Amidst the rich panoply of Jewish Kabbalah, Abraham Abulafia (1240-1291) resonates the most with modern, philosophically minded seekers of direct mystical experience. Abulafia was unique amongst Jewish mystics in providing precise instructions for personal spiritual practice. Despite a severe rabbinical ban, the subterranean influence of Abulafia’s complex of ideas and meditation techniques is evident upon many central figures in the history of Religion and Philosophy, including Chaim Vital, Pico della Mirandola and Spinoza.
