Bhikkhus, it is more likely that the blind turtle would put his neck in the plough share and yoke the eye to the hole to see light rather than the fool once fallen to hell would gain humanity. What is the reason? Here, there is no righteous living, good conduct, merit or a pleasant mind. Here they eat each other, the weaker one is eaten up. Bhikkhus, even if the fool regains humanity after a very long time he is born (
paccājāyati) in a low clan such as with the out castes, the hunters, with the bamboo weavers, chariot builders, rubbish collectors or in such other low family. Born into a poor family without eatables, drinks and clothing, gains them with difficulty. He too is not with pleasant appearance has a deformed body and is with many ailments, either blind, deformed, lame or paralysed, or does not gain eatables, drinks, clothes, conveyances, flowers, scents, ointments, beds, dwellings and illuminations. He misbehaves by body, speech and mind and after death goes to decrease and is born (
upapajjati) in hell.
In the same manner bhikkhus, the pleasantness and pleasure experienced by the Universal Monarch on account of the seven treasures and the four powers cannot be reckoned as a comparison, not even as a quarter, nor even as a sign for the pleasantness and pleasure experienced in heaven. Bhikkhus, if that wise one after a long lapse of time was to regain humanity he would be born (
paccājāyati) in a rich, warrior clan, brahmin clan or householder clan, or such other high clan with much wealth, riches, sovereign gold and silver, with much grains. He would be handsome and pleasant to look at. a gainer of eatables, drinks, clothes, conveyances, flowers, scents, ointments, beds, dwellings and illuminations. Conducts well in body, words and mentally after death he would be born in heaven. Bhikkhus, it is like the gambler, who at the first throw wins a great mass of wealth. It would be a more lucky throw if the wise one conducting well by body, speech and mindwould after death be born (
upapajjati) in heaven Bhikkhus, now the wise one’s sphere is completely told.’
