“Cattārome, bhikkhave, ariyavaṁsā aggaññā rattaññā vaṁsaññā porāṇā asaṅkiṇṇā asaṅkiṇṇapubbā, na saṅkīyanti na saṅkīyissanti, appaṭikuṭṭhā samaṇehi brāhmaṇehi viññūhi. Katame cattāro? Idha, bhikkhave, bhikkhu santuṭṭho hoti itarītarena cīvarena, itarītaracīvarasantuṭṭhiyā ca vaṇṇavādī, na ca cīvarahetu anesanaṁ appatirūpaṁ āpajjati, aladdhā ca cīvaraṁ na paritassati, laddhā ca cīvaraṁ agadhito amucchito anajjhosanno ādīnavadassāvī nissaraṇapañño paribhuñjati; tāya ca pana itarītaracīvarasantuṭṭhiyā nevattānukkaṁseti, no paraṁ vambheti. Yo hi tattha dakkho analaso sampajāno patissato, ayaṁ vuccati, bhikkhave, bhikkhu porāṇe aggaññe ariyavaṁse ṭhito.
The Noble Customs
“Mendicants, these four noble customs are primordial, long-standing, customary, and traditional. They are uncorrupted, as they have been since the beginning. They’re not being corrupted now, nor will they be. Sensible ascetics and brahmins don’t look down on them. What four? Firstly, a mendicant is content with any kind of robe, and praises such contentment. They don’t employ improper solicitation for the sake of a robe. They don’t worry if they don’t get a robe. And if they do get a robe, they use it untied, uninfatuated, unattached, seeing the drawback, and understanding the escape. But they don’t glorify themselves or put others down on account of their contentment. A mendicant who is deft, tireless, aware, and mindful in this is said to stand in the ancient, primordial noble custom.
