A crystal meditation is a meditation with your crystal.....very self explanatory. (this is a branch of crystal ball gazing)
Crystal meditation is good for the chakras, good for relaxation and a great way to start forming a relationship with your crystal.
(Good for getting to know a new pendulum)
Hold your crystal in your hand (this has nothing to do with energy manipulation so any hand is good) And gaze at your crystal, look at every perfection, every imperfection, notice how it feels in your hands, notice it's energy ,how does it make you feel?.
This is also a branch of crystal ball gazing, usually trying to look for patterns, words or just plain scrying.
Blessed be, and have fun crystal meditating :)
