四明十義書 1.37

1.37

且上人自云：十法純明理觀，不須附事而觀。既云純明理觀，則知專是止觀約行觀心。儻稍兼事相法相，何名純談理觀？若少帶佛法生法，何名直顯心性？詰難書本徵直顯心性純明理觀，何得將事法之觀答之？

Yet the Venerable himself said: 'The ten dharmas purely clarify principle contemplation, without needing to contemplate by appending to phenomena.' Since he said it purely clarifies principle contemplation, we know it is exclusively the contemplation of the mind in terms of practice in Zhiguan. If it slightly partakes of phenomenal marks and doctrinal marks, how could it be called a pure discussion of principle contemplation? If it carries even a little of the Buddha-dharmas and sentient-being dharmas, how could it be called directly revealing the mind-nature? The *Letter of Refutations* originally interrogated [his claims of] directly revealing the mind-nature and purely clarifying principle contemplation; how can he answer it with the contemplation of phenomena and teachings?
