An aura is an energy field that surrounds living beings, including humans, animals, and plants. The common belief is that the aura is composed of subtle vibrations of energy that emanate from the subject and can be seen as a coloured halo or field around it.
In 1939, Russian inventor Semyon Davidovich Kirlian, invented a method of taking portraits using a metal plate and an electric current that he claimed could reveal the “life force” of his subjects. Kirlian photography became the common method to record an aura at that given moment.
From the image produced, an experienced reader could suggest various aspects that might be creating those colours and even some illnesses could be detected using these results.
The good news is however that equipment is not required to see auras. Everyone can learn the skills required to detect and see them. Though it might take some time to perfect and a lot of patience in the process.
