大般涅槃經集解 6.57

6.57

案道生曰：縱依昔教得解，而於餘教未了也。僧亮曰：更為佛作過也。若慈必救重，應捨聖從凡者，凡夫計常，故佛應現滅。若爾，我有半病，故以瘧為譬，佛應救之也。法瑤曰：此譬明無常涅槃也。雖免分段，而變易猶在，為半日病也。寶亮曰：瘧是寒熱之病，明我等九十八使都未除也。智秀曰：佛除我麁煩惱，即日不發；而細者根本猶在未去，如瘧之未發也。

Daosheng states: Even if they attain understanding according to the past teaching, they are still not clear about the other teachings. Sengliang states: This again attributes fault to the Buddha. If compassion must rescue the grave, and should leave the holy to attend to the ordinary, then ordinary persons cling to permanence, and so the Buddha should manifest extinction. If that is so, we have a half-[cured] illness, hence using malaria as an analogy, and the Buddha should save us. Fayao states: This analogy clarifies impermanent nirvāṇa. Although they have escaped fragmented [samsāric death], death by inconceivable transformation still remains; this is the half-day illness. Baoliang states: Malaria is a sickness of alternating cold and fever; it clarifies that our ninety-eight proclivities have not all been eliminated. Zhixiu states: The Buddha eliminated our coarse afflictions so that they do not arise on that day; yet the subtle roots still remain unremoved, like malaria that has not yet flared up.
