Crystal balls and spheres emit energy in all directions equally and are helpful when meditating, as well as trying to connect with your innermost self. This particular shape is commonly used for scrying, a practice which dates back thousands of years. Scrying is the art of looking into a reflective surface, such as glass, water, a mirror, or a crystal, to gain mystical insight.
The images seen with a crystal ball aren’t the foretelling of future events, but rather images from deep within one’s subconscious mind, and the crystal ball is the door through which these subconscious thoughts can be accessed. When using a crystal ball, a trance-like state is induced that dissociates one’s consciousness, enabling information from the subconscious to pass through the mind’s eye. It is here the images are seen, not in the crystal itself.
