6.72

周之問曰。盡有盡無非極莫備。知無知有吾許其道家。惟非有非無之一地。道言不及耳。非有非無三宗所蘊。儻餘瞻慮唯足下其眄之。念不使得意之相爽。移失於。有歸耳。

Zhouzhi asked, saying: "Exhausting existence and exhausting non-existence—unless one has reached the utmost, one cannot be completely furnished with both. As for knowing non-existence and knowing existence, I grant that to the Daoists. It is only the single ground of neither existence nor non-existence that the words of the Dao cannot reach. 'Neither existence nor non-existence' is that which the three schools contain. If you perchance consider this, you need only glance upon it, sir. Reflect on this so as not to allow the mutual divergence of 'grasping the meaning', shifting into a loss of where to return."
