Scrying is an art of divination where you use a reflective or illuminated surface to see images from the past, present, or future. Common mediums for scrying include mirrors, black mirrors, crystals, glass, and water. In addition to scrying,  Tim Shaw teaches classes on many different forms of divination including Ouija, dowsing and automatic writing and he's a very good teacher,  All I knew about scrying was that I wasn't very good at it, so I asked Tim to teach this class on the show so that I could find out what I've been doing wrong.  Not only did he steer me in the right direction, I learned so much more.  it's a fascinating subject and a very interesting and informative show.
