Our True Great Teacher-Zen Master Seung Sahn Haeng Won

  

So you must keep very strongly a closed mouth and you must learn from the blue sky, the white clouds, deep quiet mountains and the very noisy cities. They are like this, that is your true great teacher.

-Zen Master Seung Sahn Haeng Won 
所以你必须尽你所能地闭上你的嘴巴,然后向蓝天、白云，幽静的山和喧闹的城市学习。它们只是如此。这便是你真正伟大的老师。

-崇山行愿禅师
