There is another school which believes that all magical ceremonies should consist of an act together with a rhyming spell. That is, you must show the Powers what to do, then bind them with a rhyme.

Now if anyone in the last two hundred years had tried to make up a rite they would have used one of these methods or something resembling them. The English witches’ method is entirely different. They believe the power is within themselves and exudes from their bodies. It would be dissipated were it not for the circle cast, as previously remarked, to keep the power in, and not, as magicians usually use it, to keep the spirits out. A witch can and does move freely in and out of the circle when she wishes.
