(Originating in Sāvatthī.)
Then the brahmin Jāṇussoṇī approached the Blessed One and exchanged greetings with him. When this courteous and friendly exchange was concluded, the brahmin Jāṇussoṇī sat down at one side. Sitting thus at one side, the brahmin Jāṇūssoṇī said this to the Blessed One:
"Does the Blessed One profess to be a brahmachari (brahmacārī)?"
"Brahmin, if one speaking rightly were to say of anyone, thus: 'He lives the perfect and pure brahmachari life, unbroken, untorn [consistent], unmixed [not altering the rules], spotless,'[1] he, brahmin, would be speaking rightly of me. For, I, brahmin, live the perfect and pure brahmachari life, unbroken, untorn [consistent], unmixed [not altering the rules], spotless."
"But, master Gotama, what is the break, the tear, the mottle, the blotch of the holy life [brahma-charya]?"[2]
"Here, brahmin, a certain ascetic or brahmin, declares himself to be a total brahmachari. For, he does not indulge in coupling [in sexual intercourse] with women. But he consents to being rubbed, massaged, bathed, and kneaded by women.[3] He relishes it, longs for it, and savours it.[4] This, brahmin, is a break, and a tear, and a mottle, and a blotch of the holy life. This, brahmin, is called one who leads the impure holy life, who is devoted to the indulgence of coupling. He is not freed from birth, decay-and-death, sorrow, lamentation, physical pain, mental pain: he is not freed from suffering, I say!
"Furthermore, brahmin, a certain ascetic or brahmin, declares himself to be a total brahmachari. Nor does he indulge in coupling with women. Nor does he consent to being rubbed, massaged, bathed, and kneaded by women. But he jokes with women, plays with them, jests with them.[5] He relishes it, longs for it, and savours it. This, brahmin, is a break, and a tear, and a mottle, and a blotch of the holy life. This, brahmin, is called one who leads the impure holy life, who is devoted to the indulgence of coupling. He is not freed from birth, decay-and-death, sorrow, lamentation, physical pain, mental pain: he is not freed from suffering, I say!
"Furthermore, brahmin, a certain ascetic or brahmin, declares himself to be a complete brahma-chari. For, he does not indulge in coupling with women. Nor does he consent to being rubbed, massaged, bathed, and kneaded by women, too. Nor does he joke, play or jest with women. But he gazes and looks on eye to eye at women.[6] He relishes it, longs for it, and savours it. This, brahmin, is a break, and a tear, and a mottle, and a blotch of the holy life.

But he sees a houselord or a houselord’s son being entertained, showered and serviced with the cords of sense-pleasures.[9] He relishes it, longs for it, and savours it.

This, brahmin, is a break, and a tear, and a mottle, and a blotch of the holy life.

"And as along as I noticed that one or other of these seven bonds of sexuality[11] unabandoned in me, to that extent, brahmin, I did not claim to be supremely awakened in the peerless full self-awakening in this world with its gods, with its Māra, with its Brahmā, this generation with its recluses and brahmins, its rulers[12] and people.
"But, brahmin, when I did not notice any of these seven bonds of sexuality unabandoned in me, to that extent, brahmin, I have claimed to be supremely awakened in the peerless full self-awakening in this world with its gods, with its Māra, with its Brahmā, this generation with its recluses and brahmins, its rulers and people.
"And the knowledge and vision arose in me, 'Unshakable is the liberation of mind. This is my last birth. There is no more rebirth here'"
When this was spoken, the brahmin Jāṇussoṇī said this to the Blessed One:
"Excellent, Master Gotama! Excellent! Master Gotama! Just as if one were to place upright what had been overturned, were to reveal what was hidden, were to show the way to one who was lost, or were to hold up a lamp in the dark so that those with eyes could see forms, in the same way, in numerous ways, has the Dharma been made clear by master Gotama. I go to tmaster Gotama for refuge, to the Dharma, and to the community of monks. May master Gotama remember us as lay followers who have gone for refuge, from this day forth, for life."
