From a website on aura and chakra:

From a website on aura and chakra:
"The aura is the electromagnetic field that surrounds the human body [Human Energy Field-HEF] and every organism and object in the Universe.
The Human Energy Field as a collection of electro - magnetic energies of varying densities that permeate through and emit or exit from the physical body of a living person. These particles of energy are suspended around the healthy human body in an oval shaped field. This "auric egg" emits out from the body approximately 2-3 feet (1 metre on average) on all sides. It extends above the head and below the feet into the ground. 
The aura consist of seven levels/layers/auric bodies . Each one of the subtle bodies that exist around the physical body, has its own unique frequency. They are interrelated, and affect one another and the person's feelings, emotions, thinking, behaviour, and health as well. Therefore a state of imbalance in one of the bodies leads to a state of imbalance in the others."

Does this not sound like XM to you? Could it be that we emit XM? Or does it simply cling to us?

Also see chakras: Blue (throat) and Green (heart) as part of many on the body that work together for spiritual awareness. Also purple, spiritual thought and flashes of inspiration.
