Sefer Pitchei She'arim with Likut Me'ir HaPetach - 2 Volume Set / ספר פתחי שערים עם ליקוט מאיר הפתח - ב' כרכים

A monumental, foundational masterwork of Jewish esoteric thought (Kabbalah) that serves as a highly systematic, lucid commentary unlocking the complex concepts of the Arizal's Etz Chaim. It interprets these deep mystical ideas through the analytical traditions of the Vilna Gaon (Gr"a) and the Ramchal. This acclaimed two-volume edition is beautifully typeset and features the extensive parallel study guide and anthology Me'ir HaPetach, which aggregates critical source citations, annotations, and contextual cross-references.
