大乘百法明門論開宗義決 1.38

1.38

般若經等為非了義就偏說故等者。偏就空門遣一切相。以無自性即名勝義。由勝義故世俗成空。不由世俗勝義成有。故說皆空就偏說也。

Regarding "the Prajñāpāramitā Sūtras and others are of non-definitive meaning because they are spoken from a one-sided perspective," etc.: They eliminate all marks solely from the approach of emptiness, taking the absence of intrinsic nature as the ultimate truth. By virtue of the ultimate truth, the conventional becomes empty; it is not that by virtue of the conventional, the ultimate truth becomes existent. Therefore, saying that all are empty is spoken from a one-sided perspective.
