Everything vibrates. Every atom in the universe has a specific vibratory or periodic motion. Each periodic motion has a frequency (the number of oscillations per second) that can be measured in Hertz. Every element in the Periodic Table has a specific vibratory frequency. We use enzymes to break down molecular components. Each of these enzymes has a unique crystalline form with a specific vibratory frequency.
However, different types of frequencies can have a chaotic or a harmonizing effect on our own systems. When something vibrates at many dissonant frequencies, it produces "chaotic or incoherent frequencies." (David Stewart, The Chemistry of Essential Oils Made Simple).
All of the electrical devices in your home - lamps, television, radio, phone, and microwave - emit electromagnetic vibrational frequencies. But they use AC (alternating current) electrical frequencies that are incoherent and chaotic. Their effect is to fracture the human electrical field.
The human body vibrating within its normal vibratory range between 62 and 68 MHz is considered in a state of health. But energy disturbances in the subtle bodies will actually precede the appearance of disease and illness in the physical body.
