It is a great stone for understanding and communicating with Spirit. It can be used to open one’s third eye and develop the psychic channel to hear one’s guides and teachers. It does not create the communication between the worlds rather it enhances and enlarges the communication channels that have previously been established. Used in a similar way as Lapis Lazuli, this stone develops the clarity of “hearing” into the other realms. And, as with Lapis, it has a very profound ability to protect the seer during channeling. It acts as a shield for the protection of the physical body from unwanted outside sources that might be lurking.
