Before we answer this question we should point out that Crystal healing is not a substitute for modern medical practices. We often hear stories about people getting so much benefit from crystal healing that they stop or alter what doctors tell them to do. We have histories best medical system and crystal healing should not replace or alter what doctors tell you to do. Crystal healing is a secondary complimentary procedure that should be run separately from scientific medical practices. Today we have histories best medical system ever. Running it parallel with ancient and future mystical technologies certainly wont hurt.
So does it work? Remember that more than a hundred years ago some scientists got roundly ridiculed when they suggested that some common rocks that they were studying would one day provide the world with energy. It was a bit of a silly concept. Today Uranium provides a large portion of the worlds energy. A similar scenario could well be true in the future after we discover more about how crystals affect us. We know that there are various types of energy and things like gravity, photons and neutrinos and other types of particles (Probably some that we haven’t yet discovered) that pass through everything on earth. These affect living organisms in ways that science don’t currently understand. The idea is that these particles are affected by different types of crystals as they pass through them. This is why each different crystal has different properties. The chemical structure affects particles and energy differently as it passes through them. And holding the stones as close to your body as possible absorbs this energy. Crystals in your house also affects the energy, air and ambience of the dynamics of the room. This is why certain crystals are placed in different areas of a home.
Many people get wonderful benefits of Crystal healing. But it affects people differently. Some people can feel different temperatures or energy when they place their hand over crystals or place crystals around certain points of their body (Especially if they sleep around them absorbing energy all night). It is often said that “Crystals choose you” rather than the other way around. Other people get major health benefits and more energy or clarity of the mind after using crystals a certain way. Many practitioners believe that their medical conditions improved after using crystals. Some people get no benefit at all. It is not known why some people benefit and others don’t. But surrounding oneself with pretty eye appealing crystals can only be relaxing and make for positive mental benefits.
