涅槃經遊意 1.228

1.228

又，常住之法具二義者，何因所出？本有之義須了因而出，始有之義復為何所感？若無別因，則應無別有；既有二有，則便兩因，若從生因則無常也。

Furthermore, if an eternally abiding dharma possesses both meanings, from what causes do they arise? The meaning of original existence requires a revealing cause to emerge; from what is the meaning of newly acquired existence induced? If there is no separate cause, there should be no separate existence; since there are two existences, there would be two causes, and if it derives from a producing cause, it is impermanent.
