[434] "It is possible, bhikkhus," the Blessed One said. "Suppose, bhikkhus, there were four disciples here, each with a lifespan of a hundred years, living for a hundred years, and if day after day they were each to recollect a hundred thousand aeons (kappa), there would still remain aeons not recollected by them, bhikkhus. And then those four disciples of mine, with a lifespan of a hundred years, living for a hundred years, would pass away at the end of those hundred years. So numerous, bhikkhus, are the aeons that have elapsed and gone by that it is not easy to count them thus: 'so many aeons,' or 'so many hundreds of aeons,' or 'so many thousands of aeons,' or 'so many hundreds of thousands of aeons.' For what reason? Because, bhikkhus, this saṃsāra is without discoverable beginning (anamatagga) … it is enough to be liberated."
The seventh [sutta].
