大般涅槃經義記 6.111

6.111

下就設難，難辭有二：一明此三常故無得、二「夫道者非色」已下明此三法無相無得。前中四句：一明此三得則無常；二「何以」下明此三法常故無得，先徵、後解，解中初法、後以喻顯；三「如世物」下成向初句明得無常，先喻、後合；四「法若常」下成向後句明常無得，先法、後喻。第二無相無得難中，先明道法無相無得，後類菩提及與涅槃。

Next, he sets forth the objection. The phrasing of the objection has two parts: First, it explains that because these three are eternal, there is no attainment; second, from "Now, as for the Path, it is not form" onward, it explains that these three dharmas are markless and without attainment. In the former, there are four sentences: First, it explains that if these three are attained, then they are impermanent; second, from "Why?" onward, it explains that because these three dharmas are eternal, there is no attainment, first inquiring and then explaining, where the explanation first presents the dharma and then illustrates it with an analogy; third, from "Just as worldly things" onward, it establishes the preceding first sentence explaining that what is attained is impermanent, first by analogy and then by application; fourth, from "If a dharma were eternal" onward, it establishes the preceding latter sentence explaining that what is eternal is without attainment, first by dharma and then by analogy. In the second objection concerning being markless and without attainment, it first explains that the dharma of the Path is markless and without attainment, and then extends this by analogy to bodhi and nirvāṇa.
