This can be understood on the physical level by the concept of ‘resonance’.
When we expose the body to sound frequencies similar to those that exist naturally in the substances and centers of energy in the body, the sound waves create a resonance in the bodily material and energy, and alter the fluctuation and motility of these materials.
If, for example, there is a blockage in the flow of blood in any particular part of the body – and we know what the energetic frequency of that part of the body is – we can use the sound that helps the flow of blood, thereby releasing the blockage.
This is a field which is being explored at the present time. We do not yet have all of the information about the specific effect of each frequency on each material in the body, but research in this field is making great strides.
From a physiological aspect, mechanical, physical and biochemical functions in the body have different types of materials and structures, and each of them resonates differently. The bones, for example, resonate with a strong movement, while the finger joints dim the passage of the sound frequencies.
The joints of the skull, the auditory canal, the structure of the eardrum and the entire ear are built to undergo change following exposure to sounds, as well as changing sound frequencies into electromagnetic vibration in other parts of the body. The change, which is electric in nature, creates a chain reaction of molecule and substance movement which branch out throughout the body.
