300. Kathaṃ aparipakkato?

（六）如何「以未消化」而观察？

Ñ(XI,19): 6. How as to what is uncooked (undigested)?

So panāyamāhāro evarūpe okāse nidhānamupagato yāva aparipakko hoti, tāva tasmiññeva yathāvuttappakāre paramandhakāratimise nānākuṇapagandhavāsitapavanavicarite atiduggandhajegucche padese yathā nāma nidāghe akālameghena abhivuṭṭhamhi caṇḍālagāmadvāraāvāṭe patitāni tiṇapaṇṇakilañjakhaṇḍaahikukkuramanussakuṇapādīni sūriyātapena santattāni pheṇapupphuḷakācitāni tiṭṭhanti, evameva taṃdivasampi hiyyopi tato purime divasepi ajjhohato sabbo ekato hutvā semhapaṭalapariyonaddho kāyaggisantāpakuthitakuthanasañjātapheṇapupphuḷakācito paramajegucchabhāvaṃ upagantvā tiṭṭhatīti evaṃ aparipakkato paṭikkūlatā paccavekkhitabbā.

那吃下去的食物，贮藏在那样的地方，直至未曾消化的期间，停在前面所说的极黑暗犹如带着各种臭尸的气味的风的通路而极臭极可厌恶的处所（胃），把今天、昨天、前天所吃的一切饮食集在一起，盖着痰的膜，由身火的热力煮烧，生起了涎沫气泡，现起极其可厌的状态，正如旱热之时，由于意外的密云骤雨，把草、叶、坏席片、蛇尸、狗尸、人尸等都集中到旃陀罗村门前的池塘中，由于太阳的热力所熏，生存着许多的涎沫气泡一样。他应该这样的依未消化而观察食的可厌。

Ñ: After this nutriment has arrived at such a place for its receptacle, then for as long as it remains uncooked it stays in that same place just described, which is shrouded in absolute darkness, pervaded by draughts, tainted by various smells of ordure and utterly fetid and loathsome. And just as when a cloud out of season has rained during a drought and bits of grass and leaves and rushes and the carcases of snakes, dogs and human beings that have collected in a pit at the gate of an outcaste village remain there warmed by the sun's heat until the pit becomes covered with froth and bubbles, so too, what has been swallowed that day and yesterday and the day before remains there together, and being smothered by the layer of phlegm and covered with froth and bubbles produced by digestion through being fermented by the heat of the bodily fires, it becomes quite loathsome. This is how repulsiveness should be reviewed as to what is uncooked.
