維摩義記 4.20

4.20

言說既無，請酬義絕，故「離問答」。「是為」下結。前諸菩薩雖復遣相，留言對法即是其二，亡言絕對方是不二，故今結之無言說等為入不二。

Since speech is absent, the meanings of asking and responding are terminated; thus it is "free from questions and answers." Below "This is," he concludes. Although the preceding bodhisattvas eliminated characteristics, retaining words to counter dharmas is still duality; only when words are extinguished and counterparts eliminated is there non-duality. Therefore, it now concludes that having no speech and so forth is entering non-duality.
