Tena samayena buddho bhagavā sāvatthiyaṁ viharati jetavane anāthapiṇḍikassa ārāme.At one time when the Buddha was staying at Sāvatthī in Anāthapiṇḍika’s Monastery, Tena kho pana samayena sambahulā bhikkhuniyo aciravatiyā nadiyā vesiyāhi saddhiṁ naggā ekatitthe nahāyanti.
nahāyanti → nhāyanti (pts) | sambahulā → mahāva. 350 (cck note)a number of nuns were bathing naked at a ford in the river Aciravatī together with sex workers. Vesiyā tā bhikkhuniyo uppaṇḍesuṁ—
uppaṇḍesuṁ kiṁ nu → upphaṇḍesuṁ kinnu (sya-all)The sex workers teased them, “kiṁ nu kho nāma tumhākaṁ, ayye, daharānaṁ brahmacariyaṁ ciṇṇena, nanu nāma kāmā paribhuñjitabbā.
tumhākaṁ, ayye, daharānaṁ → daharānaṁ daharānaṁ (bj) | ayye → ayye daharānaṁ (bj) | daharānaṁ → ayye daharānaṁ (bj: machasaṁ) | daharānaṁ → daharānaṁ daharānaṁ (cck: sī.) | ciṇṇena → Comp. Mahāvagga VIII.15.10. Read in the Mahāvagga, ciṇṇena instead of ciṇṇe (cikkena, the Berlin MS.). (pts note)“Venerables, why practice the spiritual life when you’re still young? Why not enjoy worldly pleasures? Yadā jiṇṇā bhavissatha tadā brahmacariyaṁ carissatha.You can practice the spiritual life when you’re old. Evaṁ tumhākaṁ ubho atthā pariggahitā bhavissantī”ti.
evaṁ → evañca (bj) | atthā → antā (pts) | evañca → evaṁ (bj: machasaṁ); evañce (bj: __sī2__) | antā → ubho atthā AB. Correct, ubho antā (Mahāv.1.c.). (pts note)In this way you’ll get the benefits of both.” Bhikkhuniyo vesiyāhi uppaṇḍiyamānā maṅkū ahesuṁ.
uppaṇḍiyamānā → upphaṇḍiyamānā (sya-all) | maṅkū → maṅku (bj: sīmu1, sīmu2, __sī2__)The nuns felt humiliated.

Atha kho tā bhikkhuniyo upassayaṁ gantvā bhikkhunīnaṁ etamatthaṁ ārocesuṁ.They then went to the nunnery and told the nuns what had happened. Bhikkhuniyo bhikkhūnaṁ etamatthaṁ ārocesuṁ.
etamatthaṁ → (pts)The nuns told the monks, Bhikkhū bhagavato etamatthaṁ ārocesuṁ.
etamatthaṁ → (pts)who in turn told the Buddha. Atha kho bhagavā etasmiṁ nidāne etasmiṁ pakaraṇe dhammiṁ kathaṁ katvā bhikkhū āmantesi—Soon afterwards the Buddha gave a teaching and addressed the monks: “tena hi, bhikkhave, bhikkhunīnaṁ sikkhāpadaṁ paññapessāmi dasa atthavase paṭicca—
paññapessāmi → paññāpessāmi (bj, sya-all, pts)“Well then, monks, I will lay down a training rule for the nuns for the following ten reasons: saṅghasuṭṭhutāya …pe…for the well-being of the Sangha … vinayānuggahāya.for supporting the training. Evañca pana, bhikkhave, bhikkhuniyo imaṁ sikkhāpadaṁ uddisantu—And, monks, the nuns should recite this training rule like this:

“Yā pana bhikkhunī naggā nahāyeyya, pācittiyan”ti.
nahāyeyya pācittiyanti → nhāyeyya pācittiyan ti (pts)‘If a nun bathes naked, she commits an offense entailing confession.’”

Yā panātiA:

yā yādisā …pe…whoever …

bhikkhunītiNun:

…pe… ayaṁ imasmiṁ atthe adhippetā bhikkhunīti.… The nun who has been given the full ordination in unanimity by both Sanghas through a legal procedure consisting of one motion and three announcements that is irreversible and fit to stand—this sort of nun is meant in this case.

Naggā nahāyeyyāti
nahāyeyyāti → nhāyeyyā ti (pts)Bathes naked:

anivatthā vā apārutā vā nahāyati, payoge dukkaṭaṁ.
nahāyati → nhāyati (pts)if she bathes without wearing a sarong or an upper robe, then for the effort there is an act of wrong conduct. Nahānapariyosāne āpatti pācittiyassa.
nahānapariyosāne → nhānapariyosāne (pts)At the end of the bath, she commits an offense entailing confession.

Anāpatti—There is no offense: acchinnacīvarikāya vā naṭṭhacīvarikāya vā,
vā → (bj) | naṭṭhacīvarikāya → acchinnacīvarikāya vā naṭṭhacīvarikāya vā (bj: sīmu1)if her robes have been stolen or lost; āpadāsu,if there is an emergency; ummattikāya,if she is insane; ādikammikāyāti.if she is the first offender.

Paṭhamasikkhāpadaṁ niṭṭhitaṁ.The first training rule is finished.
