an extensive interpretation. Rabbi Yehudah Tzvi Brandwein was a foremost disciple of Rabbi Yehudah HaLevi Ashlag (Baal HaSulam). His vast knowledge of the Lurianic system of Kabbalah enabled him to codify and edit the entire writings of the Ari HaKadosh, Rabbi Yitzchak Luria. He continued with a similar style of translation and commentary of Rabbi Yehudah Ashlag known as Maalot HaSulam (Extension of the Ladder) on those works of Rabbi Shimon bar Yochai, which Rabbi Ashlag didn't complete during his lifetime, namely Hashmatot HaZohar (Various other Writings) and Tikkunei HaZohar. Another publication is the notebook of Yehuda Ashlag's son and disciple, Baruch Ashlag. His notebook, entitled Shamati (I Heard]), contains over two hundred articles which were copied down from lessons and talks with his father. Baruch Ashlag kept this notebook with him in secret, until he was on his deathbed, in 1991. It was later published in Hebrew and has been translated into many different languages. The articles in Shamati form a unique kabbalistic work in their emotional depth of capturing the inner processes that a Kabbalist goes through on the path of spiritual attainment.
