Thanks to this discovery about the aura, its composition could know each time with greater accuracy. Thus, we would have that aura is composed of several layers, each one superimposed on the earlier, and that on the basis of the outline of the physical body, is spreading outwards from the same, arriving to be seen with total clarity up to three of these layers, and was called which according to the following description: first layer or double Ethereal : In this layer you can see a small dark strip of pale grey, extended throughout the body, adjusting to body shape with total accuracy. The second or Aura Interior: In this second layer is observed that its width is about six inches, and just like the first also conforms to the contours of the body, presenting a greater colour or not, depending on the State of health of the person, both physical as psychological or emotional level. The third or outer Aura: this layer begins where ends the second layer or internal Aura, and its width comprises eight to fifteen centimeters. A curious fact was that in women, this third layer, was much greater than in the men, without knowing the reason for such a phenomenon. Thus, while the same auricas features in which the study was based appeared in all men, in women these were different, varying their auras as they had more age and acquiring a more soft and subtle tone. Another phenomenon of great importance that Dr. Kilner paid attention, was to prove, as when coincided two types of auras, a strong and healthy and other auras, weak without just energy, these latest auras weak, they absorbed the force of other auras strong and healthy. That is why many clairvoyants and psychics when they detect that kind of weak auras, avoid contact with them at all costs, since in case if not, not only lose part of your positive energy, but they may take long time to regain their powers.
