Book excerpt: Fresh ideas for the modern mage lie at the heart of this thought-provoking guide to magic theory. Approaching magical practice from an information paradigm, Patrick Dunn provides a unique and contemporary perspective on an ancient practice. Imagination, psychology, and authority-the most basic techniques of magic-are introduced first. From there, Dunn teaches all about symbol systems, magical artifacts, sigils, spirits, elementals, languages, and magical journeys, and explains their significance in magical practice. There are also exercises for developing magic skills, along with techniques for creating talismans, glamours, servitors, divination decks, modern defixios, and your own astral temple. Dunn also offers tips on aura detection, divination, occult networking, and conducting your own magic research.
