what is the best way to visualize an aura?

First of all, you have to be ready, and to have the gift. Then you can actually see it even with your eyes closed. I see them best with my eyes closed. The aura is a subtle energy that you perceive in your Soul more so than with your eyes. You can not train in this, you can only develop the ability by following a subtle path and by working on your own sensitivity.

Unless you are already doing so, start with meditation, yoga, or something like that.

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.

Joining a sect or a religion that is led by incompetent people without good Auras is very dangerous for your consciousness. Where is the danger ? When the time comes to really use the information stored in your consciousness from this lifetime, there may be almost nothing useful there, if you focus your life on following rituals and the flock of other people. In such case it is necessary to re-learn everything from the beginning. Most sect, religion and political leaders have only two things in mind: money and power to control people. And you can SEE it in their Aura for yourself. Imagine changes on Earth if many people can see Auras of their leaders and start choosing them on the basis of their Auras.

By reading Aura it seems possible to diagnose malfunctions in the body (diseases) long before physical symptoms become evident. By consciously controlling your Aura you can actually heal yourself.

However, healing of the physical body is nothing in comparison to what seeing and reading auras can do for our consciousness, spiritual development and our awareness of Nature.

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.

I've never visualized an aura, only seen them. I don't know how to explain it, it just happens or it doesn't.

Fasting prayer and praise! These will help you . Fasting can be difficult. Try a five day fast, or maybe days on end with only small amounts of food. Get close to God he will open your eyes in special ways. Don't seek anything threw divination or unholy practices.

yoga and meditation certainly help develop the power to see auras

Vipasana (buddhist meditation) and Trataka(hindus tantrik meditation) can help a lot

Maybe this is because they are not real. :-)
