大般涅槃經義記 8.289

8.289

第十一中，以僧常住無作佛義難破有性。「如佛先說僧寶是常」舉佛先言。「如其常者則非無常」以理審定，「非無常」下難破得果。「僧若常」下，以不得果難破有性。

In the eleventh, he uses the permanent abiding of the Saṅgha and its having no sense of becoming a buddha to interrogate and refute having a nature. "As the Buddha previously spoke of the Saṅgha Jewel being permanent" cites the Buddha's earlier words. "If it is permanent, then it is not impermanent": he examines and establishes it by principle. From "Not impermanent..." onward, he interrogates and refutes the attainment of the fruit. From "If the Saṅgha is permanent..." onward, he interrogates and refutes having a nature on the grounds that it does not attain the fruit.
