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.

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.
