楞伽阿跋多羅寶經註解 2.54

2.54

The seven places such as the head are what the breath-wind relies upon, combining to produce sound and form speech. Since it arises in reliance upon multiple conditions, sound is false; hence there is the second question of difference and non-difference. The Buddha's answer that they are neither different nor not different is because speech merely arises taking discrimination as its cause. He also said that if they were different, discrimination could not be the cause; if they were not different, speech could not reveal meaning—how then could there be the revelation of speech? Therefore he says they are neither different nor not different.
