Some people can see past the 3D color/aura spectrum and see the frequencies of light that are streaming through now. These colors may appear as a rainbow or twin rainbows.
An aura is the electro magnetic field surrounding an object. Some people refer to this field as a bio-energy field. Auras vibrate to different color, sound and light frequencies. The color spectrum varies with one's physical, emotional, mental, and spiritual states. Your aura usually consist of more than one color at a time.
In truth this energy field not only goes around you, but moves within your body as well. It is not just the outside of your body that is made of electro magnetic energies, every part of you and everything you experience in third dimension. It can extend out very far or remain close to the body, which occurs when the person is protecting themselves from someone or something.
Auras are in a constant state of flux. If an aura sways back and forth, the person has a chemical imbalance, due to drugs, medication, drinking, a chemical imbalance in the body. If a person has no aura or the aura appears black, then the person has crossed over (in part/totally) as their physical body no longer has an electro magnetic energy field.
Some people can psychicly look at the subject and see images within a person's aura. These images may include symbols/archetypes, people, digits, or even another aspect of the person's soul that is coming through in their third dimensional aura from another realm.
When two people have just been lovers, they will show up in each other auras, the color of their auras depending on the nature of their relationship.
When people have done healing work together or shared any physical contact, they will share a common auric field for a period of time as they have just merged their electro magnetic energies.
Auras can be seen physically, or sensed psychicly, or both. To practice seeing auras, have the subject stand in front of a white background and look to the side of their body, either side is fine (daylight is often the best light as the sun's rays are full spectrum). If you watch the person for a minute, you will see their electro magnetic energies as sort of wavy lines of energies. This looks a lot like the energy you see when you are watching an airplane taking off in a movie.
Do not strain you eyes, relax. You might want to let your eyes go a little out of focus while you are looking for an aura. You may only see the aura for a few seconds, then it will disappear. After you see that energy, you may also see or sense a color frequency, maybe two or three colors, in the aura. After several minutes you should be able to see some sort of energy field around the person, even if you cannot determine the color. Remember, that auras change all the time according to the person's mood and environment.
As with all psychic tools, learning to read auras seems easy for some people while others need lost of practice. The color of your aura is determined by your emotions, physical surroundings, spiritual work you are doing, items in the room, such as crystals which can magnify or change the colors of any aura. Anything that can affect an electro magnetic field can affect a change in one's aura. As everything that is in our reality is created from electro magnetic energy, everything has an aura (e.g. plants, animals, etc.).
When you are working as a healer, you are bringing balance to the person's electro magnetic field. You should observe the person slowly then determine if they have holes in their aura. It would look as if the Electro-Magnetic energies had suddenly stopped. This will tell you where there is a problem or imbalance in their physical body. I always suggest you discuss the problem with the person first. All physical illness comes from the emotional body which created the problem in the first place. You must find the psychological cause of the problem first, to determine if the person actually wants to be healed on an emotional and soul level. If they are they are not ready, the healing and balancing can only last for a sort time and will revert back, or manifest in another area of the body. All healing must be done on the soul level first. You can use your hands in a slow sweeping motion over the part of the aura where the energy (chi) does not appear to flow properly. As you move your hands across the person's aura - you should both experience some sort of change in the energy flow. You do not touch the person, just the auric field of that person. This healing technique is know as Therapeutic Touch.
If you would like to see your own aura, find a mirror that is in a well lit room, relax. Look at your head or head and shoulder area. Focus on one side of your head. Soon you should be able to see the electro magnetic energies as a field of light around your head.
Do you want to feel the electro magnetic energies coming from your body? Try holding the palms of your hand facing each other, about two inches apart. Wait a few seconds. You will feel something. If your hands are nervous and cold, that will hamper the energies. Once you begin to feel the sensation of electro magnetic energies between your palms, move them slowly to and fro. You will feel the movement of your aura. Look between your hands to see the electro magnetic energies, your aura. Try moving your palms further and further apart, slowly. See how far you can go before you no longer feel the 'pull'. Remember to check periodically by moving your hands slightly and slowly. Now try pointing your fingers towards each other and feel those energies. Again move your finger tips to and fro. You can repeat this with another person.
Aura energies are linked to colors, the chakra system, musical tones/notes, as they all resonate to the same frequency. Sound, light and color are all interconnected at source.
You can have fun changing your aura while taking an Aura/Kirlian Photo. Meditation or working with anything that can enhance your electro magnetic energy fields will raise your frequency and move you to a higher frequency color of light. In other words, hold a few clear quartz crystals and meditate, take your picture, it will have a clear white tone unless you have a serious medical problem.
As you can see all things are connected by the flow of the electro magnetic energy fields that create our reality.
