First published in 1930, "Psychic Self-Defense" is one of the best guides to detection and defence against psychic attack from one of the leading occult writers of the 20th century. After finding herself the subject of a powerful psychic attack, famed British occultist Dion Fortune wrote this detailed instruction manual on protecting oneself from paranormal attack. This classic psychic self-defence guide explains how to understand the signs of a psychic attack, vampirism, hauntings, and methods of defence. Everything you need to know about the methods, motives, and physical aspects of a psychic attack and how to overcome it is here, along with a look at the role psychic elements play in mental illness and how to recognise them.
