In this regard, and as an illustrative example, we could see how babies and some young children, are sensitive to these manifestations, charged of luminosity and colorful, of persons who are to your around, as well as the rest of living beings, and that is not another thing that what will be called the aura. In the aura we can observe a wide range of colors, these ranging from white, violet, in the image and likeness of which can be seen in the arc Iris. This range of colours, will depend on as we have already mentioned above, the length of the wavelength or frequency of electromagnetic type, that control and processed the chakras, which also have the power to influence the hormonal glands secretions. When the chakras are operating correctly, a homogeneous luminosity is issued and soft tones, in the ultraviolet spectrum, which indicates a correct harmony of body and mind. On the contrary, physical and psychic disorders, they are responsible for the color change of the aura, turning to display dark colors or with stains, aspect that will indicate a deficiency at the physical level, as diseases degenerative type, cancer, infectious diseases, etc., as well as hormonal and psychological disorders.
At the spiritual level, it is interpreted as an indication of the degree of elevation that the individual possesses. Hence the great importance that the display of the aura has always had for the scholars and connoisseurs of the subject, where until recently only was accessible through the powers of clairvoyance. Scientific studies is from the 16th century that Paracelsus, defines it in a scientific way, and describing the aura as something that resembles a field of fire. Subsequently, are increasingly more scientific personalities who study the phenomenon, as well two centuries later is Franz A. Mesmer, who performs studies that lead him to present the theory of animal magnetism, described as an energy of electromagnetic type, which has the power to be able to be transmitted from one being to another, demonstrating excellent faculties for healing.
