Mystical Energy Field is a term used to describe an AURA, which is a luminous radiation or energy field that surrounds a person or object. It is believed to be an emanation of the spiritual and emotional state of the individual, and is often associated with healing and spiritual growth. The AURA is said to be visible to some people with special abilities, such as clairvoyance. It is also believed to be connected to the chakras, which are energy centers in the body.
