《菜根谭》英译（磨练福久、参勘知真）

一苦一乐相磨练，练极而成福者，其福始久；一疑一信相参勘，勘极而成知者，其知始真。

Repeatedly tempering oneself through the interchange of weal and woe enables one to attain long-term happiness. Repeatedly testing and checking in a process of doubt to belief and from belief to doubt enables one to attain true knowledge.

（保罗·怀特 译）

A person should temper himself by repeatedly experiencing both hardship and enjoyment; only in this way and when it has been done to the utmost can the fortune he attains remain long. A person should testify his researches by being open to belief and doubt over and over again; only in this way and after every bit of effort has been made can the knowledge he acquires become true.

（周文标 译）
