Below is a screen capture from the fourth part of Bill Moyers’ highly recommended six-part interview of Joseph Campbell “The Power of Myth”. (You don’t have to see them in the right order. I suggest starting with the second or third to test your interest. All parts can be found on Google Video as well as on public torrent trackers.)
This is a depiction of the medieval symbol “the wheel of fortune”, which Campbell uses to express what he thinks is the the central message of myths in general: The contrasting of the drama of the circumference of this wheel to the stillness of the hub is a call for us to turn inward to the hub of existence, to find a home in consciousness rather than attaching ourselves to comforts or recognition from our peers — or to suffering or death for that matter (as perhaps Christians in particular tend to attach themselves to). All of these things are secondary aspects of reality. Non-central. Not where we should place our center.
