拘萨罗人（Kosalans）位于阿致罗筏底河（Aciravatī）附近的一处市镇，佛陀曾到访，并在此回答阿难（Ānanda）关于自己如何得知提婆达多（Devadatta）不可救药之恶行的提问，说出《知人根经》（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.
