Based on first hand experience and written for the serious occult practitioner, the language is antiquated but the information is clear and accurate. Most of the book explains and defines different forms of psychic attacks, including those elements found in mental illness. Explanations are accompanied by fascinating anecdotes and the methods for combating psychic attacks are easily followed and sensible. Practical and written with humor, Fortune herself felt this book was her greatest written work. ~review by Lisa Mc SherryAuthor: Dion FortuneSamuel Weiser Inc., 1999 (reprint)
