Rabbi Yehuda Leib Halevi Ashlag, is one of the greatest Kabbalists of the 20th century. He established a new method in Kabbalah and his teachings represent the main avenue for studying the Book of the Zohar and Kabbalah today.


Rabbi Ashlag is known as "Baal HaSulam" named after his monumental work "The Sulam" commentary, in which he clarified and explained the entire Zohar, and made it and the Kabbalah understandable to the world for the first time ever.

Rabbi Ashlag was born in Likova, Poland, a disciple of the Admor Rabbi Meir Shalom Rabinowitz of Kaluszyn, of his son, Rabbi Yehoshua of Porisov, and of the Admor of Belz. He was ordained a rabbi and served as a Dayan and teacher in Warsaw for a number of years while involved in the learning of the wisdom of Kabbalah from a very young age. In 1921 the Rabbi made Aliyah and settled in the old city of Jerusalem.

It is believed that he warned about the Holocaust before it took place, and cried out that the destruction of the world is imminent in the days of the First World War. In his efforts to overcome this the rabbi suggested the study of Kabbalah in Yeshivas. His actions and thoughts were devoted to repairing human society as a whole and believed that this could be done solely through the wisdom of Kabbalah.

Apart from the commentary on the Sulam, he wrote many essays on Kabbalah including his dissertation on the great 'Talmud Ten Sefirot' providing a new understanding of the Ar'i Kabbalah doctrine. Rabbi Ashlag promoted his ideas both in theory and in practice. He met with political leaders and public figures to try and create connections with the Kibbutz movement.


Rabbi Ashlag had a tremendous influence on Judaism, Kabbalah in particular, and has become a domain for millions of people all around the world–Jews and non-Jews alike and was considered a universal thinker by many recognized philosophers during his time. Rabbi Ashlags influence is only growing and paving the way to many people around the world. His revolutionary thinking brought humanity a closer and unprecedented relationship with the Jewish doctrine Kabbalah.


Centers for the study of his teachings can be found all over the world and operate based on spreading his ideas to a wide and diversified audience. Rabbi Ashlag passed away at 70 years old (less than a week after his birthday).
