Instructions on using your Crystal Ball below:
In a darkened room, sit quietly with the crystal in front of you. Allow for a low light source, so that the crystal is somewhat 'back lit" yet the rest of the room should remain dark. A candle works well be sure to follow safety rules when working with an open burning flame. The colour of the candle should be something that reflects Higher Purpose like Purple for Higher self, White for God/dess and Soul purity or orange for attraction (but be sure you say aloud that you wish to only attract positive energies or you could get any energy just floating by, I caution you on using orange if you are only beginning).
Next close your eyes, concentrate and ground yourself. Allow your third eye to activate and open. The use of Lemuria Oil tm is recommended here as it clears miss-aligned energies and protects the user (you) from negative energies trying to control the session and such. Place a dab on the 3rd eye area, located between your eyes and up just a smidge. Now be sure to set up a deep breathing pattern at your own rhythm. Allowing all the stress and negative energies to flow completely out of your body as you exhale, and positive energies to enter as you inhale. 'See' those positive energies replacing the exhaled negative energies, visualize all the positive energies completely centering your body and your intuition and focus becoming the central points of your thoughts.
Now open your eyes, and pick a spot on the ball you feel 'drawn' to. Focus on the spot and allow your eyes to fixate (like when your eyes get stuck looking at something but your mind (subconscious) is elsewhere) gazes past that spot. The crystal may begin to darken and smoke up. Allow this to happen, don't snap back to a conscious state, if you can help it. Don't worry if you do, fact is most of us do the first couple of times cause we are so excited its working. Snapping back to the conscious state makes you leave the trance like state and thus breaks the psychic connection. If this happens just re-enter the trance like state once more as best you can. Allow the ball to darken and smoke without breaking your trance like state. Do not try to make sense of the images you 'see, feel or hear' before you. Just go with the flow.
You may feel yourself start to tingle or vibrate, you may feel heat, cold or just detached from yourself. This is the crystal raising or lowering your vibratory level so that you may both be one in harmony and make the needed psychic connection.
Next you will begin to speak (a voice activated recorder is nice at this point) or write about what you see. You have entered the Astral plane at this point and may have some memory recall problems when you break the trance like state. This may occur until you have training and can work on both the Astral and physical plane at the same time, and not to lie to you, this could take years of concentration, practice, and many sessions. So don't give up and I advise using a tape recorder as it doesn't interfere with your focus, concentration, or gazing/scrying.
Finally when you feel you have seen enough, or the crystal's images fade out, allow your mind to return to the present (physical plane). Feel your vibratory rate change once again as the crystal separates from one to two separate beings again. Refocus your eyes; blink as you need and breathe deeply, as you ground yourself once more. Finally returning to the physical plane, with your mind cleared and energized. In Grounding yourself, a drink of water/juice and a snack can help, as you pull the earth's energies up into your body once more. Remember it takes practice so don't be upset if it doesn't work right away. Take your time, allow the crystal and your energies to match, it will work.
