金剛三昧經論 3.18

3.18

經曰　佛言：「我說法者，以汝眾生在生說故。說不可說，是故說之。我所說者，義語非文；眾生說者，文語非義。非義語者皆悉空無，空無之言無言於義，不言義者皆是妄語。如義語者，實空不空、空實不實，離於二相中間不中，不中之法離於三相，不見處所，如如如說。如無無有，無有於無；如無有無，有無於有。有無不在，說不在故，不在於如；如不有如，不無如說。」

The sūtra states: The Buddha said, "When I teach the Dharma, it is because you sentient beings are within birth-and-death that I speak. I speak the ineffable; therefore I speak it. What I speak is speech of the referent, not letters; what sentient beings speak is speech of letters, not the referent. Speech that is not of the referent is entirely empty and non-existent; words that are empty and non-existent say nothing of the referent; those that do not speak of the referent are all false speech. What accords with speech of the referent is that the real is empty yet not empty, and the empty is real yet not real; it is free from the two characteristics, and within the middle it is not middle; a dharma that is not middle is free from the three characteristics, with no place seen, spoken in accordance with thusness just as it is. As there is no non-existence, there is no existence in non-existence; as there is no existence, there is no non-existence in existence. Existence and non-existence are not present, and because speech is not present, it is not present in thusness; thusness does not possess thusness, yet it is not without being spoken in accordance with thusness."
