金剛般若經旨贊 1.15

1.15

經。汝今諦聽當為汝說　贊曰。此勅聽許宣也。汝今諦聽。即是勅聽。當為汝說。即是許宣。諦謂審諦。顯離三失。謂即散亂輕慢顛倒。如次猶如覆漏穢器。而即能生三種功德。謂聞思修。勝三慧也。由此方堪聽受正法。故智度論所說偈云。聽者端示如飢渴一心。入於語義中。聞法踊躍心悲喜。如是之人可為說。故先勅聽。方復許宣。

Sūtra: “Listen now attentively, and I shall explain it for you.”
Commentary: This is commanding them to listen and promising to expound. “Listen now attentively” is commanding them to listen; “I shall explain it for you” is promising to expound. “Attentive” (dì) means careful and precise, showing freedom from the three faults: distraction, contempt, and inversion, which correspond respectively to an overturned vessel, a leaking vessel, and a defiled vessel. Thus one can produce the three kinds of virtues, namely the superior three wisdoms arisen from listening, reflection, and cultivation. Through this alone is one capable of listening to and receiving the true Dharma. Therefore, a verse spoken in the Mahāprajñāpāramitā-śāstra says:
“The listener sits upright like one hungry and thirsty, / Single-mindedly entering into the words and meanings, / Hearing the Dharma with leaping joy, heart moved with weeping and delight: / To such a person, one may expound it.”
Therefore, he first commands them to listen, and only then promises to expound.
