A rare form of Quartz crystal. These cystals must have inspired architects to create turreted castles and cathedrals. Watch out for the lightbrary Cathedrals. They are generally very translucent Cathedral crystals that also appear to have doorways. Cathedral Quartz crystals are named after their shape. They look like mini castles. Not to be confused with Amethyst Geodes; these have only just started to be referred to Cathedrals in the last few years, where the crystals like the ones shown have been referred to Cathedrals for many decades. Clear Cathedrals are referred to as Lightbrary Cathedrals. Lightbraries are said to house the Libraries of Light! These crystals have doorways in them, more often than not, in their castling definition. To travel into the crystal, just gaze into the doorway, you will see it open and your consciousness will be drawn into the crystal. From there you can travel into different chambers and receive information that you are ready for at that time. You can also travel in inner and outer space in complete safety within the crystal.
