Dicyanin Screen
This device is described in the Dreams & Dreaming course. It is a way for the naked eye to see the first three layers of the human aura. The device consists of two plates of glass with a dycanin dyed liquid between them. Dicyanin is a coal tar dye. Some say that a subject’s aura can be seen through the screen, while others say that one must look at a bright light first, and then look at the subject through the screen.
There have been several doctors in the past years who have used this technology for discerning illnesses in their patients and diagnosing their condition. This could be another advance in medical practices that would meet with a terrible end with the AMA if it was as precise as the Rife Machine, but up to this point, there is still much mapping of the human aura that needs to be done. Humans have only touched the tip of the iceberg on this huge and limitless subject!
