There is nothing “paranormal” in the Universe, except our limited understanding of Nature. What we think we “know” on Earth now is just a tiny drop in the Ocean of Knowledge.
In the distant past, people admired things they could not explain and called them “miracles”. Long ago, people were able to see Auras. Advanced spiritual people such as Buddha, Christ and their immediate students were painted with golden haloes around their heads, because some artists could actually see Auras.
All is required is the knowledge how to use your senses together with your conscious effort. If you decide not to try, you will NEVER see the Aura. On the other hand, when you SEE something for yourself, no longer will you need to rely on believing someone. You will KNOW. And you can use your knowledge to learn more.
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 an electro-photonic vibration response of an object to some external excitation (such as an ambient light for example).
Auras are energy bodies, electro-magnetic energy that contains loads of information about what is going on with people, animals, plants, and so forth at a deeper level. It is also metamorphous space around a plant, animal or human body or a haze that surrounds the human body. It has also been described as a very subtle form of matter or a vital force that radiates and lies at the base of all manifested life.
Your aura, for instance, includes information about how you communicate, your truthfulness, your emotions, the use of your mind, your sexiness, and how you deal with power.
