“Bhikkhus, if one’s clothes or head were ablaze, what should be done about it?”
“Venerable sir, if one’s clothes or head were ablaze, to extinguish one’s blazing clothes or head one should arouse extraordinary desire, make an extraordinary effort, stir up zeal and enthusiasm, be unremitting, and exercise mindfulness and clear comprehension.”
“Bhikkhus, one might look on equanimously at one’s blazing clothes or head, paying no attention to them, but so long as one has not made the breakthrough to the Four Noble Truths as they really are, in order to make the breakthrough one should arouse extraordinary desire, make an extraordinary effort, stir up zeal and enthusiasm, be unremitting, and exercise mindfulness and clear comprehension. What four? The noble truth of suffering … the noble truth of the way leading to the cessation of suffering.
“Therefore, bhikkhus, an exertion should be made to understand: ‘This is suffering.’… An exertion should be made to understand: ‘This is the way leading to the cessation of suffering.’”
