拘薩羅人（Kosalans）位於阿致羅筏底河（Aciravatī）附近的一處市鎮，佛陀曾到訪，並在此回答阿難（Ānanda）關於自己如何得知提婆達多（Devadatta）不可救藥之惡行的提問，說出《知人根經》（Purisindriyañāṇa Sutta）。

A township of the Kosalans near the Aciravatī visited by the Buddha, where he taught the Purisindriyañāṇa Sutta in response to Ānanda’s question about how he knew of Devadatta’s incorrigible wickedness.
