6.p66

“When they lived for twenty years, the people again thought, ‘As a result of cultivating a little good conduct and not hurting each other, our lifespans have lengthened to twenty years. Now, we should like to increase this little goodness. What good shall we cultivate? We’ve stopped killing beings, so let’s not steal from each other.’ After they cultivated not stealing, their lifespans lengthened to forty years.
