V. V. Uvarov "Aura"

An example of the method for obtaining the vibrational spectrum of the aura of a fiery body can serve as a well-known method of Dr. Walter j. The Kilner, electroterapia of the hospital of St. Thomas in London, who lived in the last century.
For that reason this method was written by Helena Roerich*:
"I have a book Kilner "The Human Atmosphere (The Aura)" ... Mr. Kilaru managed with a specific chemical composition applied to the glass through which he looks at the test subject, identify the aura"...
Let us ask ourselves: why is the observation of the aura by the method of Dr. Kilner affect vision? The answer is simple. Dr. killer the used substance with a large refractive index as a kind of filter, through which only the light flux cut out only the ultraviolet part of the bearing vibration spectrum of the aura.
Ultraviolet radiation vibration spectrum falling on the retina of the eye, using the cells of the retina is dissected into its component frequencies and thus creates an image of the aura. If the selected vibration spectrum to send on the retina, and diffraction grating or other device that can expand the UV range, we will receive the required auric spectrum.
