Visuddhimagga XVII-20

 Avijjādisīsena niddiṭṭhapaccayesu hi ye paccayā yaṃ saṅkhārādikaṃ dhammaṃ uppādenti, na te aññamaññaṃ apaṭicca aññamaññavekalle sati uppādetuṃ samatthāti. Tasmā paṭicca samaṃ saha ca na ekekadesaṃ, nāpi pubbāparabhāvena ayaṃ paccayatā dhamme uppādetīti atthānusāravohārakusalena muninā evamidha bhāsitā, paṭiccasamuppādotveva bhāsitāti attho.

即因为那些以无明等名目而说的诸缘中的缘，生起行等的法，如果它们不互相为缘及互相缺乏之时，（诸法）是不可能生起的，故为缘。由于缘性的生起诸法，是以平等而非各各参差，是以俱时而非前后（故为起）。那随顺义理言说善巧的牟尼如是说此缘起之义。

Ñ(XVII,20): Among the conditions described under the headings of ignorance, etc., the respective conditions that make the [conditionally-arisen] states beginning with formations arise are incapable of making them arise when not mutually dependent and when deficient. Therefore this conditionality by depending (paṭicca—ger.) makes states arise (uppādeti) equally and together (samaṃ saha ca), not piecemeal and successively—so it has been termed here thus by the Sage who is skilled in phraseology that conforms to its meaning: it has been accurately termed 'dependent origination' (paṭicca samuppāda), is the meaning.
