“Good, good, mendicant! It’s good that you remember the four noble truths as I’ve taught them. Suffering is the first noble truth I’ve taught, and that’s how you should remember it. For if any ascetic or brahmin should say this: ‘What the ascetic Gotama teaches is not the first noble truth of suffering. I’ll deny this first noble truth of suffering and describe another first noble truth of suffering.’ That is not possible. The origin of suffering … The cessation of suffering … The practice that leads to the cessation of suffering is the fourth noble truth I’ve taught, and that’s how you should remember it. For if any ascetic or brahmin should say this: ‘What the ascetic Gotama teaches is not the fourth noble truth of the practice that leads to the cessation of suffering. I’ll deny this fourth noble truth of the practice that leads to the cessation of suffering and describe another fourth noble truth of the practice that leads to the cessation of suffering.’ That is not possible. That’s how you should remember the four noble truths as I’ve taught them.

That’s why you should practice meditation …”
