Instead of trying to see auras, it is easier to feel and control your own aura and observe its effects on yourself and other people.
We perceive the aura unconsciously in interactions with others. A simple exercise can vividly demonstrate the reality of the energetic field surrounding an individual.
The human aura or biofield spins and pulsates like a bubble. Experiments [1] [2] have detected an apparent rotating field around the body.
A simple way to control the aura is to imagine it spinning. You can enlarge it by spinning it one direction, and shrink it by spinning in the opposite direction.
It is not necessary to make a detailed or lighted mental picture of the aura in order to spin in or out. While visualization can help, ultimately the intention should be enough.
It was learned long ago that shrinking the size of the aura (spinning in) tends to withdraw a person's energy and increase separateness from others, while expanding the aura by spinning out increases emotional contact and engagement with the surroundings. Spinning in appears to generate a subtle push away from others, while spinning out issues a magnetic pull.
In the figures below, two people are at typical conversational distance. The two should relax and be calmly attentive to subtle sensations and body position.
On the left, Person A has reduced his aura by imagining and spinning in. Both A and B will typically feel a push away from each other, as indicated by the arrows.
In the right image, A has increased his aura by spinning it out and making greater contact with the aura of Person B. Both should feel a pull toward one another. An observer may notice the pushing or pulling effects.
You can experiment to establish which direction shrinks the aura, thus creating a push or separation from others; and which direction expands it and makes you and others feel closer and more present.
In other words, some spin one way, some the other way.
Person A should not try to affect Person B, but should limit his imagination only to his own aura. Person B should stand easily.
The people involved should honestly report their experiences. Person B should avoid resisting the effects or falsely report that he felt nothing. That said, in some experiments the person in B's position has had to use considerable muscular effort in order to remain upright when impacted by the auric forces.
Spinning your aura close-in can help maintain your calm in a crowd or emotionally charged situation, or when surrounded by fanatical or intoxicated persons.
On the other hand, an expanded aura will increase your sensitivity. It could alert you to others' intentions, enabling you to exit the scene before an incident occurs.
