問：且如大乘一切色上有質礙性，此名有性。色法即有，非色法無，名同異性。此之二性與色等法，亦得名為亦一亦異、非一非異，還同外道，如何破他？

Question: In the Mahāyāna, on all matter there is the nature of spatial obstruction; this is called the existence-nature. Material phenomena possess it, whereas non-material phenomena lack it; this is called the identity-difference-nature. These two natures and material phenomena can also be designated as both identical and different, and neither identical nor different, which is still the same as the non-Buddhists. How, then, can one refute them?
