Because this is a transportation hub, people pass through, it facilitates, but is itself not a destination. The hub is how you get someplace---besides the hub.
That's what you have been told. Because those places in big letters on the front of the bus, those street corners in tiny print in the schedule, stops the loud speaker yells out---- the point of the busy activity, the reasons you are passing through the hub---- are just a fib---those are not the places you are going. The destinations, are all, a myth.
The destinations just exist so you will keep cycling through the hub, and not noticing -- the hub. The hub only works when you do not notice it.
Do you see?
The hub is in your head.
