1 What must be done, O bhikkhus, [by] one whose clothes or [hair] on the head is in flames? Now, O Bhante, what must be done by one whose clothes or [hair] on the head is in flames is to [arouse] exceeding desire, effort, endurance, exertion, zeal, mindfulness and contemplative only for quenching that [fire] on the clothes or [hair] on the head. One whose clothes or [hair] on head is in flames, O bhikkhus, having looked on with indifference, having not paid attention, ought to [arouse] exceeding desire, effort, endurance, exertion, zeal, mindfulness and contemplative for the breakthrough if one has not made the breakthrough to the four noble truths as they have come to be. Which four? The noble truth of suffering, the noble truth of the arising of suffering, the noble truth of the cessation of suffering, the noble truth of the path leading to the cessation of suffering.

2 Therefore, O bhikkhus, an endeavour should be made [to realize]: “This is suffering.” An endeavour should be made [to realize]: “This is the origination of suffering.” An endeavour should be made [to realize]: “This is the cessation of suffering.” An endeavour should be made [to realize]: “This is the path leading to the cessation of suffering.”
