Miracles at Bretforton – The Book

Mandara Cromwell with her book Miracles at Bretforton

Hello Friends of Cyma Technologies,

I am excited to announce my second book, Miracles at Bretforton, is about to be published soon!

For all of you who love the AMI devices, this book will provide great insight on how the early cymatic therapy became the Cymatherapy™ we use so effectively today. In it, I share many memories of my experiences during the history and development of sound therapy that have inspired me all along the way.

I want the Cyma Technologies community to be the first to enjoy reading about the miracles of my early studies with Dr. Peter Guy Manners at the Breforton Hall Clinic in the United Kingdom.

The release of this book marks my 25 years of producing sound instruments that utilize the frequencies I first learned about at Bretforton Hall. It is important to take a fond look at the past, while gazing confidently into the future, as we embark on the path to further sound discoveries. Another way we can celebrate the recent decades is by enjoying the knowledge of the visionaries that helped us make this progress…

For this reason, I am offering a special gift— Cymatics: The Art and Science of Making Sound Visible Video—to the first 100 people who pre-order “Miracles at Bretforton.”

Book Reviews

It really is time to focus on the prevention and wellness aspects of our health. The channels in the AMI devices can help us, both in times of health and health challenges. We need to believe in the body’s own healing abilities. Dr. Cromwell is helping us to see this is as a real possibility, with the healing power of sound. When we are in good resonance with our bodies, we can begin to discover what has led to dis-ease. Then we can determine what we really need to do to regain our health. I believe the AMI devices offer a bridge between traditional medicine and alternative choices which is important for the healing of humankind. Hearing the stories of early cymatic therapy was truly inspiring!

As a Cymatherapist who graduated from the AMI certification course at Cyma Technologies, I was so impressed with all the new knowledge offered me about my health during our studies. Reading Miracles at Bretforton helped me realize how much science really is behind the idea of frequency healing and how far we have come in its development over the last 25 years, thanks to Dr. Cromwell’s efforts. I am looking forward to learning more and more in the future.

I was so excited to read this book, as it outlines for us a proven and magnificent way we can use sound to heal. The human race is beginning to see the long-term negative effects of using pharmaceuticals as the only answer for our health challenges and diseases. Many people mistakenly think that all drugs are backed by solid scientific research. Dr. Cromwell has dedicated her life to continuing to make discoveries about the original healing frequencies she was given by Dr. Manners. This paves the way for achieving optimum health in concordance with the natural laws of our planet and our bodies.

I have been an AMI sound therapist for years. I can remember hearing about the work of Dr. Manners in conferences I have attended. Mandara has extended Dr. Manners’ reach all around the world and made his knowledge accessible to the average person. Through Mandara’s efforts, we can be responsible for our health and use the kind of healing that resonates with ourselves and our planet. Miracles at Bretforton is a powerful reminder of this.

Mandara’s stages of discovery throughout her time at Bretforton Hall are a reminder to us all of how much knowledge and wonder is available to us in this world. She held her spiritual studies close to her heart and integrated them with ancient knowledge, (and what many would call miracles), all found in a small clinic in the Cotswold, in the UK. The value of what she has brought to us may not be fully understood in this lifetime, but it is clearly a part of the medicine of the future.

Many people still don’t know about sound therapy—or their perception of it is may not be completely clear, due to something they have read on the internet. This book explains the early cymatic therapy and how it has developed into the Cymatherapy readily available to us today. I have used my AMI 750 for years and am so glad to have this new level of understanding available in Miracles at Breforton. It makes me see the benefit of the therapy and these modern day devices even more.

When I read Mandara’s first book, “Soundflower” I was taken by the level of spiritual awakening that was taking place during her scientific discoveries. Reading “Miracles at Bretforton,” I was impressed with the amount of knowledge she accumulated during her introduction to cymatic therapy. Amazingly, she has brought all of this to us in her AMI devices for the benefit of humankind. Thank you Mandara!

World changing discoveries are made when people follow their inner truth and then combine it with sources of knowledge. Mandara’s story proves that curiosity, joined with a visionary approach, leads to the solutions which can be found in the many gifts offered by our Universe.
Samuel in Duluth, GA
Many people are seeking alternative health methods these day. To read the story of the development of this form of sound therapy is helpful in many ways. Mandara’s journey proves that the world can be changed and made better by the choices of each person—especially when they are dedicated in their hearts to helping humanity.

About the Author

Mandara Cromwell is an entrepreneur, inventor, researcher and author. In 2001, she began her studies of the original cymatic therapy with British osteopath, Peter Guy Manners, and was awarded the Diplomat of Cymatic Bioenergetic Medicine, at Bretforton Hall Clinic in the UK. She later received her Doctorate of Cymatic Medicine through Medicina Alternativa in 2004. As CEO of Cyma Technologies in the US, she manufactures her own inventions—the AMI Acoustic Meridian Intelligence devices—for the therapeutic application of specific sound frequencies to the body. She has made it her life’s work to take Dr. Manners’ knowledge to greater heights through research, education and collaboration.

Since 2011, the AMI devices have been manufactured by Cyma Technologies in the US, to insure the preservation of the specific healing frequencies, the device design and concepts. Her company produces sound therapy instruments for the purposes of creating vibrant health, jobs of the future and new ways of thinking. Her mission is to change the face of healthcare in the US and the world, through acoustic frequencies combined with advanced sound technology. Dr. Cromwell coined the term “Cymatherapy” to distinguish between “cymatics—the study of wave phenomenon,” and the therapeutic application of specific sound frequencies to the body.

She holds a BA in Art History, which inspired her to seek studies in Eastern philosophy, through extended travels to India and China. This provided an opportunity for in-depth investigation of the ancient teachings of Ayurveda and Chinese medicine. This knowledge culminated in the innovation of the AMI Acoustic Meridian Intelligence devices and concept. The invention of her first device, the AMI 750, resulted in a nomination for the Thomas Edison Award in 2013 for Innovation in the fields of Science and Medicine. Successive inventions of the AMI 850 and AMI 500 devices have continued to provide new approaches in Cymatherapy for both private owners and healthcare professionals.

Mandara is the author of Soundflower: The Journey to Marry Science and Spirit, the story of how sound discoveries—both scientific and mystical—have influenced her personal journey, throughout her lifetime. She continues to research and develop the many applications of therapeutic sound, to include products using images of therapeutic sound frequencies made visible. Her innovation with the “Soundflower Experience,” created a new sound/visual meditation based on the images generated by the AMI device. They have become an extremely effective way to reduce stress, while cultivating vibrant health and longevity.

The 2026 release of her second book, Miracles at Bretforton, has encouraged many to look at sound therapy as a viable solution for a drug-free non-invasive approach to health—as well as an inspiration for healthcare professionals and healers to integrate Cymatherapy into their careers and plans for healing the world.

In 2005, she founded the International Sound Therapy Association (ISTA), a non-profit organization to increase the public’s awareness of the healing power of therapeutic sound, through conferences, educational courses and sharing the latest sound discoveries with visionaries in the field of vibrational medicine. She is a compelling speaker on the healing power of sound and how to access its many benefits through both ancient techniques and her own innovations.

With her many endeavors, she still finds time to enjoy the beauty of the natural world, the pleasures of home and her three grandchildren, with whom she hopes to share the wisdom of her many life experiences.

A Note from The Author

Writing Miracles at Bretforton involved sorting through countless memories of the early days. It conjured up many in-depth teacher/student sessions with Dr. Manners about cymatic therapy and its origins—but also the endearing moments of having simple conversations with him over tea about our expectations of life ahead and what we both believed.

When I was living through the initial days at Bretforton Hall, it all seemed so chaotic. There was much to learn, many people to meet and thousands of details to manifest this new solution for the world. My developing personal dream was that I could take cymatic therapy to the US and also into a new world of possibilities. From the beginning, it seemed to me that this form of sound therapy could be the answer for many. The more I learned, the more I was certain that it could alleviate suffering and provide an alternative for a world convinced there were no other solutions than pharmaceuticals.

I still marvel at all the “miracles” I experienced at Bretforton Hall, during my introduction to cymatic therapy—especially the technique of using trans-dermal application of sound to the body with an applicator. I had never seen this done before and I still remember the excitement I felt when watching Dr. Manners’ patients respond almost miraculously to it. I have often thought of sound therapy as an opportunity for people to re-discover their body’s own ability to heal. I invest time every day to learn more about what we can do with therapeutic sound for prevention of illness. This helps to paint a much brighter future for us all.

The body is an extraordinary creation that responds beautifully to the sounds contained in the AMI—Acoustic Meridian Intelligence devices,.

I have been shown that the correct sound to match your body’s “cellular conversation” can have positive, dramatic effects on its ability to heal. The meridian pathways, as taught in Chinese medicine, offered me the most perfect avenues for delivering the audible sound frequencies. Above all, the body’s innate intelligence partners with us, when we provide the correct communication.

Miracles at Bretforton is my second book, but probably not my last. The extraordinary experiences people have shared with me over the years will always be held in my heart. Their stories have inspired my work for more than twenty-five years. Finding the right path for healing and spiritual growth can sometimes be challenging. I believe the sound frequencies in the AMI devices can bring into harmony the multiple layers of being. With this new awareness, we can return to a place of bliss within ourselves and our world. I hope the stories in the book will inspire many to try Cymatherapy. My vision is of a world full of healthy vibrations, encircling the Earth and all of her children. In this way, pain and suffering will become our distant memories.

Enjoy with me the many Miracles at Breforton,
