法華玄論 1.16

1.16

答：此經云「是法不可示，言辭相寂滅。」若有法可說，乃說非法，非說法也。法不可聞，若有所聞，乃聞非法，非聞法也。

Answer: This sūtra states, “This Dharma cannot be shown; the characteristics of words are extinguished.” If there is a dharma that can be preached, that is preaching non-Dharma, not preaching the Dharma. The Dharma cannot be heard; if there is something heard, that is hearing non-Dharma, not hearing the Dharma.
