At the city of Sāvatthī …
“Monks, there are 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, and the Noble Truth of the path that leads to the cessation of suffering. These are the Four Noble Truths. It is because the Buddha has truly realized these Four Noble Truths that the Blessed One is called ‘the liberated one, the fully enlightened Buddha.’
“Therefore, monks, you should make an effort to understand: ‘This is suffering.’ You should make an effort to understand: ‘This is the origin of suffering.’ You should make an effort to understand: ‘This is the cessation of suffering.’ You should make an effort to understand: ‘This is the path that leads to the cessation of suffering.’”
