Sefer Etz Chaimעץ חיים
Tzfat · 1573
The systematic exposition of the Arizal's kabbalah, written down by his foremost disciple Chaim Vital. Etz Chaim is the map of the upper worlds — the doctrines of tzimtzum (divine contraction), shevirat ha-kelim (the breaking of the vessels), tikkun (repair), and the partzufim (the divine "faces") that reorganize the sefirot. Almost every kabbalistic thinker after the 16th century is in conversation with Etz Chaim. It defines the questions that the Ramchal, the Baal HaTanya, and Rabbi Chaim of Volozhin all answer in their different ways.
