It may be that universal history is the history of a handful of metaphors. How often it is that the angry man rages denial of what his inner self is telling him. Some precious stones can be identified by their impurities. Experts map impurities within the stones. A secret fingerprint.
People are like that.
You often know them by their defects. The glittering surface tells you too little. Good identification requires you to look deep inside and see the impurities. There is the gem quality of total being. A good warrior is not bellicose, A good fighter does not anger, A good conqueror does not contest his enemy, One who is good at using others puts himself below them.
