Psychogeometry is the idea of an energy source, or extremely low level framework, based around a physical location. 

Some people see it as a real force behind cities/tows/forests/countries/anything locational, or as a way to combine all the elements within those systems into a massive "idea." 

To put it simply, it treats places as entities. Towns and cities have a feeling; from the way the streets are planned out, to the types of buildings or structures, to the types and volumes of people, to the vehicles that move through streets and underground subway systems. 

It's a way to create a body map of a place, and then use the "organs" and "blood vessels" of the location to explore a place or idea internally.
