“Bhikkhus, there are these Four Noble Truths. What four? The noble truth of suffering, the noble truth of the origin of suffering, the noble truth of the cessation of suffering, the noble truth of the way leading to the cessation of suffering.
“And what, bhikkhus, is the noble truth of suffering? It should be said: the six internal sense bases. What six? The eye base … the mind base. This is called the noble truth of suffering.”
The rest of the sutta is identical with §13.
