Halomancy, also known as crystallomancy or crytal-gazing, is the practice of gazing into a crystal or salt and interpreting the images seen as divination. Synonyms for halomancy include scrying, peering, soothsaying, and divination. Other similar practices include using tarot cards, runes, pendulums, and mirrors for divination purposes. The belief behind halomancy is that crystals and salt have the ability to absorb energy and reflect images that can be interpreted for guidance or predicting the future. This ancient art form has been practiced by various cultures around the world and continues to be used by many as a tool for spiritual guidance and self-discovery.
