Obsidian is a type of volcanic rock, a natural glass formed when lava erupts onto the surface and cools rapidly. Its Japanese name is "kokuyoseki" (black曜石). The name "obsidian" comes from "Obsius," the name of its discoverer. Healing effects of obsidian: ◎ Cures indecisiveness ◎ Stabilizes emotions ◎ Breaks bad habits ◎ Gives the power to overcome adversity ◎ Enables quick action on things ◎ Enhances intellectual ability ◎ Increases concentration ◎ Wards off evil, protects against stalkers ◎ Cleanses consciousness A friend of mine carries obsidian to ward off ghosts, and there was a time when the obsidian cracked. Apparently, they were in a building that wasn't very good, and they said it was perfect for warding off evil. #cumi stone
