撫州曹山元證禪師語錄 1.57

1.57

僧問：「雪覆千山，為甚麼孤峯不白？」師曰：「須知有異中異。」僧云：「如何是異中異？」師曰：「不墮諸山色。」

A monk asked, "When snow covers a thousand mountains, why is the solitary peak not white?"
The Master said, "You must know that there is the difference within difference."
The monk said, "What is the difference within difference?"
The Master said, "Not falling into the colors of the various mountains."
