Exorcist: A Brief Introduction to Evil Spirits and How to Fight Them is a powerful guide that blends history, folklore, and lived practice to illuminate humanity’s oldest struggle—the battle with dark spirits. Drawing from traditions as diverse as African rootwork, Haitian Vodou, Sufi mysticism, and Catholic exorcism, it traces how cultures across the world have understood demons, from the jinn of Islam and the dybbuk of Jewish lore, to the asuras of Hindu cosmology and the legions of Christian tradition. More than just an introduction, this book equips the reader with practical tools: prayers, incantations, herbs, and ritual techniques for banishing malevolent forces and strengthening spiritual defenses. Written in a voice that is at once scholarly and ancestral, it offers both a window into demonology across cultures and a handbook for those who feel called to confront the darkness directly.
