Tatra kho bhagavā bhikkhū āmantesi – ‘‘seyyathāpi, bhikkhave, ye keci tiracchānagatā pāṇā, sīho migarājā tesaṃ aggamakkhāyati, yadidaṃ – thāmena javena sūrena [sūriyena (sī. syā. kaṃ.)]; evameva kho, bhikkhave, ye keci bodhipakkhiyā dhammā, paññindriyaṃ tesaṃ aggamakkhāyati, yadidaṃ – bodhāya’’.

‘‘Katame ca, bhikkhave, bodhipakkhiyā dhammā? Saddhindriyaṃ, bhikkhave, bodhipakkhiyo dhammo, taṃ bodhāya saṃvattati; vīriyindriyaṃ bodhipakkhiyo dhammo, taṃ bodhāya saṃvattati; satindriyaṃ bodhipakkhiyo dhammo, taṃ bodhāya saṃvattati; samādhindriyaṃ bodhipakkhiyo dhammo, taṃ bodhāya saṃvattati; paññindriyaṃ bodhipakkhiyo dhammo, taṃ bodhāya saṃvattati. Seyyathāpi, bhikkhave, ye keci tiracchānagatā pāṇā, sīho migarājā tesaṃ aggamakkhāyati, yadidaṃ – thāmena javena sūrena; evameva kho, bhikkhave, ye keci bodhipakkhiyā dhammā, paññindriyaṃ tesaṃ aggamakkhāyati, yadidaṃ – bodhāyā’’ti.
