Actually there are a couple of ways one can measure a vibratory frequency.Electrical currents run through every cell and tissue of the body. Where you get an electrical current you get a magnetic field. Electric fields are just charged particles. Please read, or look up, John Zimmerman of the Bio Electro Magnetics Institute.
I purchased a Raditech machine from Dulwich Health and have constant readings. A guy called Rolf Gordon does them for free. Also Dr. Stephen Lewis who is the founder of EMC2. I believe we live in a sea of energy and that means we are constant sustenance. I am often worried that healers don't always understand that. They think good intentions are enough. So many healers become sick because they don't know how to properly direct energy, nor how to avoid becoming anothers sustenance. Sadly, I see not so much energy exchanging, as I do energy bleeding. Healers become sick. So many healers, but sadly not many healed. Whoops, sorry, that's another subject for another time!
The higher your vibratory frequency, the higher your consciousness and the higher your physical immunity. Also as a kind of bonus, less remains hidden and the more you see.
All systems are regulated by invisible organizing fields. We now have ways of measuring these fields.
Please read the Sanctuary, or look it up on the web for more comprehensive explanations.
I became very interested in Stephen Lewis and his work very early on. He was a well known and very accomplished doctor to many celebs in Hollywood - who could afford the best. He made millions, became wealthy and famous, but was more interested in alternatives. He travelled to many places and did various studies in accupuncture and homeopathy. After studying Wilhelm Reich's work and testing his theories, Stephen took several years off to develop his machine. It took many thousands to eventually get it to
the stage where he could help the thousands that kept knocking at his door. I am on AIM myself. I have been on AIM for almost 5 years now.
Hope this helps.
Enjoy the energy ride!
