It is very important to pay attention to the experience of energy
in your body as you practice Brain Wave Vibration. Energy
is the real stuff of life, and it is through energy that oneness reveals
itself. If you can quiet your mind sufficiently, you will sense
this in your body as a subtle but consistent vibration.

If you allow this sensation to expand, you will not sense any
end to this energy and you will glimpse the infinite nature of the
universe. This greater cosmic energy I call Chun-ji-ki-un, which
literally translates as “the circulation of heaven and earth energy.”
To connect to this energy is to connect to the ultimate energy
pulsing through all of existence—what some may call the Source
and others call God.

There is a part of your brain that exists to connect to this energy.
You can conceptualize it as a radio receiver picking up invisible
messages from the cosmos. When your brain waves are
agitated, it is like static interrupting the signal. Please use Brain
Wave Vibration as a way to clear out the static and tune in to the
greater peace and serenity of the cosmos.
