The Second Discourse on the Sun
1108.
"As long as, monks, the moon and sun do not arise in the world, there is no manifestation of great light, of great radiance.
Then there is deep darkness, blinding darkness.
Night and day are not discernible, months and fortnights are not discernible, seasons and years are not discernible.
"But when, monks, the moon and sun arise in the world, then there is manifestation of great light, of great radiance. Then there is no darkness, no blinding darkness. Then night and day are discernible, months and fortnights are discernible, seasons and years are discernible. So too, monks, as long as a Truth-finder does not arise in the world, a Worthy One, a Perfectly Enlightened One, there is no manifestation of great light, of great radiance. Then there is deep darkness, blinding darkness. There is no declaring, teaching, describing, establishing, revealing, analysing, and making manifest of the four noble truths.
"But when, monks, a Truth-finder arises in the world, a Worthy One, a Perfectly Enlightened One, then there is manifestation of great light, of great radiance. Then there is no deep darkness, no blinding darkness. Then there is declaring, teaching, describing, establishing, revealing, analysing, and making manifest of the four noble truths. Which four? The noble truth of suffering, etc. the noble truth of the practice leading to the cessation of suffering.
"Therefore, monks, exertion is to be done regarding 'This is suffering', etc. exertion is to be done regarding 'This is the practice leading to the cessation of suffering.'" The eighth.
