仁王護國般若經疏 3.20

3.20

「善男子」下，第二約無聽說以明空相也。文中法喻合，可見。聽說如虛空者，《大品》云「聽如幻人聽，說如幻人說，故無聽說。」《淨名》云「夫法說者無說無示，其聽法者無聞無得。」「法同法性」者，《淨名》云「法同法性，入諸法故。」以此例諸，故皆如也。

From "Good sons" onwards is the second, clarifying the characteristics of emptiness in terms of the absence of hearing and preaching. In the text, the Dharma, the analogy, and their combination can be seen. Hearing and preaching being like space: the Pañcaviṃśatisāhasrikā says, "Hearing is like an illusory person hearing; preaching is like an illusory person preaching; therefore there is no hearing or preaching." Vimalakīrti says, "In preaching the Dharma, there is no preaching and no demonstration; those who hear the Dharma have no hearing and no attainment." "Dharmas are identical with the dharmatā": Vimalakīrti says, "Dharmas are identical with the dharmatā, because they enter all dharmas." Taking this as a parallel for all, they are therefore all thus.
