In the various countries the fuel may be used for different purposes. The inhabitants of these imaginary countries may change the appearance of the fuel, but the fuel is all derived from the same source and supplies each various country, while the train itself travels deeply within each country and finds no barriers to keep it out.

Using air again as a simple analogy to our fuel for the inner senses, which is converted by the various countries or planes for their own purposes and therefore camouflaged, air in its pure state is not observed easily. And permeating everything, it could almost pass unnoticed itself since it takes on the form of that which it composes.

The brain is of your plane. You may say that the brain is the mind in camouflage. Imagination belongs to the mind. It can be used by and is used by the brain for purposes of survival, and can sometimes be probed by physical instruments. That is physical instruments can be made to make the imagination move on occasion. But imagination is a property of mind, not brain, and no physical tool can force the imagination to conceive of an original conception or idea.
