The art of finding out hidden information about past, present or future events.  Scrying, pendulum work, tarot readings, runes and so on, are all forms of divination.  It is also a method for receiving supersensory information.  Unlike in clairvoyance, which works through the mind, here it may be expressed in muscle movements or through the interpretation of physical auguries.  In general, divination may be described as the art of disclosing the unknown through an intermediary material link.
