“Udakasuddhikaṃ pana bhikkhuniyā ādiyamānāya dvaṅ­gula­pabba­paramaṃ ādātabbaṃ. Taṃ atikkāmentiyā pācittiyan”ti. (5:60)

Udakasuddhikaṃ nāma muttakaraṇassa dhovanā vuccati.

Ādiyamānāyāti dhovantiyā.

Dvaṅ­gula­pabba­paramaṃ ādātabbanti dvīsu aṅgulesu dve pabbaparamā ādātabbā.

Taṃ atikkāmentiyāti samphassaṃ sādiyantī antamaso kesag­gamattampi atikkāmeti, āpatti pācittiyassa.
