四明十義書 2.84

2.84

上人又解豈唯真心句意，云，不獨約真心說唯心，亦不須約妄心論唯心，蓋約真妄合論說唯心義。欲救《珠指》獨約真心說唯心義也。須知《示珠指》是必死之病，縱扁鵲亦不能救，況盲醫者乎。

You also interpret the meaning of the phrase "how could it mean only the true mind," saying that it does not merely explain mind-only in terms of the true mind, nor is it necessary to discuss mind-only in terms of the deluded mind, but rather explains the meaning of mind-only in terms of discussing the true and deluded together. This is an attempt to rescue the Zhuzhi's explaining the meaning of mind-only exclusively in terms of the true mind. You must understand that the Shizhu zhi is a fatal illness: even Bian Que could not cure it, let alone a blind physician.
