[317] Dwelling at Sāvatthī. … There the Blessed One … "Bhikkhus, suppose that where these great rivers meet and converge — namely, the Gaṅgā, the Yamunā, the Aciravatī, the Sarabhū, and the Mahī — that water were to become exhausted and eliminated, except for two or three drops of water. What do you think, bhikkhus: which is more — the water of the confluence that has been exhausted and eliminated, or the two or three drops of water that remain?"
"Venerable sir, the water of the confluence that has been exhausted and eliminated is more; the two or three drops of water that remain are trifling. Compared with the water of the confluence that has been exhausted and eliminated, the two or three drops of water that remain do not amount to a hundredth part, nor to a thousandth part, nor to a hundred-thousandth part."
