Lokasutta

“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.

“Mendicants, there are these four noble truths. What four? The noble truths of suffering, the origin of suffering, the cessation of suffering, and the practice that leads to the cessation of suffering. In this world with its gods, Māras, and divinities, this population with its ascetics and brahmins, its gods and humans, the Realized One is the Noble One. That’s why they’re called ‘noble truths’.

Tasmātiha, bhikkhave, ‘idaṁ dukkhan’ti yogo karaṇīyo …pe… ‘ayaṁ dukkhanirodhagāminī paṭipadā’ti yogo karaṇīyo”ti. Aṭṭhamaṁ.

That’s why you should practice meditation …”
