Kabbalist Yehuda Ashlag (Baal HaSulam)

Rabbi Yehuda Leib HaLevi Ashlag (1884-1954) is known as Baal HaSulam (Master of the Ladder) for his Sulam (ladder) commentary on The Book of Zohar. Baal HaSulam dedicated his life to interpretations and innovations in the wisdom of Kabbalah, disseminating it in Israel and throughout the world. He developed a unique method to the study of Kabbalah, by which any person can delve into the depth of reality and reveal its roots and purpose of existence.

Baal HaSulam's teacher was Rabbi Yehoshua of Porsov. In 1921, Baal HaSulam immigrated to Israel and settled in the Old City of Jerusalem. The word of his coming quickly spread among Jews who emigrated from Poland, and he soon became known as an authority in Kabbalah. Gradually, a group of students formed around him, attending Kabbalah lessons in the wee hours. Later on Baal HaSulam moved from the Old City and settled in Givat Shaul, which was then a new neighborhood in Jerusalem, where for several years he served as the neighborhood rabbi.

Baal HaSulam spent the years 1926-1928 in London. During his time in London he wrote the commentary to the Ari's Tree Of Life - Panim Meirot uMasbirot, which he printed in 1927. Throughout his stay in London, Baal HaSulam conducted extensive correspondence with his students in Israel, which were assembled in 1985 in a book titled Igrot Kodesh (Letters of Sanctity).

In 1933 Baal HaSulam published the tractates Matan Torah (The Giving of the Torah), HaArvut (The Bond), and HaShalom (The Peace).

Baal HaSulam's two major works, the result of many years of labor, are Talmud Eser Sefirot (The Study of the Ten Sefirot), a commentary on the writings of the Ari, and Perush HaSulam (The Sulam Commentary) on The Book of Zohar. The publications of the 16 parts (in six volumes) of Talmud Eser Sefirot began in 1937. In 1940 he published Beit Shaar HaKavanot (The Gatehouse of Intentions), with commentaries to selected writings of the Ari. Persuh HaSulam on the Zohar was printed in 18 volumes in the years 1945-1953. Later on Baal HaSulam wrote three additional volumes containing commentaries on The New Zohar, whose printing was completed in 1955, after his demise.

Baal HaSulam wrote a series of introductions that prepare the student for proper study of Kabbalistic texts. Some of these introductions are Preface to the Book of Zohar, Introduction to the Book of Zohar, Preface to the Wisdom of Kabbalah, Preface to the Sulam Commentary, General Preface to the Tree of Life, and Introduction to Talmud Eser Sefirot.
