You cannot see the forest for the trees.  But is it not at times a good idea to focus on the trees?  Where you place your focus is what you create.  It becomes your reality.  However limited you wish your field of vision to make, so it becomes.  However expansive your beliefs, so it is.  Are you fenced in by the trees?  Enjoy this reality.  Do you wish for greater experiences?  Wander through the entire forest, taking it all in, reveling in the variety of trees and the forest in its wholeness.
 
You are only limited by the limits of your focus.  We speak not of vision with the physical eyes.  Go within, where all at first appears dark, but is in fact the source of all light.  It is that light you focus on all that you see and all that you wish to see.  Thus your world expands.
 
Are you getting an idea of the playfulness of creation?  Expand your focus or contract it, but have a ball while you’re at it.
