老氏讀易得間 Help me understand this, not homework My question is about the phrase 老氏讀易得間 which I have seen translated as "Laozi's school read between the lines of the I Jing."  I am having trouble getting my reading of it to the point where that makes sense.  Can anyone guide me?  I'm open to that translation being wrong, no investment on my part, just trying to get it right and understand it.  Thanks!
