Subtle Glows is a term used to describe the phenomenon of Auras and Aurae. Auras are an energy field that surrounds living things, while Aurae are the energy fields that surround non-living objects. These energy fields can be seen by some people as a colored light or a halo around the object or person. Subtle Glows are often associated with spiritual or supernatural powers, and can be used to detect the presence of certain energies.
