Deep relaxation isn't a luxury,
it's the foundation of true healing and a healthy life.
The Harmonic Egg® is a sanctuary for deep rest. Through a powerful blend of sound healing, color therapy, and the sacred geometry of its wooden structure, it opens the door to expanded consciousness. In this state of deep stillness, the body's innate ability to heal and restore is naturally activated.
Inside is where the magic happens
This natural frequency therapy helps bring the body into homeostasis by deeply calming the nervous system. A regulated nervous system is essential for lasting healing, recovery, and emotional well-being.
The benefits
Regulated nervous system
A calm nervous system is the key to healing. Only when the body feels safe can it repair, restore, and thrive.
Deep meditative state of relaxation
Deep relaxation creates the foundation for transformation — when the body feels safe and calm, true healing can begin.
Healing on a cellular level
Sound resonates through every cell in the body, activating deep cellular repair and healing from within.
How the Harmonic Egg® works:
Cellular healing through sound and light frequencies
The Harmonic Egg® promotes deep healing on a cellular level using a unique combination of resonant sound, color therapy, and light frequencies. These frequencies are naturally recognized and decoded by the body as healing vibrations, helping to restore balance and stimulate self-repair.
Our cells communicate through resonance, just like tuning into the right radio frequency, a clear signal supports harmony, while a distorted one disrupts communication. The Harmonic Egg® helps “retune” your body to its optimal frequency.
Scientific research shows that vibrational frequencies from sound and color enter the body via the nervous system, muscles, bones, and even through skin receptors, influencing our physical and energetic systems at the deepest levels.
Every cell, organ, and bone in the body vibrates at its own natural resonant frequency, creating a unique electromagnetic field and frequency pattern. Much like instruments in an orchestra, these individual frequencies harmonize to maintain balance and well-being. When one part of the body falls out of tune, it disrupts the entire system. Sound therapy, as used in the Harmonic Egg®, helps retune these frequencies; restoring harmony, cellular balance, and overall vibrational health.

Grateful clients
I've been to the Harmonic Egg at Ydwine in Eindhoven about four times now. Each time it is a special experience, each time in a different way. And every time I get a little better.
I've fallen on my head just too often in my life, which means that I'm dealing with cognitive complaints and my living environment has become extremely small due to overstimulation.
Since I've been in the egg a lot has changed, if not everything. My load capacity is much greater. Where I used to have to schedule a few additional days between appointments, my agenda is now fuller than ever. Driving takes much less energy. I've been to a concert a few times. The second concert was a guitar concert that turned out to last almost 4 hours! After a good night's sleep I just felt good again.
I have dared to book a week's holiday abroad for years. My problem solving skills have started to come back. I'm much brighter, I'm more cheerful and a nicer partner, if I do say so myself :).
I am incredibly grateful that the Harmonic Egg came my way. Because I never dreamed that I would recover so much again. And then an hour in the egg is also a wonderful, relaxing experience. What a gift. I am very grateful to Gail Lynn, the Eindhoven egg and of course Ydwine.

The Harmonic Egg was a very special experience for me in a beautiful, relaxing environment. Ydwine explains everything calmly in advance and adapts each session to what you want to achieve. I came out very 'zen' and relaxed and would love to come back. Highly recommended!

My Harmonic Egg experience in Eindhoven with Ydwine.
It is difficult to find the words when you don't know much about energy and frequencies, but I will try. When I try something new I go in with an open mind and a childlike curiosity and that is probably a good advise for anybody - no expectations, so you can receive. In the first few minutes I relaxed and almost immediately was taken on a journey and pictures appeared. I was blessed to meet someone and had a active conversation that was guiding me. Even though I went in for something totally different, I received exactly what I needed at that moment. The kindness and love I was able to feel is out of this world and I strongly believe that we are all protected and guided by something higher. When my session was over, it felt like I was only in there for minutes and my body felt very relaxed and light - almost like a total reset.
I will for sure go back and have another session. Ydwine is very intuitive and kind and her knowledge will ease your tension if you go in for the first time. Everybody can benefit, but the experience is very individual. Just have an open mind and be curious.
This is probably one of the future healing tool.
