The quality and density of your aura.
The aura is an invisible field of subtle energy that envelops and protects your body. It is a cocoon of personal and cosmic energy that protects you from the outside world like a cloak or shield, and gives you charisma, radiance and power.
In some people the aura is solid and closed. These people are "on their own" and not easily influenced. Other people have a thinner, smaller aura, sometimes with holes through which personal energy leaks and other people's energy can enter. These people experience their own power and center less strongly, and can have to deal with a fleeting consciousness and rapid overstimulation by impressions from outside.
The quality and density of your aura is determined by the functioning of the chakras and by how emotionally and mentally balanced you are. But energy from outside can also balance and strengthen your aura. Fluorite is a natural aura booster and cleanser that provides the subtle energy field around you with new strength and strength.
