[Part 1] As we delve into the medical aspect of things (whether you realize it or not, we are climbing a ladder here, being introduced to new [to us] aspects of reality in a gradual and structured way):
Everything is about vibration. Not in the woo-woo way we've been conditioned to think of it, but vibrating energy. Think "microwave oven." It resonates the water molecule. Put a surge of electromagnetic energy into a water molecule and it's going to move. Vibrate. It moves from A to B, then back to A. [This isn't really how it works but it makes the point.] Each movement takes a certain amount of time. Feed in the EM energy at that exact frequency (timing) and it's like pushing a kid on a swing: if your timing is just right, you push forward when the kid is moving forward anyway, and the kid goes higher and higher, eventually wrapping around the bar holding the swing. Everything is about timing. Apply force, in a specific direction, to something at the exact instant it was moving in that direction anyway and the energy just builds and builds. Push the kid on the swing at the wrong time and you either never make contact or you resist the backward motion. Everything is timing.
This is resonance. Every molecule, every atom, every object has a fixed (more or less) frequency it wants to vibrate at. Apply EM energy at that frequency and the molecules, atoms, etc. will excite more and more and more until they can't hold the energy anymore. At which point something about them changes. The swing wraps around the bar and changes the whole equation. The potato in the microwave starts on fire (so much for lunch.) Or, for our purposes, the cancer cell or evil virus or whatever shatters (cells have their own resonant frequency too). The most common example of using resonance to destroy something is the singer and the wine glass. Same principle: feeding in energy at an object’s resonant frequency.
In order for this to work, you have to exceed the object’s threshold for holding its structural integrity. [I know, too much Star Trek.] You have to build up more energy than it can handle.
That’s how Royal Rife was curing cancer in the 1930’s. Part 2 coming soon to a theater near you.
