Crystal Ball Gazing

Light one or two candles in a darkened, quiet room. You can hold the crystal ball or place it on a stand, but it should have a blue or black velvet cloth underneath it. Make sure that there are no reflections from anything showing in the ball. You can also burn incense if you wish. 

Before beginning, center yourself. Gaze into the ball, but do not stare. Try not to blink too much. While you are gazing, deeply breathe in and out. You will feel a sense of limitless time. Enjoy the peacefulness and simply gaze. Do this for at least 15 minutes, increasing your time by five minutes per session. 

Usually around the second or third session, you will notice a small cloudy glow in the center of the crystal. This is your focusing area where your visions will appear. Some of you may get a vision on your first try, while others may have to attempt it several times before seeing something. There are different forms that visions come in. You can get actual visions of places and people, or you can get symbolic pictures. Another form that visions come in is color cloud. Although no one has been successful in identifying what each color cloud means, the following has been pretty accurate for a lot of gazers: 

Blue clouds symbolize success of career or business

Gold clouds symbolize prosperity, steady cash flow, and renewed romance to come 

Gray/Dark gray symbolize ill fortune

Black clouds symbolize some seriously bad stuff coming one's way

Green clouds symbolize health, happiness of the heart

Orange clouds symbolize hidden aggression and anger, troubled emotions

Red clouds symbolize danger to come. This person must watch themselves

Silver clouds symbolize troublesome times ahead followed by goodness

White clouds symbolize very good fortune to come

Yellow clouds symbolize upcoming obstacles
