四明十義書 1.196

1.196

既云但觀理具，俱破俱立，俱是法界。豈非令行人於能造心，唯觀理具三千俱空假中耶？若便以所造外事為境，何名但觀理具俱破等耶？

Since it says: 'one only contemplates inherent possession in principle; both refuting and establishing together, all are the dharmadhātu,' does this not instruct the practitioner, with regard to the producing mind, to contemplate solely the three thousand inherently possessed in principle as all being empty, conventional, and the Middle? If one immediately takes the produced external phenomena as the object, how could it be called 'only contemplating inherent possession in principle; both refuting [and establishing together]'?
