Samyutta Nikaya XIII.8
Samudda Sutta
The Ocean
Staying at Savatthi. "Suppose, monks, that the great ocean were to
go to extinction, to its total end, except for two or three drops of water.
What do you think? Which would be greater: the water in the great ocean
that had gone to extinction, to its total end, or the two or three remaining
drops of water?"
"Lord, the water in the great ocean that had gone to extinction, to
its total end, would be far greater. The two or three remaining drops of
water would be next to nothing. They wouldn't be a hundredth, a thousandth,
a one hundred-thousandth -- the two or three remaining drops of water --
when compared with the water in the great ocean that had gone to extinction,
to its total end."
"In the same way, monks, for a noble disciple who is consummate in view,
an individual who has broken through [to stream-entry], the suffering &
stress that is totally ended & extinguished is far greater. That which
remains in the state of having at most seven remaining lifetimes is next
to nothing: it's not a hundredth, a thousandth, a one hundred-thousandth,
when compared with the previous mass of suffering. That's how great the
benefit is of breaking through to the Dhamma, monks. That's how great the
benefit is of obtaining the Dhamma eye."
