涅槃經遊意 1.227

1.227

反詰云（又難）：若常住之法復有始有之義者，亦應無常之法，應無本有之義；若無常法但有始有，無本有者，則常住法但是本有，無始有也。

Turning the question back (another objection): if an eternally abiding dharma also had the meaning of newly acquired existence, then an impermanent dharma should likewise lack the meaning of original existence; if impermanent dharmas have only newly acquired existence and lack original existence, then eternally abiding dharmas would have only original existence and lack newly acquired existence.
