"Bhikkhus, there are these four noble truths. What four? The Noble Truth of suffering, the Noble Truth of the arising of suffering, the Noble Truth of the ending of suffering, the Noble Truth of the way of practice leading to the ending of suffering. These, bhikkhus are the Four Noble Truths.

Bhikkhus, regarding these Four Noble Truths, there is a Noble Truth that should be fully understood, a Noble Truth that should be abandoned, a Noble Truth that should be personally experienced, and a Noble Truth that should be developed.

And what bhikkhus, is the Noble Truth that should be fully understood? It is the Noble Truth of suffering, bhikkhus, that should be fully understood. What is the Noble Truth that should be abandoned? It is the Noble Truth of the arising of suffering that should be abandoned. What is the Noble Truth should be realized? It is the Noble Truth of the ending of suffering that should be realized. What is the Noble Truth that should be developed? It is the Noble Truth of the way of practice leading to the ending of suffering that should be developed.

Therefore, bhikkhus, effort should be made to fully understand: 'This is suffering'; effort should be made to fully understand: 'This is the arising of suffering'; effort should be made to fully understand: 'This is the ending of suffering'; effort should be made to fully understand: 'This is the way of practice leading to the ending of suffering.'""
