1"Bhikkhus, these are these Four Noble Truths. What four?

The noble truth of suffering, the noble truth of the origin of suffering, the noble truth of the cessation of suffering, the noble truth of the way leading to the cessation of suffering.

In this world, with its devas, Māra, and Brahma, in this generation with its ascetics and brahmins, its devas and humans, the Tathāgata is the noble one. Therefore they are called noble truths.

2"Therefore, bhikkhus, an exertion should be made to understand: ‘This is suffering.’[n.376] Tasmātiha bhikkhave idaṁ dukkhan ti yogo karaṇīyo. Spk: Since a concentrated bhikkhu understands the Four Noble Truths as they really are, therefore you should make an exertion to become concentrated in order to understand the four truths as they really are. And since the round of existence increases for those who do not penetrate them, but stops increasing from the time they are penetrated, therefore you should make an exertion to understand them, thinking, "Let the round not increase for us."
An exertion should be made to understand: ‘This is the origin of suffering.’
An exertion should be made to understand: ‘This is the cessation of suffering.’
An exertion should be made to understand: ‘This is the way leading to the cessation of suffering.’"sn.v.436

1"Cattārimāni, bhikkhave, ariyasaccāni. Katamāni cattāri?

Dukkhaṁ ariyasaccaṁ, dukkhasamudayaṁ ariyasaccaṁ, dukkhanirodhaṁ ariyasaccaṁ, dukkhanirodhagāminī paṭipadā ariyasaccaṁ.

Sadevake loke samārake sabrahmake sassamaṇabrāhmaṇiyā pajāya sadevamanussāya tathāgato ariyo; tasmā ‘ariyasaccānī’ti vuccanti.

2Tasmātiha, bhikkhave, ‘idaṁ dukkhan’ti yogo karaṇīyo … pe … ‘Ayaṁ dukkhanirodhagāminī paṭipadā’ti yogo karaṇīyo"ti.

Aṭṭhamaṁ.
