大般涅槃經集解 61.20

61.20

案僧亮曰：第七翻，不能觀身五種過患。此有五階，明五門也。此總明五門過患也。寶亮曰：此下訖金翅鳥，第二，歷別明四法也。

Sengliang states: "In the seventh turn, they cannot contemplate the five kinds of faults and perils of the body. Here there are five steps, clarifying five gates. This broadly clarifies the faults and perils of the five gates." Baoliang states: "From here down to the garuḍa bird is the second part, clarifying the four dharmas individually."
