2.391

或有清淨佛土寂寞無言無說無示無識無作無為而作佛事　肇曰。有真淨土純法身菩薩外無言說。內無情識。寂寞無為而超悟。事外非是言情所能稱述。此佛事之上也。

"Or there are pure Buddha-lands that are silent and quiescent, without words, without preaching, without indication, without consciousness, without action, and unconditioned, which thus perform the Buddha's work." Sengzhao says: "There are true pure lands of pure dharmakāya bodhisattvas where externally there is no speech, and internally there is no emotional consciousness; quiescent and unconditioned, they transcend and awaken. Beyond ordinary affairs, this is not something words or emotions can describe. This is the supreme form of the Buddha's work."
