Hexagram 36, Brightness Hiding or Brightness Injured, can certainly be a danger-signal in a reading: hide your light, risk of injury ahead. But it is also a postive strategy, as this Deng Ming-Dao quotation from Donna Woodka’s Changing Places blog shows. (One to subscribe to, I think.)
It also shows very naturally how Release, hexagram 40, can be the hidden core of Brightness Hidden: it frees you from being defined by your knowledge or your job description. And that can also mean greater personal autonomy.
