Books The Book of the Sacred Magic of Abramelin the Mage by Abraham von Worms 

The Book of the Sacred Magic of Abramelin the Mage is a medieval grimoire attributed to Abraham of Worms, a 15th-century traveler who learned a system of powerful Kabbalistic magic from the legendary Egyptian mage Abramelin. The book is presented as a letter from Abraham to his son Lamech, sharing the secrets he acquired from Abramelin, who lived a solitary life near the Nile.

The core of the book is an extended magical ritual lasting from six to eighteen months, during which the practitioner purifies themselves, maintains strict spiritual discipline, and engages in frequent prayer to achieve the "Knowledge and Conversation" of their Holy Guardian Angel. This entity then grants the magician the power to control demons and spirits, enabling effective magical workings.

The grimoire contains a variety of spells, prayers, and magical squares, including word squares with deep mystical significance. These are used for diverse purposes such as invisibility, healing, destroying enemies, and acquiring wealth, although the text cautions against misuse and emphasizes ethical conduct.
