What is the Aura?

Everything in the Universe seems to be just a vibration. Every atom, every part of an atom, every electron, every elementary “particle”, even our thoughts and consciousness are just vibrations. Hence, we may define the Aura as a electro-photonic vibration response of an object to some external excitation (such as an ambient light for example). This definition is sufficient for the purpose of reading Auras, providing that we can train ourselves to see the Aura vibration.
Aura around living (conscious) objects (people, plants ...) changes with time, sometimes very quickly. Aura around non-living object (stones, crystals, water...) is essentially fixed, but can be changed by our conscious intent. Above facts have been observed by scientists in Russia, who have been using Kirlian effect to study Auras for the last 50 years.
The Aura around humans is partly composed from EM (electromagnetic) radiation, spanning from microwave, infrared (IR) to UV light. The low frequency microwave and infrared part of the spectrum (body heat) seems to be related to the low levels of the functioning of our body (DNA structure, metabolism, circulation etc.) whereas high frequency (UV part) is more related to our conscious activity such as thinking, creativity, intentions, sense of humor and emotions. Russian scientists, who seem to be about 3 decades ahead of everyone else in Aura research, make experiments suggesting that our DNA can be altered, by influencing its microwave Aura. The high frequency UV part is very important and most interesting but largely unexplored. And this part can be seen with naked eyes.

Colors and intensity of the aura, especially around and above the head have VERY special meanings. Watching someone's aura you can actually see the other person's thoughts before you hear them expressed verbally. If they do not agree with what this person is saying, you effectively see a lie every time. No one can lie in front of you undetected. We cannot fake the Aura. It shows our True Nature and intentions for everyone to see.
Also, aura is our spiritual signature. When you see a person with a bright, clean aura, you can be SURE that such person is good and spiritually advanced, even if he/she is modest and not aware of it. When you see a person with a gray or dark aura, you may be almost SURE, that such person has unclear intentions, regardless how impressive, eloquent, educated, "good looking" or "well dressed" he/she seems to appear.
It is ESPECIALLY important to check the aura of any religious leader, "spiritual teacher", "master" or a "guru". Such a person should have a clearly defined yellow-golden halo around the head. If he/she does not have it, you are MUCH better on your own.

Everyone has an Aura. But most people on Earth have VERY WEAK and dull Auras. This seems to be a direct consequence of their life long materialistic attitude negating and suppressing the development of consciousness, cultivating fear, envy, jealousy and other similar emotions. Such attitude suppresses their True Nature, and their Auras seem to become suppressed too.
When you learn to see Auras, be prepared for a REALLY HARD question: “Can you tell me what my Aura is ?” and the situation when you don't see any Aura or you see something you don't want to talk about. One of the best answers I found is “why don't you learn to see it for yourself ? “. And this is one of the main reasons why I teach people to see auras.
When people realize that their Aura is on display and many people are able to see it, they will watch what they think. And they will try to see and improve their own Aura. In the process they will become better and wiser, being able to recognize intentions of other people. Surely, the entire world will become much better if all people can see and read Auras.
