The Buddha uses a simile of two or three drops of water drawn out from the great ocean to illustrate the extent of suffering that is exhausted and overcome by a disciple of the noble ones who has attained right view.
Samudda sutta - Ocean
At Sāvatthi.
"Bhikkhus, suppose a person were to draw out two or three drops of water from the great ocean.
What do you think, bhikkhus, which is greater: the two or three drops of water that have been drawn out, or the water in the great ocean?"
"Venerable sir, the water in the great ocean is indeed far greater. The two or three drops of water that have been drawn out are very little. Compared to the water in the great ocean, these two or three drops do not amount to a hundredth part, nor a thousandth part, nor even a hundred-thousandth part."
"Just so, bhikkhus, for the disciple of the noble ones who has attained right view, who has completely penetrated [the four noble truths], this much greater is the suffering that is exhausted and overcome; only a small amount remains. It does not come to a hundredth part, nor to a thousandth part, nor to a hundred-thousandth part of the former mass of suffering that is exhausted and overcome compared to this final state of having at most seven more existences. Thus great, bhikkhus, is the realization of the Dhamma; thus great is the attainment of the vision of the Dhamma."
