1Then a mendicant went up to the Buddha … and asked him:

“Sir, they speak of ‘a witless idiot’. How is a witless idiot defined?”

“Mendicant, they’re called a witless idiot because they haven’t developed and cultivated the seven awakening factors. What seven? The awakening factors of mindfulness, investigation of principles, energy, rapture, tranquility, immersion, and equanimity. They’re called a witless idiot because they haven’t developed and cultivated these seven awakening factors.”

1Atha kho aññataro bhikkhu yena bhagavā tenupasaṅkami … pe … ekamantaṁ nisinno kho so bhikkhu bhagavantaṁ etadavoca:

"‘Duppañño eḷamūgo, duppañño eḷamūgo’ti, bhante, vuccati. Kittāvatā nu kho, bhante, ‘duppañño eḷamūgo’ti vuccatī"ti?

"Sattannaṁ kho, bhikkhu, bojjhaṅgānaṁ abhāvitattā abahulīkatattā ‘duppañño eḷamūgo’ti vuccati. Katamesaṁ sattannaṁ? Satisambojjhaṅgassa … pe … upekkhāsambojjhaṅgassa – imesaṁ kho, bhikkhu, sattannaṁ bojjhaṅgānaṁ abhāvitattā abahulīkatattā ‘duppañño eḷamūgo’ti vuccatī"ti.

Catutthaṁ.
