It is best to find a quiet place to scry, so that you can hear your thoughts without distractions and concentrate on the objects you see. Make yourself comfortable. You can scry alone or with another person to talk to. As you prepare to scry, be sure that your vantage point for viewing the object is at good eye level. Remember that you will turn the object many times to see different things within it.
Crystal are life forms and have a lot to say and share, they are communication devices.
They send and receive signals. You just have to learn to 'tune in' to their channel - listen with your thoughts and look a the images that apeear on the screen behind your eyes. Older crystals will have more messages as they have experienced more frequencies in their time on the Earth plane and stored more information. Many crystals are record keepers, especially those from ancient civilizations, such as Atlantis. Crystal skulls, made from very old crystals, are example of ancient crystals.
