Book of the Sacred Magic (Abramelin - Peterson ed.)

This text, associated with Abraham von Worms and best known through modern editions, presents a structured system of ritual magic aimed at spiritual purification and contact with holy powers. It is historically important for its influence on ceremonial magic, and readers will find detailed instructions for preparatory discipline, prayer, squares of letters, and the complex rituals surrounding the operation.

Abraham von Worms is traditionally identified with the legendary author of the early modern grimoire known as The Book of Abramelin. The text became influential in Western esotericism, especially for its system of ritual magic and spiritual purification.
