Obsidian promotes energy deflection by wrapping an impenetrable shield around you, making it a valuable stone for sensitive souls and emotional empaths. It's great for calming your energies from overwhelming feelings. Use as a divination stone in the mystical arts of seeing the future and for the cleansing and transmutation of negative energies. It's sometimes called the "psychic vacuum cleaner" as it gets rid of negativity in your auric field.
