Also known as “Baal Ha-Sulam” [the name of his magnum opus] Rabbi Yehuda Leib Halevi Ashlag (1886-1954)
From their website: Kabbalah - the world's oldest body of spiritual wisdom - contains the long-hidden keys to the secrets of the universe as well as to the mysteries of the human heart and soul. Kabbalistic teachings explain the complexities of the material and the nonmaterial universe, along with the physical and spiritual nature of all humanity. Kabbalah shows in detail how to navigate that vast terrain in order to remove every form of chaos, pain, and suffering. For thousands of years, the great kabbalistic sages have taught that every human being is born with the potential for greatness. Kabbalah is the means for activating that potential. Kabbalah was always intended to be used, not just learned. Its purpose is to bring clarity, understanding, and freedom to our lives - and ultimately to even erase death itself. Kabbalah Centre International extends the invitation for learning to everyone, no matter what their situation. We also offer scholarships to those with a strong desire to learn and share Kabbalah, but who may not have the means to study it.
