"Shungite has a sheilding and purifying power that arises from its unique formation. It grounds spiritual energies into the body and anchors the body to the earth. It has a powerful link to ancient earth energies, restoring ley lines and the earth's meridians. It is highly supportive during metaphysical work of all kinds and is said to enhance prophecy."
