Samyuktagama (Sanskrit fragments) 259.12

259.12

舍利弗言：「拘絺羅！得斯陀含果證已，欲得阿那含果證者，當復精勤思惟：『此五受陰法為病、為癰、為刺、為殺、無常、苦、空、非我。』所以者何？是所應處故。若比丘於此五受陰精勤思惟，得阿那含果證。」

Śāriputra replied, “Kauṣṭhila, someone who wants to realize the fruit of non-returning after realizing the fruit of once-returning should also diligently contemplate this, ‘The five acquired aggregates are like illnesses, abscesses, thorns, and killers. They are impermanent, painful, empty, and not self.’ Why is that? Because it’s appropriate for his situation. If a monk diligently contemplates [65c] these five acquired aggregates, he’ll realize the fruit of non-returning.”
