10. Dīghaṭṭhipañha Question on Long Bones
Rājā āha—The king asked:
“bhante nāgasena, tumhe evaṁ bhaṇatha—“Venerable Nāgasena, you say thus,
‘aṭṭhikāni dīghāni yojanasatikānipī’ti, rukkhopi tāva natthi yojanasatiko, kuto pana aṭṭhikāni dīghāni yojanasatikāni bhavissantī”ti? ‘There are long bones extending one hundred yojanas.’ Since there is no tree extending that far, how then could there be long bones extending one hundred yojanas?”
“Taṁ kiṁ maññasi, mahārāja, sutaṁ te ‘mahāsamudde pañcayojanasatikāpi macchā atthī’”ti? “What do you think, your majesty, have you heard that in the great ocean there are fish extending for five hundred yojanas?”
“Āma, bhante, sutan”ti. “Yes, venerable sir, I have heard so.”
“Nanu, mahārāja, pañcayojanasatikassa macchassa aṭṭhikāni dīghāni bhavissanti yojanasatikānipī”ti? “Is it not, your majesty, that the long bones of such a fish would extend for a hundred yojanas?”
“Kallosi, bhante nāgasenā”ti. “You are clever, venerable Nāgasena.”
