大般涅槃經義記 8.279

8.279

就初句中，師子初言「乳中無酪，麻無油」等，牒佛上來無性之言。「如佛先」下，破佛前來有性之語。「何以故」下，自立無義，先徵、後辯。「人天無性故可作」等，舉近類遠。「菩薩以業得菩提」等，將遠類近。

In the first clause, Siṃhanāda first says, "There is no curd in milk, no oil in sesame," and so forth, citing the Buddha's previous words on the lack of nature. From "As the Buddha previously..." onward, he refutes the Buddha's previous words about an existent nature. From "Why?" onward, he establishes his own thesis of non-existence, first interrogating, then analyzing. "Humans and devas have no [fixed] nature, hence they can become [different states]" and so forth adduces the near to analogize the far. "A bodhisattva obtains bodhi through karma" and so forth takes the far to analogize the near.
