Khandhasutta
Sāvatthinidānaṁ. “Rūpaṁ, bhikkhave, aniccaṁ vipariṇāmi aññathābhāvi; vedanā aniccā vipariṇāmī aññathābhāvī; saññā … saṅkhārā aniccā vipariṇāmino aññathābhāvino; viññāṇaṁ aniccaṁ vipariṇāmi aññathābhāvi. Yo, bhikkhave, ime dhamme evaṁ saddahati adhimuccati, ayaṁ vuccati saddhānusārī, okkanto sammattaniyāmaṁ, sappurisabhūmiṁ okkanto, vītivatto puthujjanabhūmiṁ; abhabbo taṁ kammaṁ kātuṁ, yaṁ kammaṁ katvā nirayaṁ vā tiracchānayoniṁ vā pettivisayaṁ vā upapajjeyya; abhabbo ca tāva kālaṁ kātuṁ yāva na sotāpattiphalaṁ sacchikaroti.
The Aggregates
At Sāvatthī. “Mendicants, form is impermanent, decaying, and perishing. Feeling, perception, choices, and consciousness are impermanent, decaying, and perishing. Someone who has faith and confidence in these teachings is called a follower by faith. They’ve stepped into the sure path, they’ve stepped into the level of the true person, and they’ve passed beyond the level of the untrue person. They can’t do any deed which would make them be reborn in hell, the animal realm, or the ghost realm. They can’t die without realizing the fruit of stream-entry.
