"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.
