A free-standing candle runs and melts a lot while burning
This gives you an opportunity to observe the flow of wax for signs. Quickly melting wax shows there is a good deal of positivity available. If one side burns quicker than the other, a balance can sometimes be achieved by turning the candle round and it is useful to note how many times you do this, since this can indicate the number of adjustments the person may have to make to ensure success. Other people prefer to let nature take its course and to watch the wax run for signs, without interfering in its movements.
