Psychic Self-Defense: The Classic Instruction Manual for Protecting Yourself Against Paranormal Attack

The definitive classic on protection from psychic attacks and paranormal disturbances. Dion Fortune, a trained psychologist and high-level initiate of various occult orders, provides a unique blend of psychological insight and esoteric knowledge. She describes the nature of psychic attack, how to recognize the symptoms of interference (obsession, haunting, and 'vampirism'), and practical methods for building defenses. The work is famous for its semi-autobiographical accounts of Fortune's own experiences with manipulative occultists and her emphasis on the 'common sense' approach to spiritual hygiene.
