四明十義書 1.88

1.88

故《扶宗》云：以一念識心為境，用三觀觀之，使性德開發。既是圓教三觀，自合約於三千論其空中也。復明開發性德金光明，豈不含三千妙理耶？何得以未詳之文破已解之語。

Therefore the Fuzong says: 'taking a single thought-moment of the consciousness-mind as the object, one contemplates it using the threefold contemplation, causing the inherent virtue of the nature to unfold.' Since this is the threefold contemplation of the Perfect Teaching, it naturally ought to discuss emptiness and the middle in terms of the three thousand. Moreover, in explaining the unfolding of the inherent virtue of the Golden Radiance, how could it not contain the wondrous principle of the three thousand? How can you use an unexamined passage to refute words that have already been explained?
