首楞嚴義疏注經 10.91

10.91

「二者、是人諦觀其心互互無處，因無得證。有人來問，唯答一字，但言其無，除無之餘無所言說。」

"Second, this person closely contemplates his mind where each mutually ceases, and through nonexistence attains realization. When someone comes to ask, he answers with only a single word, merely saying 'no', and aside from 'no' has nothing to say."
