Human aura is an electromagnetic field that emits from any living thing. It is comprised of many layers, with each aura layer having its own function or role. An aura is not separate from the physical body but is an extension of it in different composition.
To compare, the characteristics of planet Earth include physical and atmospheric layers. The attributes of each layer are different in likeness, appearance and function; each is an interconnected part incorporating the entity as entirely complete.
Human auras are similar – the aura layers relay specific feedback between our physical body and its functioning systems, our mental and emotional states of being, and they exchange information with other auras that we interact with.
