SCRYING is a fascinating practice in that it enables you to literally "see" the future (or present or past). Almost any reflective surface can be used for scrying (pronounced to rhyme with "crying"). A crystal ball and a gazing mirror are two of the best. Let's look at the crystal ball first. The crystal should be without flaw—no scratches on its surface or bubbles within (the new acrylic-plexiglass "crystals" work quite well, but scratch very easily). Rest the ball on a background of black. A black velvet cloth is ideal. This can, in turn, rest on a table in front of you or can cover your hand(s) if you wish to hold the crystal. This black background is to ensure that you see nothing around the ball to distract you as you gaze into it.
Initially you should work alone, in a room that is quiet and dark. Your temple, of course, is the ideal place. Have just one small light, preferably a candle. Place the light so that you do not see it reflected directly in the crystal. Burn a pleasant-smelling incense, since it will help you concentrate. Work in a consecrated circle, at least to begin with. Later, if you should want to use the crystal elsewhere, you can simply imagine yourself surrounded by, and completely encompassed in, white light; though even then I would strongly advise casting a small circle about yourself with your athame. Start by saying some protective prayer (such as the Seax-Wica Psalm), then ask the Lord and the Lady for their guidance and their protection.
Now sit and gaze into the crystal trying to keep your mind blank. This is not easy and will take some practice. Do not stare at the ball unblinking; this will just cause eyestrain! Gaze—blinking your eyes naturally, as necessary. Do not try to imagine anything in the ball. Just try to keep your mind blank. After a while (anywhere from two to ten minutes) it will seem that the ball is filling with white mist or smoke. It will gradually grow more and more dense until the ball seems full of it. Then, again gradually, the smoke will thin and fade, leaving behind a picture—almost like a miniature television picture. It might be in black-and-white but is more likely to be in color. It might be still or it might be moving. It might be from the past, present or future. Also, it is very likely to be a symbolic picture, requiring some interpretation—much like a dream.
Initially you have no great control over what you see. You must just take what comes. As you become more adept, you may meditate for afew moments before gazing on what you wish to see. Then, when you start to gaze, clear your mind and try to keep it blank. Most people seem capable of success at scrying. If you get nothing the first time you try, then try again the next night, and then the next. It may take a week or more before you get anything, but keep trying. Do not, however, try for more than about ten minutes or so at each attempt.
