Pardes Rimonim is a classic work of authentic Kabbalah penned by the preeminent scholar, Rabbi Moshe Cordevero (Ramak). A powerful intellect, fertile writer, and gigantic figure in Kabbalah, Ramak (circa 1520-1570) distinguished himself first in Talmudic studies while under the tutelage of Rabbi Yosef Caro. However, he began his Kabbalah studies at age 20 with Rabbi Shlomo Alkabetz, who was both his brother-in-law and composer of Lecha Dodi. In the Pardes, Ramak also displays a marked philosophical influence by the Rambam (Rabbi Moshe Ben Maimon, i.e. Maimonides). Indeed, Ramak's encyclopedic work in Kabbalah heralded the renaissance of kabbalistic genius that emerged after him in Safed. A comprehensive work collecting the kabbalistic learning of that time, the original Hebrew version of the Pardes was a single volume composed of 32 parts and was written in both Hebrew and Aramaic.

Maimonides' vision of Judaism was deeply elitist, but at the same time profoundly universalistic. He was highly critical of the regnant Jewish culture of his day, which he perceived as so heavily influenced by ancient Jewish mysticism as to be debased. While focusing on that critique, Kellner skilfully and accessibly demonstrates how Maimonides used philosophy in order to purify a corrupted and paganized religion and to present distinctions fundamental to Judaism as institutional, sociological, and historical, rather than ontological. In Maimonides' hands, metaphysical distinctions are translated into moral challenges.

"Concealed Treasure of Eden" was written by Abraham Abulafia in Sicily in 1286. Born as a lengthy commentary on Sefer Yetzirah (Book of Formation) and rich with autobiographical material, it is a real encyclopedia of prophetic Kabbalah and much more. Abulafia deepens every one of his teachings more than in any other book, and touches really every topic, spanning from meditation techniques to the holy names, from practical Kabbalah to lunar astrology, from the Sefirot to the levels of the soul, etc. The reader will find a wealth of information in this book, which is the biggest that Abulafia ever wrote.
