“Bhikkhus, this is the forerunner and precursor of the rising of the sun, that is, the dawn. So too, bhikkhus, for a bhikkhu this is the forerunner and precursor of the breakthrough to the Four Noble Truths as the really are, that is, right view. It is to be expected that a bhikkhu with right view will understand as it really is: ‘This is suffering.’… ‘This is 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.’”
