Why do we need to see Auras ?
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.
