If you want a shorter version, "grug brain, monk brain" pretends to profound, like "Zen mind, beginner's mind," but it's just a lazy take. If "grug brain, monk brain" was poetry, it would say:

  We shall not cease from exploration
  And the end of all our exploring
  Will be to arrive where we started
  And it'll look exactly the same because travel is pointless.
