The Kabbalah Unveiled - S. L. MacGregor Mathers - The Kabbalah Unveiled is a book concerning Kabbalah by freemason and occultist by S. L. MacGregor Mathers. Kabbalah is an esoteric method, discipline, and school of thought in Jewish mysticism. It is a set of esoteric teachings meant to explain the relationship between the unchanging, eternal God-the mysterious Ein Sof ("The Infinite")-and the mortal, finite universe (God's creation).It forms the foundation of mystical religious interpretations within Judaism. Historically, Kabbalah emerged from earlier forms of Jewish mysticism, in 12th- to 13th-century Spain and Southern France, and was reinterpreted during the Jewish mystical renaissance in 16th-century Ottoman Palestine. Jewish Kabbalists originally developed their own transmission of sacred texts within the realm of Jewish tradition. The Kabbalah Unveiled includes translations and commentaries of the books of Zohar: The Book of Concealed Mystery; The Greater Holy Assembly; and The Lesser Holy Assembly.Samuel Liddell (or Liddel) MacGregor Mathers (8 or 11 January 1854 - 5 or 20 November 1918), born Samuel Liddell Mathers, was a British occultist.
