This was said by the Buddha, the Perfected One: that is what I heard. Vuttañhetaṁ bhagavatā vuttamarahatāti me sutaṁ:

“Mendicants, there are these three faculties. “Tīṇimāni, bhikkhave, indriyāni. What three? Katamāni tīṇi? The faculty of understanding that enlightenment is imminent. The faculty of enlightenment. The faculty of one who is enlightened. Anaññātaññassāmītindriyaṁ, aññindriyaṁ, aññātāvindriyaṁ—These are the three faculties.” imāni kho, bhikkhave, tīṇi indriyānī”ti.

The Buddha spoke this matter. Etamatthaṁ bhagavā avoca. On this it is said: Tatthetaṁ iti vuccati:

“As a trainee trains, “Sekhassa sikkhamānassa, following the straight road, ujumaggānusārino; first they know about ending; Khayasmiṁ paṭhamaṁ ñāṇaṁ, enlightenment follows without delay. tato aññā anantarā.

Then the knowledge comes Tato aññāvimuttassa, to such a one, freed through enlightenment, ñāṇaṁ ve hoti tādino; with the end of the fetters of continued existence: Akuppā me vimuttīti, ‘My freedom is unshakable.’ bhavasaṁyojanakkhayā.

Accomplished in the faculties, Sa ve indriyasampanno, peaceful, in love with the state of peace, santo santipade rato; they bear their final body, Dhāreti antimaṁ dehaṁ, having vanquished Māra with his legions.” jetvā māraṁ savāhinin”ti.

This too is a matter that was spoken by the Blessed One: that is what I heard. Ayampi attho vutto bhagavatā, iti me sutanti.
