9. It will be convenient to start at the end of the paticcasamuppāda formulation and to discuss jāti and jarāmarana first. To begin with, jāti is 'birth' and not 're-birth'. 'Re-birth' is punabbhavābhinibbatti, as in Majjhima v,3 <M.i,294> where it is said that future 'birth into renewed existence' comes of avijjā and tanhā; and it is clear that, here, two successive existences are involved. It is, no doubt, possible for a Buddha to see the re-birth that is at each moment awaiting a living individual who still has tanhā—the re-birth, that is to say, that is now awaiting the individual who now has tanhā. If this is so, then for a Buddha the dependence of re-birth upon tanhā is a matter of direct seeing, not involving time. But this is by no means always possible (if, indeed, at all) for an ariyasāvaka, who, though he sees paticcasamuppāda for himself, and with certainty (it is aparapaccayā ñānam), may still need to accept re-birth on the Buddha's authority.[c] In other words, an ariyasāvaka sees birth with direct vision (since jāti is part of the paticcasamuppāda formulation), but does not necessarily see re-birth with direct vision. It is obvious, however, that jāti does not refer straightforwardly to the ariyasāvaka's own physical birth into his present existence; for that at best could only be a memory, and it is probably not remembered at all. How, then, is jāti to be understood?
10.Upādānapaccayā bhavo; bhavapaccayā jāti; jātipaccayā jarāmaranam... With holding as condition, being; with being as condition, birth; with birth as condition, ageing-&-death...
The fundamental upādāna or 'holding' is attavāda (see Majjhima ii,1 <M.i,67>), which is holding a belief in 'self'. The puthujjana takes what appears to be his 'self' at its face value; and so long as this goes on he continues to be a 'self', at least in his own eyes (and in those of others like him). This is bhava or 'being'. The puthujjana knows that people are born and die; and since he thinks 'my self exists' so he also thinks 'my self was born' and 'my self will die'. The puthujjana sees a 'self' to whom the words birth and death apply.[d] In contrast to the puthujjana, the arahat has altogether got rid of asmimāna (not to speak of attavāda—see MAMA), and does not even think 'I am'. This is bhavanirodha, cessation of being. And since he does not think 'I am' he also does not think 'I was born' or 'I shall die'. In other words, he sees no 'self' or even 'I' for the words birth and death to apply to. This is jātinirodha and jarāmarananirodha. (See, in Kosala Samy. i,3 <S.i,71>, how the words birth and death are avoided when the arahat is spoken of.
Atthi nu kho bhante jātassa aññatra jarāmaranā ti. N'atthi kho mahārāja jātassa aññatra jarāmaranā. Ye pi te mahārāja khattiyamahāsālā... brāhmanamahāsālā... gahapatimahāsālā..., tesam pi jātānam n'atthi aññatra jarāmaranā. Ye pi te mahārāja bhikkhu arahanto khīnāsavā..., tesam pāyam kāyo bhedanadhammo nikkhepanadhammo ti.)
-- For one who is born, lord, is there anything other than ageing-&-death?—For one who is born, great king, there is nothing other than ageing-&-death. Those, great king, who are wealthy warriors... wealthy divines... wealthy householders...,—for them, too, being born, there is nothing other than ageing-&-death. Those monks, great king, who are worthy ones, destroyers of the cankers...,—for them, too, it is the nature of this body to break up, to be laid down.
The puthujjana, taking his apparent 'self' at face value, does not see that he is a victim of upādāna; he does not see that 'being a self' depends upon 'holding a belief in self' (upādānapaccayā bhavo); and he does not see that birth and death depend upon his 'being a self' (bhavapaccayā jāti, and so on). The ariyasāvaka, on the other hand, does see these things, and he sees also their cessation (even though he may not yet have fully realized it); and his seeing of these things is direct. Quite clearly, the idea of re-birth is totally irrelevant here.
