俱舍論記 6.206

6.206

「由得對治至名為涅槃」者，經部答。由得能對治道，便獲永違煩惱所依身，便獲永違害後有所依身，故煩惱、後有不生義邊名得涅槃，而無實體。此即理證。「復有」下，教證無體。

Regarding "Through acquiring the antidote ... is named nirvāṇa": the Sautrāntika answers. Through acquiring the path of the antidote, one attains a basis-body that permanently opposes defilements, and one attains a basis-body that permanently opposes and harms future existence; therefore, from the standpoint of the non-arising of defilements and future existence, it is named "attaining nirvāṇa," without having a real entity. This is textual proof through reasoning. Below, from "Furthermore, there is ..." is textual proof from scriptures showing the lack of an entity.
