Crystal balls have been used for at least four thousand years for divination. The art of gaining information for looking into crystal is called “scrying.” Most people associate a gypsy reading crystal ball as a symbol of mystical power. A Psychic may see different images in his or her brain whilst in a light trance. These images can be concrete pictures, symbols or vague impressions. What these images convey are information about situations you are facing and guidance of how to resolve your problems.
