又阿含經云。遠惡近善有四法。當急走避之百由旬。一由旬四十里。百由旬四千里。四法者。一惡友。二惡眾。三或多語笑。四或瞋或鬪。

Furthermore, the Āgama-sūtras state: There are four dharmas for keeping far from evil and drawing near to good; one should run quickly to avoid them by a hundred yojanas. One yojana is forty li; a hundred yojanas is four thousand li. The four dharmas are: first, bad friends; second, bad assemblies; third, much talking and laughing; fourth, anger and quarreling.
