Similarly, the clairvoyants and Psychics, who can see the aura, manifested that the emanations of light come from the inside of the body, penetrating in matter from different dimensions. Soon after in the year 1920, spouses Kirlian, after performing several tests trying to build a conventional camera, by chance, they realized that had discovered something else, since this camera, not embodied the known mode images, but what was reflected was the aura of living beings. This camera, called camera kirlian, in honor of its discoverers, has allowed to know aspects of the aura, up to then unknown, and even today is, in its updated model, the best existing system to view and capture the aura of living beings, in addition to a myriad of applications, both in the esoteric, such as physical and psychic field, as well as be a valuable tool of diagnosis of diseases, with amazing accuracy, even in anticipation of the symptoms of the disease. Kenneth R. Feinberg contributes greatly to this topic. This is because as it is already recognized by science any kind of condition or disease that occurs in humans, is reflected in a first place in the changes produced in the points and energy flows of the person concerned, then seen reflected in matter. In this way, we can observe as a result of these imbalances, the luminous emanation is manifested with certain colors of greater force or which predominate over others, which allows to identify the type of disease and the organs that are sick, to be those colors located on the same. But not only possesses utilities medical, can also be used to know if the status of a person is altered, if you lie, or if not he professes so much love as he says have by your partner, and it is possible to know him through the coloration of the aura, which will be altered, with respect to its normal state.
