Do Spirit-beings have auras, or are these restricted to living physical forms?

As we have said every living thing has an aura and so these are not unique to existence in the physical dimension. The aura seen around a person while he or she is on the physical plane, consists of both a physical and an etheric or metaphysical aura. Some people who see auras see only the aura relating to the physical body, while others can see both of them. On the astral spheres the auras are much brighter, or perhaps it would be more correct to say they are seen with greater clarity.
