Vuttañhetaṁ bhagavatā vuttamarahatāti me sutaṁ:
This was said by the Blessed One, said by the Awakened One, as I have heard:
“Tathā tathā, bhikkhave, bhikkhu upaparikkheyya yathā yathāssa upaparikkhato bahiddhā cassa viññāṇaṁ avikkhittaṁ avisaṭaṁ ajjhattaṁ asaṇṭhitaṁ anupādāya na paritasseyya. Bahiddhā, bhikkhave, viññāṇe avikkhitte avisaṭe sati ajjhattaṁ asaṇṭhite anupādāya aparitassato āyatiṁ jātijarāmaraṇadukkhasamudayasambhavo na hotī”ti.
“A bhikkhu should examine in such a way that, as he examines, his consciousness is unscattered and undispersed externally, not fixated internally, and by not grasping, he is unperturbed. When consciousness is unscattered and undispersed externally, not fixated internally, and one is unperturbed by not grasping, there is no future arising of birth, old age, death, and suffering.” [1]
Etamatthaṁ bhagavā avoca. Tatthetaṁ iti vuccati:
The Blessed One spoke on this matter. In this regard, it is said:
“Sattasaṅgappahīnassa,
netticchinnassa bhikkhuno;
Vikkhīṇo jātisaṁsāro,
natthi tassa punabbhavo”ti.
“For a bhikkhu who has abandoned the seven bonds,
who has severed craving,
who has exhausted birth in cyclic existence,
for him, there is no more renewed existence.”
Ayampi attho vutto bhagavatā, iti me sutanti.
This matter too was spoken by the Blessed One, as I have heard.
