Entering the Mysterious Dimensions...BEYOND SHADOW WORLDIn this, the third volume (originally published as "Our Shared World of the Supernatural") of Brad Steiger's Shadow World series, the "master of the paranormal" expands the roster of extra-dimensional beings that we share our universe with. In addition to the spirits of the dead, nature spirits, spirit parasites, and spirit mimics, he also explores the nature of the Light Beings, which include the benevolent entities known as angels, spirit guides, spirit teachers, and celestial visitors or "space brothers." Though Steiger provides techniques for contact and behavior with them, he warns that such entities should never be either worshipped or summoned - as they may not be what they claim to be.
