“At the heart of each of us, whatever our imperfections, there exists a silent pulse of perfect rhythm, made up of wave forms and resonances, which is absolutely individual and unique, and yet which connects us to everything in the universe.” — George Leonard, Silent Pulse 
Mantra is thought of as a beneficial meditative practice — empowered by faith, intention and concentration. Yet, there is a significant body of evidence that mantras, regardless of concentration or faith, are beneficial to health and surroundings. In other words, they may have influence over mind — and even environment (for example growth of plants) — even if the recipient of the sound has no faith in its efficacy. Expectant mothers play mantras for unborn babies. Caregivers chant mantras for pets. Neither babies nor pets have faith, but many swear by the effectiveness of mantra. Faith certainly empowers mantra further, as does intention, but some research seems to indicate benefit specifically from the sound and frequency.

Some Buddhist Teachers Recommend Mantra Even Where There’s No Faith
The notion that the beneficiaries of mantra do not require faith is also supported in Buddhist thinking as well. For example, Venerable Zasep Rinpoche recommends chanting mantras around your pets for their benefit. Clearly, they don’t have faith or concentration on the mantra, but the mantra seems to have effect anyway. Two weeks ago, Zasep Rinpoche recommended I chant Hayagriva mantra around my sick, aging horse who was lame. Within two days she was up on her feet and actually trotting around. The previous year, I helped support aging relatives (non Buddhist) and a cat — in both cases with Medicine Buddha mantra. These were not miracles, but they were supportive and transformative.
Likewise, Lobsang Dhargey, resident teacher at the Tibetan Buddhist Centre in Redding advises “recite mantras and pray for animals.” Lama Zopa Rinpoche strongly advises Medicine Buddha Mantra for sick or dying animals, spoken near their ear.

Medical Treatment: Nurses and Doctors Recommend Mantra for Some Conditions
Even if the patient or person has no knowledge or faith in mantras, the Annual Review of Nursing Research (2014), suggested “Mantra repetition is a simple, quick, portable and private complementary practice that may be used as an adjunct to current treatments for PTSD.”  In the Corsini Encyclopedia of Psychology and Behavioral Science, mantra identified research that proved the physiological benefits of mantra repetition: “lowered levels of tension; slower heart rate, decreased blood pressure, lower oxygen consumption, and increased alpha wave production. The benefits experienced in 20 minutes of meditation exceed those of deep sleep, thus indicating the regenerative power of meditation and saving of wear and tear on the body.” 
The Physics of Sound: A Cosmos of Rhythms
“The great rhythms of the cosmos are also revealed through modern physics,” writes Thomas Ashley Farrand in his book Healing Sounds.
In a near-Buddhist-like statement (particularly in its reference to emptiness), George Leonard writes in The Silent Pulse, about the vastness of space that composes what we call matter: “We can see the fully crystalline structure of muscle fiber, waving like wheat in the wind, pulsing many trillions of times a second… As we move closer to the nucleus, it begins to dissolve. It too is nothing more than an oscillating field [that] upon our approach dissolves into pure rhythm. Of what is the body made? It is made of emptiness and rhythm.” 
Synchronicity of Self-Created Sound
“It’s also been found that self created sounds such as chanting will cause the left and right hemispheres of the brain to synchronize,” said Jonathon Goldman, author of The 7 Secrets of Sound Healing. “Such chanting will also help oxygenate the brain, reduce our heart rate, blood pressure and assist in creating calm brainwave activity. In addition, listening to certain chants has great beneficial effects.” 
References to mantra’s benefits are common in various psychiatry and medical projects, papers and journals. In one project, they concluded through research that OM chanting calmed the stressed mind.  In yet another, they concluded that the Gayatri Mantra helped with tinnitus, Alzheimer’s and improving motor skills in Parkisonism. 
Change Molecular Structure? Can Sound Really Do That?
“There is no question that sound can alter molecular structure,” Jonathon Goldman explains “In the 1960’s, a medical doctor named Hans Jenny conducted experiments that showed that sound was able to actually create form in various substances such as plastics, plastes, liquids and water. He would place these substances—powders, etc. on a steel plate and then using a crystal oscillator, vibrate these plates with sound. The various substances took on the most organic looking shapes—they look like microscopic organisms or underwater life. Quite astounding.” 
Putting aside molecular effects, the entire field of Sonochemistry is concerned with “is concerned with understanding the effect of ultrasound in forming accoustic cavitation in liquids, resulting in the initiation or enhancement of the chemical activity in the solution.”  For example, this method can be used to destroy pollutants in water, or even to enhance cleaning (ultransonic cleaning). Sound profoundly effects all liquids. This lends some credence to the notion that sound also effects humans, animals and plants — which are mostly water. This is not at the molecular level, but a result of cavitation. “The chemical effects of ultrasound do not come from direct interaction with molecular species. Instead, sonochemistry and sonoluminescense arises from acoustic cavitation.” 
The simplest and most effective mantra for daily chanting is the “Compassion Mantra” of Avalokiteshvara:

Why Speech and Mantra Can Physically and Mentally Change Our Lives
Speech and language consume significant portions of our brain. It is reasonable to assume — and many Neuroscientists make this point — that sound and language influence the majority of aspects of our lives. In fact, Neuroscientist Mark Changizi, in his intriguing book How Language and Music Mimicked Nature and Transformed Ape into Man, hypothesizes that when we hear certain sounds we tangibly experience those events — for example, a scream brings instant feelings of tension and fear.  Critiquing the book, The Scientist magazine wrote that Changizi demonstrates a “…simple but striking premise to show how language and music…harness our brains.”
When we read a novel, we ourselves become a part of that story. Language and speech has that kind of power. Hearing the sound of a coyote on a lonely, dark night can make us feel irrational fear. The sound of a car crash triggers adrenalin in our bodies. The purr of a cat soothes and relaxes us. The laugh of a baby makes us smile. Hate speech inspires hate. Kind words generate compassion. It is reasonable to propose — and some cognitive scientists have — that mantra also has physical and emotional effects on our body that can even influence our health.
Transformative Energy from Sound
“Mantra meditation is not only something one practices, but a radical re-envisioning of ourselves, our lives and our ability to create the future we desire,” writes Thomas Ashley-Farrand in his book Mantra Meditation.  He adds, provocatively, “Mantra meditation is not magic, but the results can be magical.”
For example, the effect of mantra on growth of crops, for example, is widely reported and backed by research from the China Agricultural University. We reported on this in Buddha Weekly: “Buddhist Mantras Help Crops Grow — Increase Output by Fifteen Percent; Studies Reveal the Power of Mantras to Help Plants — People.” >>
In this reported news story, farmers in Fujian province increased crop yield and grain size by placing loud speakers in the fields playing repetitive Buddhist mantras. Nearby crops, out of reach of the sound mantras, “struggled with pests and suffered much reduced yield.” The researchers concluded, ” Although it’s well-established that some types of music do improve plant growth, normally assumed to be a sound-wave stimulation, mantras are particularly efficacious.”
Stress reduction and healing benefits of meditation are well accepted benefits of mantra. Putting aside faith and spiritual reasons, how is it possible, that a mantra can transform energy? Ashley Farrand proposes: “Repeating any sound produces an actual physical vibration. Nowhere is this idea truer than in Sanskrit mantra. When chanted out loud or silently, mantras create a single, powerful vibration… Over time, the mantra process begins to override and absorb all the smaller vibrations, which eventually become subsumed within the mantra.
Effect of Mantras on Human Beings — US National Library of Medicine
The effect of mantra on plants, living beings and humans is well documented and supported by research. The US National Library of Medicine has a notable abstract titled, “Effect of Mantras on Human Beings and Plants” in which: “The author during his various experiments on plants found that these from the stage of seedling to the maturity are effected by certain types of sound waves, especially the Mantras. This study reveals that the plants have shown a positive response to this type of particular sound waves regarding the growth. their efficacy in curing the diseases etc.” 
In part, some researchers assume this benefit to be sound frequency’s effect on water. The human body, plants, and animals are mostly water. Researcher Maseru Emoto published findings in a peer reviewed journal (Journal of Scientific Exploration) containing results of experiments on water. He photographically demonstrated the effect of mantras and sound on water with striking results. Ice crystals in water exposed to negative sounds or thoughts created predictable and negative formations, while water exposed to mantra, prayer or positive thoughts rendered beautiful and striking images. While scientists are divided on support for hs work, in part due to insufficient controls, no one disputed the general conclusion that sound can negatively or positively impact humans and plants — beings made up mostly of water. 
Sankrit’s Unique Sound Vibration
Sanskrit language in particular has been demonstrated to be more predictably impactful on body and mind. Most mantras are Sanskrit. This may be due to the ancient roots of Sanskrit, the mother of all languages (most modern languages evolved from Sanskrit (with the exception of indigenous languages of America, Africa and Australia).  In part the impact of ancient Sanskrit mantras on our unconscious minds, as suggested by Carl Gustav Jung. Sanskrit is also very rhythmic and, to some extent, mimics nature’s sounds — which have been proven in numerous studies to have a profound impact on our minds. (For example, the call of a loon, or the howl of a wolf evoke specific emotions in humans — primitive memories stored in our subconscious mind.)
“The gist of what they convey is that the universe at the physical and subtle level is composed of fifty vibrations,” writes Thomas Ashley Farrand in Mantra Meditation. “Collectively these vibrations are called the Matrika — the Mother… the spanda (vibrations) that have constucted the universe we inhabit.” Putting aside the spiritual thrust of that statement, it seems clear that Sanskrit contains within it, representative frequencies that can interact with our bodies and minds.
