1 Ekaṃ samayaṃ bhagavā sumbhesu viharati sedakaṃ nāma sumbhānaṃ nigamo. Tatra kho bhagavā bhikkhū āmantesi:  "bhūtapubbaṃ, bhikkhave, caṇḍālavaṃsiko caṇḍālavaṃsaṃ ussāpetvā medakathālikaṃ antevāsiṃ āmantesi:  ‘ehi tvaṃ, samma medakathālike, caṇḍālavaṃsaṃ abhiruhitvā mama uparikhandhe tiṭṭhāhī’ti. ‘Evaṃ, ācariyā’ti kho, bhikkhave, medakathālikā antevāsī caṇḍālavaṃsikassa paṭissutvā caṇḍālavaṃsaṃ abhiruhitvā ācariyassa uparikhandhe aṭṭhāsi. Atha kho, bhikkhave, caṇḍālavaṃsiko medakathālikaṃ antevāsiṃ etadavoca:  ‘tvaṃ, samma medakathālike, mamaṃ rakkha, ahaṃ taṃ rakkhissāmi. Evaṃ mayaṃ aññamaññaṃ guttā aññamaññaṃ rakkhitā sippāni ceva dassessāma, lābhañca lacchāma, sotthinā ca caṇḍālavaṃsā orohissāmā’ti. Evaṃ vutte, bhikkhave, medakathālikā antevāsī caṇḍālavaṃsikaṃ etadavoca:  ‘na kho panetaṃ, ācariya, evaṃ bhavissati. Tvaṃ, ācariya, attānaṃ rakkha, ahaṃ attānaṃ rakkhissāmi. Evaṃ mayaṃ attaguttā attarakkhitā sippāni ceva dassessāma, lābhañca lacchāma, sotthinā ca caṇḍālavaṃsā orohissāmā’"ti.

2 "So tattha ñāyo"ti bhagavā etadavoca, "yathā medakathālikā antevāsī ācariyaṃ avoca. Attānaṃ, bhikkhave, rakkhissāmīti satipaṭṭhānaṃ sevitabbaṃ; paraṃ rakkhissāmīti satipaṭṭhānaṃ sevitabbaṃ. Attānaṃ, bhikkhave, rakkhanto paraṃ rakkhati, paraṃ rakkhanto attānaṃ rakkhati.

3 Kathañca, bhikkhave, attānaṃ rakkhanto paraṃ rakkhati? Āsevanāya, bhāvanāya, bahulīkammena – evaṃ kho, bhikkhave, attānaṃ rakkhanto paraṃ rakkhati. Kathañca, bhikkhave, paraṃ rakkhanto attānaṃ rakkhati? Khantiyā, avihiṃsāya, mettacittatāya, anudayatāya – evaṃ kho, bhikkhave, paraṃ rakkhanto attānaṃ rakkhati. Attānaṃ, bhikkhave, rakkhissāmīti satipaṭṭhānaṃ sevitabbaṃ; paraṃ rakkhissāmīti satipaṭṭhānaṃ sevitabbaṃ. Attānaṃ, bhikkhave, rakkhanto paraṃ rakkhati, paraṃ rakkhanto attānaṃ rakkhatī"ti.
