Verse 47 tell us that it is good to keep a beginner’s mind for a beginner’s mind has many possibilities whereas an expert’s mind has few. A beginner sees thing that the expert dismisses. It’s always good to keep all options open; don’t close that door, don’t burn that bridge for you never know when you might have to travel that path again. Fate has its funny and ironic ways. The seemingly impossible happens. That key you throw away today may unlock the locks of tomorrow.
