Stone Proverbs No.7 : Other People’s Mountain Stones
Share
Tazan no Ishi
Even trivial behavior, mistakes, or criticism from other people can become a practical lesson that sharpens your character and improves your actions. This is the core message of a classic proverb often explained through a simple image: a rough stone from someone else’s mountain can still work as a whetstone to polish a gem.
Meaning
The proverb teaches a disciplined way to learn: do not waste outside signals. Instead, convert them into self-improvement. It is not about mocking others. It is about extracting a usable lesson and refining your own standards.
Roots and origin
The idea is commonly traced to imagery associated with the Book of Songs (Shijing): even a plain stone from another mountain can be used as a whetstone to polish a precious gem. In other words, you do not need perfect tools to improve. You need the skill to use what is available.
When to use it
Use this proverb when you want to treat someone else’s failure as a mirror, or when you want to remind yourself to stay humble and disciplined. It is especially useful when you receive uncomfortable feedback: the sharper the friction, the stronger the polish.
