[Zope] Help me to be zennish

Hi, I'm reading through the documents, but I've some problems getting the Zen : In the document 'Zen of HTML methods' you tell : Folders provide a rendering context for Documents. When you view a document, you are viewing it within the context of its folder. (Rendering Context) --> This means, in my opinion, Documents, inherite the layout (or the variables) of the folder they are in. But then : A Document is a lens through which the Zope object system can be viewed. (Documents are Templates) --> But as a document inherites from a folder... then isn't the folder the lens through .... (hack, probably my bad english which is giving me problems) Tom.
