I see the Peach Blossoms of Spring,
   And think of old Li Bai’s answer.
 
In wordless replies, the world sings;
   In unpeopled worlds, there’s a dancer.

The referenced poem by Li Bai [李白] is entitled Question and Answer in the Mountains [山中问答] and is crudely translated as:

I'm asked why I live in mountains.
   I laugh while giving no reply.

Peach Blossoms flow from sight & mind;
   Beyond men, another Earth & Sky. 

Or, in Chinese:

问余何意栖碧山，
笑而不答心自闲。

桃花流水窅然去，
别有天地非人间。
