楞伽阿跋多羅寶經註解 2.53

2.53

佛告大慧：「頭、胸、喉、鼻、脣、舌、齗、齒和合出音聲。」大慧白佛言：「世尊！言說、妄想為異為不異？」佛告大慧：「言說、妄想非異非不異。所以者何？謂彼因生相故。大慧！若言說妄想異者，妄想不應是因；若不異者，語不顯義而有顯示。是故非異非不異。」

The Buddha told Mahāmati: "The head, chest, throat, nose, lips, tongue, gums, and teeth come together in combination to produce sound." Mahāmati addressed the Buddha, saying: "World-Honoured One! Are speech and discrimination different or not different?" The Buddha told Mahāmati: "Speech and discrimination are neither different nor not different. Why is this? Because that [speech] is the mark produced by its cause. Mahāmati! If speech and discrimination were different, discrimination could not be the cause; if they were not different, words could not reveal meaning, yet there is revelation. Therefore they are neither different nor not different."
