俱舍論記 26.79

26.79

「若爾何故至不還墮三有」者，第二師難。若言離貪嗔癡心亦通有漏，何故經言：離貪、嗔、癡心不還墮三有。既言不墮三有，明知離貪心等唯是無漏。

Regarding [the text from] “If so, why” up to “does not fall back into the three realms of existence?”: this is the second master's objection. If you say that a mind free from lust, hatred, and delusion also includes what is sāsrava, why does the sūtra say: a mind free from lust, hatred, and delusion does not fall back into the three realms of existence? Since it says it does not fall into the three realms of existence, we clearly know that minds free from lust and so on are exclusively undefiled (anāsrava).
