金剛三昧經論 3.16

3.16

經曰　舍利弗言：「一切萬法皆悉文言，文言之相即非為義，如實之義不可言說，今者如來云何說法？」

The sūtra states: Śāriputra said, "All the myriad dharmas are entirely letters and words, but the character of letters and words is not the referent, while the real referent as it is cannot be spoken. How then does the Tathāgata now teach the Dharma?"
