[1609] "Bhikkhus, just as, where these great rivers flow together and converge — that is to say, the Gaṅgā, the Yamunā, the Aciravatī, the Sarabhū, and the Mahī — it is not easy there to reckon the measure of the water thus: 'There are so many āḷhakas of water,' or 'so many hundreds of āḷhakas of water,' or 'so many thousands of āḷhakas of water,' or 'so many hundreds of thousands of āḷhakas of water'; rather, it is simply reckoned as an incalculable, immeasurable great mass of water — even so, bhikkhus, when a noble disciple (ariyasāvaka) is endowed with these four streams of merit (puññābhisanda), streams of the wholesome (kusalābhisanda), it is not easy to reckon the measure of his merit thus: 'So great is the stream of merit, the stream of the wholesome, the nutriment of happiness'; rather, it is simply reckoned as an incalculable, immeasurable great mass of merit." This is what the Blessed One said.
