佛說五無返復經 1.10

1.10

姊即向梵志說喻言：「我等兄弟，譬如工師入山斫材縛筏水中，卒逢大風，吹破筏散隨水流去，前後分張，不相顧望。我弟亦爾，如是宿命因緣，一時共合會，在一家生。隨命長短，死亡無常，合會有離。我弟命盡，各自隨行，無常對至，隨其本行，不能相救。」

The sister immediately spoke a parable to the brahmacārin, saying, "We siblings are like craftsmen who enter the mountains to chop timber and bind a raft on the water. Suddenly encountering a great wind, the raft is broken and scattered, drifting along with the current, separated ahead and behind, unable to look out for one another. My brother is also like this: through such past causes and conditions, we temporarily gathered together and were born in one family. According to whether lifespan is long or short, death is impermanent, and what comes together must part. Now that my brother's life has ended, each follows their own actions. When the retribution of impermanence arrives, one follows one's own past actions, and we cannot save each other."
