“Encourage and listen well to the words of your subordinates. It is well known that gold lies hidden underground.” — Nabeshima Naoshige (1538 – 1618) in Ideals of the Samurai (translated by William Scott Wilson).
This is an idea all too often forgotten or ignored. And most subordinates are very hesitant to speak their minds. But even in that something can be learned. It just takes lots of paying attention and reading the signs.
I’m always amused when I read the ancient Chinese texts and the various ministers in a kingdom begin reporting sightings of bizarre, mythical animals. That was their way of, very indirectly, saying that something was wrong with the government. Effectively, their reports of monstrosities were a safe way of declaring that Heaven and The All Under Heavan (the kingdom) were not in harmony, thus producing abominations.
