Everything in the Universe seems to be just a vibration. Every atom, every part of an atom, every electron, every elementary “particle”, even our thoughts and consciousness are just vibrations. Hence, we may define the Aura as a electro-photonic vibration response of an object to some external excitation (such as an ambient light for example).
This definition is sufficient for the purpose of reading Auras, providing that we can train ourselves to see the Aura vibration.
Here you can find a lot of research and info regarding Aura and spirituality healing details.
