Thus have I heard—At one time, the Blessed One was dwelling at Sāvatthi, in Jeta‘s Grove, Anāthapiṇḍika’s Park.
There, the Blessed One addressed the bhikkhus: “Bhikkhus.”
“Venerable sir,” those bhikkhus replied to the Blessed One. The Blessed One said this:
“Bhikkhus, just as whatever |rafters::support beams, wooden framework of a thatched roof [gopānasī]| there are in a building with the peaked roof, all of them point towards the peak, |converge upon::unite, meet, connect [samosaraṇa]| at the peak, and are removed together with the removal of the peak — so too, bhikkhus, whatever unwholesome qualities there are, all of them have ignorance as their root, converge upon ignorance, and are eradicated with the |eradication::extermination, destruction [samugghāta]| of ignorance.
Therefore, bhikkhus, you should train yourselves thus: ‘We will dwell |diligently::doing one’s work or duty well, with alertness, carefulness and care [appamatta]|.’ Thus, bhikkhus, you should train yourselves.”
