Third, the principle of realization and establishment (upapattisādhana-yukti): where it says 'due to the three pramāṇas, truly observing,' and so forth: first, verifying the impermanence of the aggregates based on sacred teaching (āptāgama), because the sacred teaching states that the aggregates arise from conditions and are all impermanent; second, verifying the impermanence of the aggregates based on direct perception (pratyakṣa), because, relying on concentration, one generates the knowledge of suffering and impermanence and verifies the impermanence of the aggregates; third, verifying the impermanence of the aggregates by inference (anumāna), as when establishing against the Sāṃkhya that sound is impermanent because it is produced from conditions, like lightning. Master Ji says: It was previously called 'words of the noble' (āptavacana); now it is called 'supreme teaching' (āptāgama), meaning the ultimate teaching, for by virtue of its principle being ultimate, whether internal or external [to Buddhism], it is called the supreme teaching. What was previously called 'words of the noble' was not like this: among the thirty-two kinds of speech, there are sixteen kinds of noble speech, so why must it be the Buddha's words to be named 'noble speech'? In terms of characteristics, the noble are the Buddhas, bodhisattvas, and so forth; now calling it 'supreme teaching' makes no restrictive distinction among characteristics.
