淨名經集解關中疏 2.233

2.233

或現劫盡燒。天地皆洞然。眾人有常想。照令知無常。無數億眾生。俱來諸菩薩。一時到其舍。化令而佛道　三二行明大三災。水風二災文無者略。初禪內有覺觀。外有火災。二禪內有喜受。外有水災。三禪內有喘息。外有風災。四禪無災由不動故。什曰。或實燒或不實燒者。眾生見燒想即悟無常。還攝不燒也。

"Or he manifests the burning at the end of the kalpa, / Where heaven and earth are entirely ablaze; / Sentient beings harbor notions of permanence: / He illumines them, causing them to know impermanence. / Countless billions of sentient beings / And all the bodhisattvas who came along / Arrive together at their homes, / Converting them toward the Buddha path." / Part three: the two verses clarify the three great disasters. The water and wind disasters are omitted for brevity. Within the first dhyāna there are vitarka and vicāra; externally there is the fire disaster. Within the second dhyāna there is the feeling of joy; externally there is the water disaster. Within the third dhyāna there is respiration; externally there is the wind disaster. The fourth dhyāna has no disasters because it is motionless. [Kumāra]jīva says: "Whether it is an actual burning or not an actual burning, when sentient beings see the burning, they immediately awaken to impermanence; he then withdraws it so that it is not burned."
