四明十義書 2.215

2.215

然又詰難書自問純談理觀不依陰心，乃是正詰常坐等約行觀法，何不揀示識心為境？何不明十乘三觀？上人却用事法不待陰境答之，有何干涉？縱令上人此義十分全成，何能救於約行無境？況十分全壞耶？

Furthermore, the Letter of Interrogation itself asked: 'Purely discussing principle contemplation without relying on the deluded mind of the aggregates is precisely the interrogation of the contemplation methods based on practice, such as the constantly sitting [samādhi]—why does it not select and indicate the cognitive mind as the object? Why does it not clarify the ten vehicles and threefold contemplation?' You, however, answered by using the phenomenal method not awaiting the object of the aggregates—what relevance does that have? Even if this doctrine of your reverence were fully ten-tenths accomplished, how could it rescue the lack of an object in [a contemplation] based on practice? How much less so when it is ten-tenths completely destroyed!
