People create on a planet-wide basis what they imagine or feel.
Subtle Fires
The planet has various planes, with strong correspondence both with and within the [Human Etheric]? and [Human Aura]?. In much the same way as earth, water and air, these planes support and maintain lodgements necessary for planetary state, and also lodge newly invented or discovered concepts. They probably relate to what are commonly accepted as the Atmosphere?, Ionosphere and Magnetosphere. Human knowledge of these planes is very sketchy but also subtly and powerfully influential on every being on the planet.
It is fairly apparent that humans both transmit and receive within these planes. This may be done via the finer systems in the human complex during experiences such as communion, telepathy, knowings, and suchlike. In less happy and more exploitative circumstances, transmission (and subsequent re-transmission) is via very much coarser means such as the impositions of memes that are often seen in present TV programming and many other outlets.
