Saddhammappatirūpakasutta
Evaṁ me sutaṁ— ekaṁ samayaṁ bhagavā sāvatthiyaṁ viharati jetavane anāthapiṇḍikassa ārāme. Atha kho āyasmā mahākassapo yena bhagavā tenupasaṅkami; upasaṅkamitvā bhagavantaṁ abhivādetvā ekamantaṁ nisīdi. Ekamantaṁ nisinno kho āyasmā mahākassapo bhagavantaṁ etadavoca: “ko nu kho, bhante, hetu ko paccayo, yena pubbe appatarāni ceva sikkhāpadāni ahesuṁ bahutarā ca bhikkhū aññāya saṇṭhahiṁsu? Ko pana, bhante, hetu ko paccayo, yenetarahi bahutarāni ceva sikkhāpadāni appatarā ca bhikkhū aññāya saṇṭhahantī”ti? “Evañcetaṁ, kassapa, hoti sattesu hāyamānesu saddhamme antaradhāyamāne, bahutarāni ceva sikkhāpadāni honti appatarā ca bhikkhū aññāya saṇṭhahanti. Na tāva, kassapa, saddhammassa antaradhānaṁ hoti yāva na saddhammappatirūpakaṁ loke uppajjati. Yato ca kho, kassapa, saddhammappatirūpakaṁ loke uppajjati, atha saddhammassa antaradhānaṁ hoti.
The Counterfeit of the True Teaching
So I have heard. At one time the Buddha was staying near Sāvatthī in Jeta’s Grove, Anāthapiṇḍika’s monastery. Then Venerable Mahākassapa went up to the Buddha, bowed, sat down to one side, and said to him: “What is the cause, sir, what is the reason why there used to be fewer training rules but more enlightened mendicants? And what is the cause, what is the reason why these days there are more training rules and fewer enlightened mendicants?” “That’s how it is, Kassapa. When sentient beings are in decline and the true teaching is disappearing there are more training rules and fewer enlightened mendicants. The true teaching doesn’t disappear as long as the counterfeit of the true teaching hasn’t appeared in the world. But when the counterfeit of the true teaching appears in the world then the true teaching disappears.
