I think:
  This relates to understanding the mental model?

My view:
  'here' (.) is the current node / position in the input document tree
that is being processed.

View the 'tree' in your head, and you may see the parents, siblings,
children of this node (point in the document tree).
Ken Holman has (had?) a good picture of this which may help.
  Then decide what you want to do next?
  When you have this model in your head comfortably, you may be happy using
xsl:apply-templates to process the children of the current-node, using
the xsl 'model'.
