經曰「佛告優婆離是名」以下，第四總結。言因緣者，為利眾生因緣故，命終後上生天也。

From the text stating, “The Buddha told Upāli, ‘This is called…’” onwards, this is the fourth [section], a general summary. Speaking of causes and conditions means: due to the causes and conditions of benefiting sentient beings, after the end of life one ascends to be born in heaven.
