Remote viewing is defined as "a human perceptual ability to access, by mental means alone, information blocked from normal perception by distance, shielding, or time." Put more simply, a remote viewer makes use of intuition to perceive targets (objects, events, or other types of information) safeguarded from the remote viewer's other five senses due to either great distance (the target exists on the other side of the world), shielding (the target is inside a locked steel vault), or time (the target exists either in the future or the past). The psychoanalyst Carl Jung demonstrates that before extra-sensory perceptions can be understood, normal sensory perceptions must be explained. Carl Jung reveals how unconscious archetypes make both sensory and extra-sensory perception possible. Synchronicity, as an acausal connecting principle between mind and matter reveals a mind-matter continuum establishing not only a link between mind and space but also between science and divination. It is this synchronistic and divinatory linkage that makes remote viewing possible.
