Abraham Abulafia (1240–after 1291) stands among the most original and challenging voices in medieval Jewish mysticism. This book is a rare window into his prophetic method, a short work that treats words and numbers as instruments for encountering higher reality. Long considered lost, the text has been identified by Moshe Idel as preserved in a manuscript at the Biblioteca Medicea Laurenziana in Florence (Plut. 02.48), catalogued there as Opusculum cabbalisticum, absque titulo, et auctoris nomine (“Kabbalistic booklet, with neither title nor author name”). In these pages Abulafia demonstrates how the numerical value of language opens not only symbolic insight, but a practical route to revelation. He maps a contemplative landscape - the Garden of Eden, the World to Come, and the realm of Gehenna - and describes the inner virtues and disciplines required to enter the sacred Orchard. Combining technical instruction in permutation and meditation with ethical and visionary teaching, the work is at once a manual and a map for the soul. This edition brings that teaching to light, offering careful translation and contextual commentary so that modern readers - whether academic or devotional - can engage directly with one of Abulafia's most intriguing survivals.
