It is confusing at first. I that you just keep zapping the regular way. And read Dr. Clark's books over and over and then you will start unraveling the puzzles. In the syncrometer book, there are little experiments one can do. With each experiment, great big lessons are taught. I even heard someone said that all the books are online now.
It will become easier to understand. Maryellen is very good at using the zapper. She has been doing it a long time now and has had great results.
