The book focuses on Abraham Abulafia's esoteric thought in relation to Maimonides, Maimonideans, and Islamic thought in the line of Leo Strauss' theory of the history of philosophy. The book surveys Abulafia's sources and concentrates on the esoteric meaning on the famous parable of the three rings, as well as Abulafia's universalistic understanding of the nature of the Bible, the Hebrew language, the people of Israel or the Sinatic revelation.
