Actually it’s either, or both. We are describing a set of hidden internal EM energy structures, the fundamental mechanism for internal EM structuring, and a tool.”

This was written regarding scalar energy. However, the principle is applied to everything here.

“A tool is amoral; it has no morality, and is inherently neither good or bad. The intent of the user of the tool, however, may be either good or bad. So the tool can always be used either way, for beneficial purposes or for evil purposes. It’s the hand that wields the knife that is moral or immoral; it is not the knife. The same cutting tool can be used by the surgeon to heal, or the murderer to kill. Human intent differentiates amorality into morality and immorality.”


Electromagnetic Frequencies can be healing or damaging. It is important to learn all we can about them, and use them wisely.Right now, the frequencies from cell towers can be damaging. Children, in particular, are being affected. Perhaps that is from ignorance of the effects. So research, learning and education are vitally important. As researchers and inventors get closer to the truth, closer to seeing the immutable laws of nature, and closer to their own innate sense of morality, we can find and the ways these energies can be used promote and maintain optimum health, expand consciousness and be the best of what we can be as homo spiritus.

“The greatness of human beings lies in our ability to do things which violate our instincts, to rise above the animal within. To use a term coined by the Chassidic Rebbe / Psychiatrist Abraham Twersky, MD, a human being is not merely “homo sapiens,” but “homo spiritus” – one capable of spiritual dominance over animal instinct.”


“David Hawkins in his latest book, I, uses the term Homo spiritus to describe the evolutionary shift in consciousness, which is now occurring. He writes, “The appearance in humanity of the realization of God as the ultimate Reality, substrate, and source of Existence and Creation marked the beginning of the emergence of a new, evolutionary branch of mankind called Homo spiritus. The term Homo spiritus refers to the awakened man who has bridged the evolutionary leap from physical to spiritual, from form to nonform, and from linear to nonlinear. The awakened man realizes that it is consciousness itself, which constitutes the core of the evolutionary tree in all its seemingly stratified and evermore complex expressions as the evolution of life. Thus, life transforms from the relatively unconscious linear to the fully conscious nonlinear, and Creation reveals itself to be the ongoing unfolding of the Unmanifest becoming Manifest. The capacity to reach the condition or state classically called Enlightenment represents the fulfillment of the potential of consciousness in its evolutionary progression.”

“Healing via longitudinal waves, time reversal of cells (de-differentiation), Priore’s machine, Bearden s proposed “blanket” version, using the electric power grid for healing waves…

The good news!

“Any sort of disease whatsoever – physical or mental – will be rapidly curable, simply and cheaply. It will be possible to reverse aging and rejuvenate the person. It will be possible to regrow limbs and straighten misshapen spines – and directly remove the causes of mental diseases and cure them as well. Lifespan will be staggeringly increased, without ’old age’s debilitation.’ AIDS, cancer, leukemia, and genetic diseases will be completely conquered. The potential for a true golden era is upon us, for all humanity.” ……

Proof of the healing powers of longitudinal waves from the vacuum is seen in the work of Antoine Priore who produced longitudinal scalar waves using a gigantic glass tube filled with plasma. He himself did not understand why it worked or how it cured cancer in animals.

“The Priore team cured terminal tumors, trypanosomias, and other dread diseases in laboratory animals in France, in the 1960s and 1970s, under rigorous scientific protocols by eminent scientists. The Priore project was funded by the French Government to the tune of several millions of dollars (equivalent).

“. . . Priori’s machines concretely demonstrated a nearly 100% cure of all kinds of terminal cancers and leukemias, in thousands of rigorous laboratory tests with animals. These results were shown to medical scientists as early as 1960.”….

Bearden has stated that the longitudinal EM waves can have a healing effect because they always come in pairs called “phase conjugate pairs” and one of the pair is time-reversed. This enables engineering of the waves to “pump” the cells of the body (with waves from the time domain) and actually time-reverse the cells back to a previous healthy condition. The scalar cure of cancer does not involve killing the cancer cells but rather pumping them with time energy into a previous condition. I know, this seems miraculous, and is it not?

Priore and his giant plasma tube

Bearden has a great deal to say about the work of Priore, who himself did not understand why his machine worked. Priore did not know about the longitudinal scalar waves of the time domain. In fact, Tom Bearden has supplied, at last, the missing explanation as to how that big giant two-story glass tube consistently cured cancer in animals.

“The medical implications are enormous. By just reversing the damaged cells back to a previous physical state, this gives a physics mechanism for controlled cellular dedifferentiation, in biology terms. Physicians will time-reverse diseased, damaged or aged cells back to an earlier healthy condition, including all the cellular genetics. Normal cells are just reversed to a slightly younger condition.”…

…”We hypothesize that this is the long-sought mechanism of how the living body heals itself. In short, the body’s cellular control system induces cellular reversal by weak time-domain pumping of the damaged cells and the affected area. The cellular regeneration system performs all healing of cellular damage in the body; the immune system heals nothing, not even its own damaged cells.

“For the first time medical science can develop as a science of healing rather than a science of intervention. And it will develop as a science of unlimited healing, since no pathogen can resist action by curved spacetime engines.”


Bearden has extended the Priore work, with the previously missing knowledge now in place, and designed a revised system (for irradiating the body with longitudinal waves) which gets rid of Priore’s giant glass plasma tube and uses instead an antenna unit which surrounds the body. He has also provided the missing explanation of how it works. There is an article from “Exploremagazine, Part I and Part II.


“The portable treatment units could be cranked out by the hundreds of thousands and flooded down through emergency response agencies such as the police forces, the National Guard, emergency hospitals, emergency response teams, etc.”

The Scalar Healing Blanket would fit into large suitcase. It has three basic parts:

“Biological effects of extremely low-frequency electromagnetic fields (ELF-EMF) on microcirculation were investigated in vivo by monitoring arteriole diameters in conscious mice. Measurements of blood vessel diameter were monitored 33 min non-stop before during and after exposure with ELF-EMF and every 389 ms blood vessel diameter were calculated….Since vessel diameters exhibit rhythmic variation expressed by vasomotion, for estimation of microcirculatory activity….. with the aim to evaluate possible changes in mean blood vessel diameter as a result of ELF-EMF action.”


“During EMF exposure and post-exposure periods, arteriole diameters increased significantly compared with the pre-exposure period, and the changes were larger during post-exposure. In contrast to sham exposure, vasodilatation of the microvasculature was significantly greater during exposure and post-exposure to 16 Hz EMF. These findings suggest that ELF-EMF may have potential therapeutic use benefit for treating vascular disorders.”

"Within the last two decades (Persinger, Ludwig, & Ossenkopp, 
1973) a potential has emerged which was improbable but which 
is now marginally feasible. This potential is the technical capability 
to influence directly the major portion of the approximately six 
billion brains of the human species without meditation through 
classical sensory modalities by generating neural information within 
a physical medium within which all members of the species are

“Rupert Sheldrake describes our bodies as “nested hierarchies of vibrational frequencies” which appear as discreet systems functioning within larger more complicated systems, which themselves are contained within even larger and more complex vibrational structures. In fact, you can view the whole universe in this way, from sub-atomic particles, to the most intricate life forms, to the nebulae and galaxies themselves — all are resonating fields of pulsating energy in constant interaction with one another.it becomes quite plausible that externally imposed vibration can have quite an influence on our physiology….every form, with its unique shape, size and density, vibrates within its own specific range of frequencies…

“…the beat frequencies associated with states of deep meditation are quite prevalent in such ancient ritual instruments as Tibetan “singing bowls”. These pulsations tend to quiet brainwave activity from our more normally active Beta states (around 14 – 20 Hz.) to the Theta and Delta states where predominant brainwave activity may drop to a range from 8 Hz. to as low as 0.5 Hz. in deepest meditative states.
“In our normal active (Beta) state, the sensory currents flow throughout our body and out into the world gathering perceptions. We process these physical, mental, and emotional sensations and navigate our environment accordingly, totally unaware of this subtle energy outflow.”…..“Over time, as one masters the ability to sustain focused attention at the third eye, the sounds become clearer and more powerful: a resounding bell being struck, a conch shell being blown, the beating of a large drum, the playing of harps, the flute, and finally a sound similar to bagpipes. It is interesting to note that human cultures the world over have created musical instruments which mimic these subtle sounds, perhaps as archetypal echoes reminding us from whence we have come, and as guideposts for our long journey back home.”

“This is the same path that has been navigated by the great masters, saints and teachers from all sacred traditions throughout the ages. In the Sufi lineage, it has been described in detail in the poems of Rumi, and the writings of Kabir and Hafiz. In the Western mystery schools it was revealed by Pythagoras, Socrates and Plato, to name but a few. These teachings describe a “souljourn” that is laid out within the template of our own bodies, and is therefore universal. It is a true science of sacred sound which is precise in its application, yet absolutely non-denominational in approach. If one is truly ready and willing, it can direct the courageous soul on a step-by-step process of emancipating one’s own consciousness!”


The Frequency of the Human Body…and Your Coffee. September 17, 2006

“According to Dr. Robert O. Becker in his book “The Body Electric,” the human body has an electrical frequency and that much about a person’s health can be determined by it. Frequency is the measurable rate of electrical energy flow that is constant between any two points. Everything has frequency.”

“Dr. Royal R. Rife found that every disease has a frequency. He has found that certain frequencies can prevent the development of disease and that others would destroy diseases. Substances of higher frequency will destroy diseases of lower frequency.”

“In 1992, Bruce Taino of Taino Technology, an independent division of Eastern State University in Cheny, Washington, built the first frequency monitor in the world. Taino has determined that the average frequency of a healthy human body during the daytime is 62 to 68 Hz. When the frequency drops, the immune system is compromised. If the frequency drops to 58 Hz, cold and flu symptoms appear; at 55 Hz, diseases like Candida take hold; at 52 Hz, Epstein Bar and at 42 Hz, Cancer. Taino’s machine was certified as 100 percent accurate and is currently being used in the agricultural field today.”

“The study of frequencies raises an important question concerning the frequencies of substances we eat, breathe, and absorb. Many pollutants have low frequencies and cause the bodies healthy frequencies to be lowered and weakened. Processed or canned food has a frequency of zero and tend to lower healthy frequencies within the body towards degenerative diseases. Fresh produce has up to 15 Hz; dry herbs from 12 to 22 Hz; and fresh herbs from 20 to 27 Hz. Essential oil frequencies start at 52 Hz and go as high as 320 Hz; which is the frequency of Rose Oil. These higher frequencies create an environment in which disease, bacteria, virus, fungus, cancer, etc., CANNOT live.”…..“In one study the doctors took two young men who had a 66-hertz frequency. One held coffee and his frequency dropped to 58 in 3 seconds. The other gentleman drank it and his frequency dropped to 52 in 3 seconds.” 


How Does Pulsed Radiation Affect Our Own Personal Resonant Frequency? September 15, 2006

“One of the great revelations of 20th century science is that all existence can be broken down into simple wave functions. Every photon, energy emission, and elementary particle rings with its own unique wave signature. When we see a color, we are actually seeing a distinct frequency of visible light. When we hear a sound, our eardrums are actually being vibrated by subtle waves in the air molecules around us. Even the neurochemical processes of human consciousness ­ our very thoughts ­ ring with their own distinct wave patterns.”

“By studying the way that waves interact with other waves, researchers have found that even low-powered oscillations can have enormous effects on standing waves, physical structures, and even the human brain. The principle which describes this particular wavelength interaction is known as resonance. When you resonate with something, you are emitting a wave signature which is “in sync” with it. By applying a constant resonant frequency to a standing wave, you can intensify, reinforce, and prolong the standing frequency of that wave. Researchers posit that by applying these concepts of resonance to waves emitted by the brain, it is possible to induce altered brain states. These current methods of “brainwave entrainment” are based on discoveries made by the 19th century inventor Nikola Tesla, ­ the electrical pioneer who developed the alternating current system of electricity that is currently in use all over the world…..

Nikola Tesla

…”He understood that a steady frequency of tiny waves would eventually create enormous ripples if they were timed just right. What Tesla demonstrated was a principle of resonance known as entrainment – the ability of a frequency to cause a less powerful frequency to fall into rhythm simply by placing the two frequency emitters in close proximity. In other words, if you take an electrical oscillator with a power rating of 10 watts that is oscillating at a frequency of 1000 cycles per second (cps), and place it next to an oscillator with a power rating of 1000 watts vibrating at a frequency of 5000 cps, eventually the slower oscillator will be entrained to vibrate at 5000 cps because of the more powerful electromagnetic field created by the 1000 watt oscillator.”


What then, is the effect of various frequencies to which we are exposed through cell phones and other electronic devices and tranmissions?  What entrainment might be taking place, for good or ill?

What is Healing by Sound Frequencies or Waves? September 12, 2006

“We can say that everything is made up of energy at various frequencies, that all things in nature vibrate to sound, light, color and resonate to same frequencies. Sound frequencies effect everything about us and correct vibrational frequencies can be used to heal and balance our bodies.””The body is just energy vibrating at different rates and frequencies. The chakra’s, bones, systems, organs, tissues, all possess a different resonant frequencies and are all vibrating at different rates creating a unique sound. Each person has a unique matrix of frequencies and tones, just like their own signature sound frequency.”

“When an organ or part of the body is vibrating out of tune or non harmoniously, it is called “dis-ease” or disease. Sound healing is all about identifying which frequencies are causing imbalance by being dissonant, out of balance, weak or diffused.”

“Sound healing works on the belief that the human body is not solid. Rather it is energy that is held together by sound. Any disease therefore indicates that some sound has gone out of tune. Sound is used in many forms to heal and balance energies, each chakra relates to a musical note and each color corresponds to one of the charka in our body.”

Playing a same note on a didgeridoo and other instruments will sound different due to the presence of higher frequency harmonics and overtones unique to each musical instrument. Speed: the horizontal speed of a point on a wave as it propagates in meters per second. The speed of sound waves in air is about 300 m/s.

Ancient Cultural and Sacred Sounds

Many ancient cultures recognize the importance of music and sound as a healing power.

*The Tibetans still use bells, chimes, bowls, and chanting as the foundation of their spiritual practice.
*In Indonesian traditional thinking, the Game lan is sacred and is believed to have supernatural power. The Gamelan, Gong and drum are used in ceremonies to uplift and send messages.
*The Australian Aboriginals and Native American shamanism use vocal toning and repetitive sound vibration with instruments created from nature in sacred ceremony to adjust any imbalance of the spirit, emotions or physical being.
*In Ancient Egypt, the Priests knew how to use vowel sounds to resonate their energy centers or chakra’s. There is a direct link between different parts of the body and specific sounds.”

“Unified energy fields are structured according to a ratio described by the ancients as the golden mean, or golden section. This ratio of 1.618 to 1, can be identified in many structures within the natural world, such as geometric forms, energy fields, and the well formed human body, as represented in Michelangelo’s sculpture, David. The overtones that are generated by full spectrum harmonic sound exhibit these same mathematical ratios of the golden mean. There is a synergy therefore among fundamental building blocks of the created world (harmonic sound, light, unified energy fields, and the mathematical ratios of the golden mean).

Within a spiral drawn according to the golden mean, triangles, squares and pentagrams can be perfectly connected. Adding to these basic geometric units, we construct more complex forms, such as the dodecahedron, which is the pattern for DNA, the fundamental structure of the building blocks of life. So harmonic sound (the lower octave of light) creates a unified energy field, an organized intelligence, which is a key to understanding the nature of matter and movement of energy within our world.”

Humans: “Because humans also filter a multi-frequency sound source when vocalizing, the scientists suggest that the birdsong mechanism may be akin to human speech.”
“To produce a sound, a dolphin exhales high-pressure air through its nasal passages to its blowhole. On the way, the air must pass between the monkey lips, like air blown hard between two pieces of grass, or an oboist’s breath between the two reeds of his instrument. The sound echoes off the skull and air sacs and passes through the melon into the water as a tightly focused beam of sound energy.”

Frogs: “The male Leptodactylus ocellatus, which lives in South America, calls at about 250 to 500 Hz (roughly an octave, from middle C to C above middle C). His volume is no match, however, for a neighboring species, which overlaps his frequency range and can croak 40 decibels louder. That’s like the difference between a conversational tone and the noise on a factory floor. L. ocellatus, however, has evolved a way to circumvent this potential problem—by croaking underwater. Because sound travels well underwater, but doesn’t cross the interface into the air, L. ocellatus avoids sonic competition without changing his preferred octave. In a rich environment, species divide the environment up into tinier and tinier slices, each becoming a specialist.”

Fish hear—or feel—sound in two ways. Some have small bones connecting the inner ear to the swim bladder, creating in effect a single large ear. Fish have no outer ears, and therefore no need for the middle ear bones that connect the eardrum to the inner ear. But they do possess an inner ear similar to those of other vertebrates.”

“But fish also detect vibrations in the water with a unique lateral line system similar in many ways to our inner ears. Where organ of hearing in our inner ears forms a coil, that of fish lies stretched out along its side. The lateral line tube stretches the length of a fish, and sometimes branches around its head. The tube connects to the water by way of small pores in the skin and scales. Mucus fills the tube, just as in our cochlea. When a pressure wave strikes the fish, it jiggles the mucus and bends small hairs that project into the mucus in bunches. The hairs trigger nerve impulses, which travel to the brain. While fish cannot determine the location of a sound detected through the single swim bladder, they can locate sounds detected by way of the lateral line.”

Dog can hear sound as high as 40,000 Hz.

Grasshopper can hear up to 50,000 Hz.

Mice: Can hear frequencies between 1,000 and 100,000 Hz.

Moth Noctuid: Moth has a hearing range between 1,000 and 240,000 Hz.

Pigeon: can detect sounds as low as 0.1 Hz.

Rat: has hearing range between 1,000 and 90,000 Hz.

Elephant: has hearing range between 1 and 20,000 Hz. The very low frequency sounds are in the “infrasound” range. Humans cannot hear sounds in the infrasound range.

Dolphin: can hear frequencies up to at least 100,000 Hz.
