Excerpt taken from Scott Cunningham’s, Earth Power
Light a candle. Keep it lit for several hours, with no drafts nearby. Ask a yes or no question. Now sit quietly and watch the candle.
If the right side burns faster than the left, the answer is yes. If the reverse, the answer is no.
When burning a candle to determine future influences, the right signifies good fortune. However, if the left side burns more quickly than the right, prospects are ill.
