The challenge facing us in this decade is the discovery and understanding of the complex paranormal processes underlying human behavior. Because parapsychological concepts and techniques are not limited by the boundaries of physical perception and experience, they suggest new and more efficient ways to increase awareness and expand the human capacity for new knowledge and understanding.--from the Preface.This book is a survey of current beliefs about, and lines of investigation into, various kinds of psychic phenomena--extrasensory perception, objectology (the study of inanimate objects and their paranormal applications, as in dowsing), extrasensory apperception (in which external objects are related to internal processes producing new psychic insight, as in sand reading), auraology, dreamology, out-of-body experiences, psychokinesis, hypnosis, and discarnate survival.
