Mahasatipatthana Sutta
v. Sacca Pabba (Section on Noble Truths)

And again, bhikkhus, a bhikkhu dwells perceiving again and again the Four Noble Truths as just the Four Noble Truths (not mine, not I, not self, but just as phenomena). And how, bhikkhus, does a bhikkhu dwell perceiving again and again the Four Noble Truths as just the Four Noble Truths? Here, (in this teaching), bhikkhus, a bhikkhu knows as it really is, “This is dukkha”; he knows as it really is, “This is the cause of dukkha”; he knows as it really is, “This is the cessation of dukkha”; he knows as it really is, “This is the path leading to the cessation of dukkha.”
