It's a little crude but that's what myth does. Myth is sort of a cloud chamber in which spirit is imaged on its course. When you look at the mythological structure of an organization it's not one story or the other story, it's the dynamic interrelationship between all the stories creating that resonance. You can think of the organization as a drum head, and each one of the stories is sort of a tuning knob on that drum head. What you end up with is the sound of the organization.
Myth appears through certain very concrete things.
When you hear the mythology of any organization there are no trumpets sounding. It's just tales of everyday things. It appears in color, form, sound, vocabulary of that organization. When it comes to understanding or changing, or assisting an organization, it may well be that the color on the wall is the critical piece of the story that needs to be changed. They don't need any memos.
