Rav Yehuda Leib Ashlag
Rabbi Yehuda Ashlag (1885—1954) or Yehuda Leib Ha-Levi Ashlag also known as the Baal Ha-Sulam “Author of the Ladder” considered by many to have been a great Kabbalist and a great follower of Rabbi Isaac
Luria. This high esteem is related to his written Sulam commentary on the Zohar, and his Talmud Eser Sefirot, which today is regarded as the core of the entire teaching of Kabbalah, and hundreds of articles.
