肇論新疏 2.107

2.107

亦義引《放光》等經。由難者依名求實，二名既違，謂聖心亦異。不知般若非名非相，故引經以遮，令忘名會旨。經約遮詮可知。斯則下，論辭略釋無名無說，以起下文。

This also quotes the meaning of the Fangguang [bore jing] and other sūtras. Because the objector seeks reality based on names, and since the two names contradict each other, he claims that the sage mind is also divergent. Not knowing that prajñā is neither name nor mark, he cites the sūtra to refute him, causing him to forget names and meet the purport. The sūtra can be understood as apophatic discourse.
