四明十義書 1.65

1.65

且據上人心性之義，則彰其失錯解未除也。何者？詰難書引《金錍》及《大意》不變、隨緣名心，以證所觀是隨緣所成一念妄心也。上人乃輒云：緣有染淨，隨染緣作九界心，隨淨緣作佛界心。乃斥予不合將隨緣一向在染，及堅執心性名通真妄。

Furthermore, judging from your reverence's understanding of the meaning of mind-nature, your errors are made manifest and your mistaken understanding remains unpurged. How so? The Letter of Interrogation cited the Jinbi and the Dayi on "unchanging and following conditions being called mind" to prove that the object of contemplation is the single thought-moment of deluded mind produced by following conditions. Your reverence then went so far as to say: "Conditions are both defiled and pure: following defiled conditions it forms the minds of the nine realms, and following pure conditions it forms the mind of the Buddha realm." You then censured me for inappropriately restricting following conditions exclusively to the defiled, and for firmly holding that the name "mind-nature" applies to both true and deluded.
