Persons with a lot of positive energy have very strong Aura which is diffused  much more around the natural color. The composition of Aura is different  to every  human , the color and  size it reveals a deeper internal world. Aura is in human in animal and in plant kingdom ,in every  source of life Each organism emits this great "light" that scientifically could be called radiation of energy nobody have  really awareness about it but sometimes we feel this phenomenon, without however see it. In 1900, the English Walter Kilner have discover that  covering a mirror with a thin layer of Dikianine it was possible somebody to see the Aura of person. In 1936,  Otto Rahn wrote a book "the invisible radiation of organisms" that the Aura is constituted by a very thin radiation, and that they become perceptible only under concrete conditions. Rahn he also discover that only our corneous is capable to conceive such radiation. The theories of Kahn found then the proof  in the eminent experiments that became with the method of photograph Kirlian.
