[251] Bhikkhus, it occurred to me: 'When what exists is there aging and death? With what as condition is there aging and death?' Then, bhikkhus, through careful attention (yoniso manasikāra), there took place in me a breakthrough by wisdom (paññā): 'When there is birth (jāti), aging and death come to be; with birth as condition, aging and death.' Then, bhikkhus, it occurred to me: 'When what exists is there birth? … is there existence (bhava)? … is there clinging (upādāna)? … is there craving (taṇhā)? … is there feeling (vedanā)? … is there contact (phassa)? … are there the six sense bases (saḷāyatana)? … is there name-and-form (nāmarūpa)? With what as condition is there name-and-form?' Then, bhikkhus, through careful attention, there took place in me a breakthrough by wisdom: 'When there is consciousness (viññāṇa), name-and-form comes to be; with consciousness as condition, name-and-form.' Then, bhikkhus, it occurred to me: 'When what exists is there consciousness? With what as condition is there consciousness?' Then, bhikkhus, through careful attention, there took place in me a breakthrough by wisdom: 'When there is name-and-form, consciousness comes to be; with name-and-form as condition, consciousness.' Then, bhikkhus, it occurred to me: 'This consciousness turns back; it does not go beyond name-and-form. It is just to this extent that one might be born, or age, or die, or pass away, or be reborn — that is: with name-and-form as condition, consciousness; with consciousness as condition, name-and-form; with name-and-form as condition, the six sense bases; with the six sense bases as condition, contact … Such is the origin of this whole mass of suffering (dukkha).' 'Origin, origin' — thus, bhikkhus, in regard to dhammas unheard before, there arose in me vision, there arose knowledge (ñāṇa), there arose wisdom, there arose true knowledge, there arose light.
