1.562

微妙是菩提諸法難知故　肇曰。諸幽遠難測。非有知之所知。以菩提無知故無所不知。無知而無不知者妙微之極也。

"Subtle and wondrous is bodhi, because all dharmas are difficult to know." Sengzhao says: The profound and distant is difficult to fathom; it is not what can be known by having knowledge. Because bodhi has no knowledge, there is nothing it does not know. To have no knowledge and yet have nothing one does not know is the culmination of the subtle and wondrous.
