The Discourse on the Peak
223.
Thus have I heard -
On one occasion the Blessed One was dwelling at Sāvatthī in Jeta's Grove, Anāthapiṇḍika's park.
There the Blessed One addressed the monks thus:
"Monks."
"Venerable sir," those monks assented to the Blessed One.
The Blessed One said this:
"Just as, monks, whatever rafters there are of a pinnacle chamber, all of them go to the pinnacle, converge at the pinnacle, and by the uprooting of the pinnacle, all of them are uprooted;
so too, monks, whatever unwholesome mental states there are, all of them are rooted in ignorance, converge in ignorance, and by the uprooting of ignorance, all of them are uprooted.
Therefore, monks, you should train thus -
'We will dwell diligent.'
Thus indeed, monks, should you train."
The first.
