Kabbalah is a term meaning the mystical side of Judaism. It is an authentic and ancient tradition passed down through the centuries by great Sages both Chassidic and other. In the 20th century one of its greatest exponents Rabbi Yehudah Lev Ashlag opened the wisdom to a wider audience in his great commentaries on the Zohar, the central book of the kabbalah and on the work of the great 15th century Kabbalist Rabbi Isaac Luria (the Ari) . His work attracted great opposition, but the great modern interest in Kabbalah starts from then. The purpose of this list is to find good authentic translations, compilations or other studies in English for the interested reader.
