"Rife claimed to have documented a “Mortal Oscillatory Rate” for various pathogenic organisms, and to be able to destroy the organisms by vibrating them at this particular rate."

"when the proper mortal oscillatory rate (MOR) was reached, many lethal organisms such as those of tuberculosis, typhoid, leprosy, hoof-and-mouth disease, and others appeared to disintegrate or "blow up" in the field of his microscope."

"Dr. Rife discovered that every virus, bacterium, parasite and pathogen is sensitive to a specific frequency of sound and can be destroyed by intensifying that frequency until it literally explodes, much like an intense musical note that can shatter a wine glass."

"To attain these astounding results, a long and tedious process is started to determine the precise setting of the frequency instrument that is the mortal oscillatory rate of this virus. When the setting is found, it is repeated 10 consecutive times after the frequency instrument has been placed back to the same setting before a specific frequency is recorded."

"Rife named this intensified frequency the mortal oscillatory rate, or “MOR”, and isolated the MOR frequencies of 52 viruses, including typhoid, tuberculosis, and cancer."

"Rife called this frequency ‘the mortal oscillatory rate,’ or ‘MOR’, and it did no harm whatsoever to the surrounding tissues."

"Rife went on to discover and list the frequencies MOR (mortal oscillatory rate) for many different pathogens. Because he carefully kept a record of what he had learned, others too were able to benefit from his experiments"
