俱舍論疏 10.151

10.151

論「非阿羅漢至故作是說」，證唯染也。既說羅漢有六恒住、無數行境，故知羅漢善喜、捨非意近行也。

[On the Śāstra's statement:] 'It is not that an arhat [up to] therefore it is said thus', this proves that they are solely defiled. Since it is said that an arhat has the six constant abidings and does not frequently range over objects, we know that an arhat's wholesome joy and equanimity are not mental investigations.
