Tena samayena buddho bhagavā sāvatthiyaṁ viharati jetavane anāthapiṇḍikassa ārāme.At one time the Buddha was staying at Sāvatthī in the Jeta Grove, Anāthapiṇḍika’s Monastery. Tena kho pana samayena bhagavatā bhikkhunīnaṁ udakasāṭikā anuññātā hoti.
bhikkhunīnaṁ → mahāva. 351 (cck note)At that time the Buddha had allowed bathing robes for the nuns. Chabbaggiyā bhikkhuniyo— “bhagavatā udakasāṭikā anuññātā”ti appamāṇikāyo udakasāṭikāyo dhāresuṁ.
dhāresuṁ → dhārenti (bj) | dhārenti → dhāresuṁ (bj: machasaṁ) | dhāresuṁ → dhārenti (cck: pāci. 531-545)Knowing this, the nuns from the group of six wore bathing robes of inappropriate size. Puratopi pacchatopi ākaḍḍhantā āhiṇḍanti.
pacchatopi → pacchitopi (bj) | āhiṇḍanti → āhiṇḍantā (sya-all) | ākaḍḍhantā → kaḍḍhantā (bj: sīmu2)As they were walking about, they were dragging them along, both in front and behind.

Yā tā bhikkhuniyo appicchā …pe… tā ujjhāyanti khiyyanti vipācenti—
khiyyanti → khīyanti (bj, sya-all)The nuns of few desires complained and criticized them, “kathañhi nāma chabbaggiyā bhikkhuniyo appamāṇikāyo udakasāṭikāyo dhāressantī”ti …pe…“How can the nuns from the group of six wear such bathing robes?” … “saccaṁ kira, bhikkhave, chabbaggiyā bhikkhuniyo appamāṇikāyo udakasāṭikāyo dhārentī”ti?
appamāṇikāyo udakasāṭikāyo → (pts)“Is it true, monks, that the nuns from the group of six do this?”

“Saccaṁ, bhagavā”ti.“It’s true, sir.”

Vigarahi buddho bhagavā …pe…The Buddha rebuked them … kathañhi nāma, bhikkhave, chabbaggiyā bhikkhuniyo appamāṇikāyo udakasāṭikāyo dhāressanti.

Netaṁ, bhikkhave, appasannānaṁ vā pasādāya …pe…This will affect people’s confidence …” … evañca pana, bhikkhave, bhikkhuniyo imaṁ sikkhāpadaṁ uddisantu—“And, monks, the nuns should recite this training rule like this:

“Udakasāṭikaṁ pana bhikkhuniyā kārayamānāya pamāṇikā kāretabbā. Tatridaṁ pamāṇaṁ—dīghaso catasso vidatthiyo, sugatavidatthiyā; tiriyaṁ dve vidatthiyo. Taṁ atikkāmentiyā chedanakaṁ pācittiyan”ti.

(pts note)‘If a nun is having a bathing robe made, it should be made the right size. This is the right size: four standard handspans long and two wide. If it exceeds that, it is to be cut down, and she commits an offense entailing confession.’”

Udakasāṭikā nāma

vidatthiyo → vidatthithiyo (bj)This is the right size: four standard handspans long and two wide. Taṁ atikkāmetvā karoti vā kārāpeti vā, payoge dukkaṭaṁ.If she makes one or has one made that exceeds that, then for the effort there is an act of wrong conduct. Paṭilābhena chinditvā pācittiyaṁ desetabbaṁ.When she gets it, it is to be cut down, and she is then to confess an offense entailing confession.

Attanā vippakataṁ attanā pariyosāpeti, āpatti pācittiyassa.If she finishes what she began herself, she commits an offense entailing confession. Attanā vippakataṁ parehi pariyosāpeti, āpatti pācittiyassa.
āpatti pācittiyassa → (pts)If she has others finish what she began herself, she commits an offense entailing confession. Parehi vippakataṁ attanā pariyosāpeti, āpatti pācittiyassa.

Aññassatthāya karoti vā kārāpeti vā, āpatti dukkaṭassa.If she makes one or has one made for the benefit of someone else, she commits an offense of wrong conduct. Aññena kataṁ paṭilabhitvā paribhuñjati, āpatti dukkaṭassa.If she gets one that was made by someone else and then uses it, she commits an offense of wrong conduct.

Anāpatti—There is no offense: pamāṇikaṁ karoti,if she makes it the right size; ūnakaṁ karoti,if she makes it smaller than the right size; aññena kataṁ pamāṇātikkantaṁ paṭilabhitvā chinditvā paribhuñjati,if she gets one made by someone else that exceeds the right size and she cuts it down before using it; vitānaṁ vā bhūmattharaṇaṁ vā sāṇipākāraṁ vā bhisiṁ vā bibbohanaṁ vā karoti,
bhūmattharaṇaṁ → bhumattharaṇaṁ (bj, sya-all, pts) | bibbohanaṁ → bimbohanaṁ (sya-all, pts) | bhumattharaṇaṁ → bhūmattharaṇaṁ (bj: machasaṁ)if she makes a canopy, a floor cover, a cloth screen, a mattress, or a pillow; ummattikāya,if she is insane; ādikammikāyāti.if she is the first offender.
