Thirty years ago ( 1980s) saw a film using kirlian cameras showing pictures/videos of the interchange of energies between two people when they feel love or hate, the halo/aura around plants and people. The cameras were invented by the Russian scientists Kirlian, husband and wife in 1939.
In another film, there was a study done by a mayor USA university, I believe Stanford, where the department of Psychology/Parapsychology, weighted the bodies of people closer to time of death. There was a loss of 3.3 grams of sudden weight loss that could't be explained even counting the air in the lungs or the evaporation of liquids in the human body. There was also pictures of the energy that shows leaving the body at the time of death using Kirlian cameras.
Nowdays, there is a new camera called GDV cameras that take much better pictures and film of energies and it's been used in different areas of health and physical research. We can clearly see images of what has been called "ghost" or "soul" once a person dies.
We have 7 chackras and 7 bodies, the picture of the energy leaving the body is the astral body, which is less dense than our known physical body but still physical which can be weighted. The soul, spirit, mental, or other bodies are of much higher frecuencies.
There are places on the world where Doctors look at these aura pictures to determine future sicknesses based on the shape of the aura.
