Idha bhikkhave, assutavā puthujjano ariyānaṃ adassāvī ariyadhammassa akovido ariyadhamme avinīto, sappurisānaṃ adassāvī sappurisadhammassa akovido sappurisadhamme avinīto rūpaṃ attato samanupassati. Yā kho pana sā, bhikkhave, samanupassanā saṅkhāro so. So pana saṅkhāro kiṃnidāno kiṃsamudayo kiṃjātiko kiṃpabhavo? Avijjāsamphassajena, bhikkhave, vedayitena phuṭṭhassa assutavato puthujjanassa uppannā taṇhā; tatojo so saṅkhāro. Iti kho, bhikkhave, sopi saṅkhāro anicco saṅkhato paṭiccasamuppanno. Sāpi taṇhā aniccā saṅkhatā paṭiccasamuppannā. Sāpi vedanā aniccā saṅkhatā paṭiccasamuppannā. Sopi phasso anicco saṅkhato paṭiccasamuppanno. Sāpi avijjā aniccā saṅkhatā paṭiccasamuppannā .
There is the case where an uninstructed, run-of-the-mill person [putthujano] — who has no regard for noble ones, is not well-versed or disciplined in their Dhamma; who has no regard for men of integrity, is not well-versed or disciplined in their Dhamma — assumes form to be the self. That assumption is a fabrication. Now what is the cause, what is the origination, what is the birth, what is the coming-into-existence of that fabrication? To an uninstructed, run-of-the-mill person [putthujano], touched by that which is felt born of contact with ignorance, craving arises. That fabrication is born of that. And that fabrication is inconstant, fabricated, dependently co-arisen. That craving... That feeling... That contact... That ignorance is inconstant, fabricated, dependently co-arisen.
