Sefer Brit ha-Menuḥa (Book of Covenant of Serenity)

'Sefer B'rit ha-Menuḥa' is an anonymous Kabbalistic book from the late 13th century or the beginning of the 14th century. The content of the book is best described by the alternative name  - "The Book of Lights," given to it due to its central descriptions of the journeys of Israel in the desert, and the images of the vowels of the Name of God, that are portrayed as journeys of divine lights.

The treatise describes the complete set of divine theosophical and angelologic powers in a coherent system, in order to relate and unite each name of an angel with its source, and to allow magic acts by the application of the full cosmological and divine unity.

This eclectic critical annotated edition provides, for the first time, a clear and coherent text from the book's forty four manuscripts and eight previous prints (from 1648 till recent), presents supplements and relics of the book from additional manuscripts, along with an early treatise by the same unknown author - 'Sefer ha-Gevura' (Book of Enhancement).
