Second edition with supplements to the first edition. [Lemberg, 1861.] Fundamental book explaining concepts in the Ar”i’s kabbalah in the Chassidic manner. The preface to the book relates that the Elder Admo”r delivered the sermons in the book each Shabbat night, and turned to his son, the Middle Admo”r, to write them down, because he knew in his soul that he would not distort their meaning; he would “hit the target and not miss.” At the beginning of the book, there is a letter which was sent to the people by the Middle Admo”r. The leaves before the title page contain many antique owners’ notations. [2] 84, 40, 31-34 [should be 20] leaves. 25 cm. Fine condition. Aging stains.
