仁王護國般若波羅蜜多經疏 3.67

3.67

解曰：梵釋天龍者，梵謂梵王，通四禪也。釋謂帝釋，忉利主也，舉此攝餘諸天處也。此二自在，勝故標也。言天龍者，八部眾也。諸有情等者，除前所明餘界趣也。尚皆殄滅者，明無常也。何況此身者，界無大小、情無勝劣，彼皆殄滅，何況此身。示無常矣。從此第二明諸法苦。於中分二：且初第一明列諸苦。

Exposition: Regarding 'the gods, nāgas, Brahmā, and Śakra,' Brahmā refers to the Brahmā kings, encompassing the four dhyānas. Śakra refers to Śakra Devendra, the lord of Trāyastriṃśa; mentioning these subsumes the other heavenly realms. These two have mastery and are supreme, hence they are specified. 'Gods and nāgas' refers to the assembly of the eight classes. 'All sentient beings' refers to the other realms and destinies apart from those explained before. 'Are completely extinguished' clarifies their impermanence. 'How much more so this body': whether realms are large or small, or sentient beings are superior or inferior, they are all completely destroyed; how much more so this body? It demonstrates impermanence. From here, the second part explains that all phenomena are suffering. In this there are two parts: first, enumerating the various sufferings.
