[1693] "Good, good, bhikkhu! It is good indeed, bhikkhu, that you remember the four noble truths (ariyasacca) taught by me. Suffering (dukkha), bhikkhu, has been taught by me as the first noble truth; remember it thus. For if any ascetic or brahmin, bhikkhu, should speak thus: 'This is not the first noble truth of suffering that was taught by the ascetic Gotama; having rejected this first noble truth of suffering, I shall make known another first noble truth of suffering' — such a case is impossible. The origin of suffering, bhikkhu … The cessation of suffering, bhikkhu … The way of practice leading to the cessation of suffering, bhikkhu, has been taught by me as the fourth noble truth; remember it thus. For if any ascetic or brahmin, bhikkhu, should speak thus: 'This is not the fourth noble truth of the way of practice leading to the cessation of suffering that was taught by the ascetic Gotama; having rejected this fourth noble truth of the way of practice leading to the cessation of suffering, I shall make known another fourth noble truth of the way of practice leading to the cessation of suffering' — such a case is impossible. Thus, bhikkhu, should you remember the four noble truths taught by me. Therefore, bhikkhu, effort should be made [to understand]: 'This is suffering' … effort should be made [to understand]: 'This is the way of practice leading to the cessation of suffering.'"
