“Seyyathāpi, bhikkhave, ayaṁ mahāpathavī ekodakā assa. Tatra puriso ekacchiggaḷaṁ yugaṁ pakkhipeyya. Tamenaṁ puratthimo vāto pacchimena saṁhareyya, pacchimo vāto puratthimena saṁhareyya, uttaro vāto dakkhiṇena saṁhareyya, dakkhiṇo vāto uttarena saṁhareyya. Tatrassa kāṇo kacchapo. So vassasatassa vassasatassa accayena sakiṁ sakiṁ ummujjeyya. Taṁ kiṁ maññatha, bhikkhave, api nu kho kāṇo kacchapo vassasatassa vassasatassa accayena sakiṁ sakiṁ ummujjanto amusmiṁ ekacchiggaḷe yuge gīvaṁ paveseyyā”ti? “Adhiccamidaṁ, bhante, yaṁ so kāṇo kacchapo vassasatassa vassasatassa accayena sakiṁ sakiṁ ummujjanto amusmiṁ ekacchiggaḷe yuge gīvaṁ paveseyyā”ti.
A Yoke With a Hole (2nd)
“Mendicants, suppose the earth was entirely covered with water. And a person threw a yoke with a single hole into it. The east wind wafts it west; the west wind wafts it east; the north wind wafts it south; and the south wind wafts it north. And there was a one-eyed turtle who popped up once every hundred years. What do you think, mendicants? Would that one-eyed turtle, popping up once every hundred years, still poke its neck through the hole in that yoke?” “It would be an anomaly, sir.”
