There is much mystery surrounding the Illuminati and this is for purpose. This is their method of operation for all devious acts, criminal or otherwise, which they desire to keep concealed from the public.
I would describe it briefly this way.
The Illuminati are comprised of the Bankers. All others within government, military serve the Illuminati. If the Illuminati want war, the government and military serve them. If the Illuminati want the stock market to crash, those who are paid zillions within this industry, will crash it.
Freemasonry is the father of all secret societies. I refer to it as the OCTOPUS. The tentacles of the OCTOPUS comprise all other secret societies that infect all aspects of our lives from education to banking, etc.
Mind control plays a prominent role in this regard.
There are masters and there are servants.
