to me it is just being simple (not an easy word to explain using the throttling control of words)
you will notice that some can handle much flow and some need very little to sustain their existence in this reality. eg some can handle many inputs whilst others need a few inputs (otherwise it is not easy to cope)
this may be conditioning or it may be an self protection mechanism
This is very similar to the number of faces humans can apply to the world.
Throttling is to me a protection mechanism, when the flow is too strong and from many directions humans sink into a turtle shell.
Flow can be the sense from the outside world or internal, it just depends on the ability/makeup and experience one has in this life cycle.
perception and experience and bias are powerful corridors in humans
