Watch the graph line
in the device, try to remember it in your mind.
Now Imagine This is the graph line of your thought level, and the
middle line is where your quiet zone is (No mind area), a place with
no thoughts, total silence.
As you can see (and feel) most of the time there is some thought
activity going on, with peaks of intensity which are the upper and
lower points.
Now close your eyes, imagine the graph in your mind, and watch the
movement of the graph following your thoughts and their intensity.
Look at the peaks and how they change according to your thought
level. The graph is following your thoughts.
Now Imagine the "noise" in the graph decreasing, meaning the line
becomes a little flatter. You can Imagine a "switch" like a radios
volume button, and turn it a little until the noise in the graph is
reduced somewhat. Slowly the thoughts in your head are slowing down,
becoming less intense, as the line is flattening. After 2-3 minutes
try gently to flatten the line (in your imagination) until it
flattens to the zero. As the line is flattening, the head becomes
more and more quiet, empty from thought.
Stay with this pleasant feeling for a few moments...

On the right is the "Peace Maker", it is an
"advanced" device to create silence...
