“Bhikkhus, if anyone should speak thus: ‘Without having made the breakthrough to the noble truth of suffering as it really is, without having made the breakthrough to the noble truth of the origin of suffering as it really is, without having made the breakthrough to the noble truth of the cessation of suffering as it really is, without having made the breakthrough to the noble truth of the way leading to the cessation of suffering as it really is, I will completely make an end to suffering’—this is impossible.
“Just as, bhikkhus, if anyone should speak thus, ‘Without having built the lower storey of a peaked house, I will erect the upper storey,’ this would be impossible; so too, if anyone should speak thus: ‘Without having made the breakthrough to the noble truth of suffering as it really is… I will completely make an end to suffering’—this is impossible.
“But, bhikkhus, if anyone should speak thus: ‘Having made the breakthrough to the noble truth of suffering as it really is, having made the breakthrough to the noble truth of the origin of suffering as it really is, having made the breakthrough to the noble truth of the cessation of suffering as it really is, having made the breakthrough to the noble truth of the way leading to the cessation of suffering as it really is, I will completely make an end to suffering’—this is possible.
“Just as, bhikkhus, if anyone should speak thus: ‘Having built the lower storey of a peaked house, I will erect the upper storey,’ this would be possible; so too, if anyone should speak thus: ‘Having made the breakthrough to the noble truth of suffering as it really is… I will completely make an end to suffering’—this is possible.
“Therefore, bhikkhus, an exertion should be made to understand: ‘This is suffering.’… An exertion should be made to understand: ‘This is the way leading to the cessation of suffering.’”
