《淮南子·精神训》
所以，知晓宇宙之广大的人，是不能用生死来胁迫他的；知道以中和之气来养生的人，是不能拿天下权势利禄来引诱他的；懂得未降生时的快乐的人，是不能以死亡来吓唬他的；明白许由比虞舜高贵的人，是不会贪图物质享受的。
故知宇宙之大，则不可劫以死生；知养生之和，则不可县以天下；知未生之乐，则不可畏以死；知许由之贵于舜，则不贪物。
Therefore, for those who know the vastness of the universe, it is impossible to intimidate them with life or death. For those who know the principle of maintaining life with harmony, it is impossible to tempt them with power or profit. For those who understand the happiness of being unborn, it is impossible to scare them with death. For those who understand that Xu You is more noble than Yu Shun, it is impossible for them to pursue material enjoyment.
