"This book demonstrates the complexity of Jewish mysticism in the history of religions. The author provides a morphology of the deep structures of thought that emerge from the basic texts of Jewish mysticism. Combining the most sophisticated philological and phenomenological methods, he explores fundamental issues."The author offers many contributions to a variety of topics in Jewish mysticism. Each chapter stands by itself, but the whole book has a unified hermeneutical approach." — Moshe Idel, Hebrew University"Wolfson is one of the most astute interpreters of kabbalistic sources. I was struck, first, by the precision and care with which he analyzes the primary sources, and second, by the tremendous insight with which he explores familiar concepts and leads the reader to re-envision the material in nuanced, subtle ways. This book brings to light hitherto unexpected connections among a variety of symbolic complexes." — Barbara A. Holdrege, University of California, Santa Barbara
