宏智禪師廣錄 4.246

4.246

示眾舉僧問風穴。一切諸佛。及阿耨多羅三藐三菩提法。皆從此經出。如何是此經。穴云低聲。僧云。如何受持。穴云莫染污。師云。來問此經。低聲大千卷自塵中出。三世佛從口裏生。天得一以清。地得一以寧。空無依兮谷不盈。摩訶般若波羅密。落日漁樵歌太平。

Instructing the assembly, he brought up: A monk asked Fengxue: "All the Buddhas and the Dharma of anuttarasamyaksaṃbodhi come forth from this sūtra. What is this sūtra?"
Fengxue said: "Lower your voice."
The monk said: "How to uphold it?"
Fengxue said: "Do not defile it."
The Master said: "Coming to ask about this sūtra: 'Lower your voice'—scrolls of the great chiliocosm emerge by themselves from within a dust mote, and the Buddhas of the three periods are born from the mouth. Heaven, by attaining the One, becomes clear; Earth, by attaining the One, becomes tranquil. Space has nothing to rely on, and the valleys do not overflow. Mahāprajñāpāramitā—the setting sun, fishermen and woodcutters singing of the peaceful reign."
