俱舍論記 23.146

23.146

「除彼得障至謂毀臺觀」者，答。除彼涅槃得之障故。此得被他惑障不生，若斷惑障得彼涅槃。此得起故涅槃體顯，故說涅槃名為所作。又解：除彼惑得障，起得涅槃。涅槃現故，說所作言。如言作空，謂毀臺觀。空顯義邊，空名所作。涅槃亦爾。

[On the passage] from "Removing the obstacles to its acquisition" down to "meaning destroying a tower": this replies. Because of removing the obstacles to the acquisition of that nirvāṇa. This acquisition is obstructed by other defilements and does not arise; if one severs the obstacle of defilements, one acquires that nirvāṇa. Because this acquisition arises, the reality of nirvāṇa is revealed; therefore nirvāṇa is called 'that which is made'. Another explanation: removing the obstacle that is the acquisition of those defilements gives rise to the acquisition of nirvāṇa. Because nirvāṇa becomes manifest, the word 'made' is used. Just as when one speaks of 'making empty space', it refers to destroying a tower. From the perspective of empty space being revealed, empty space is called 'that which is made'. Nirvāṇa is also like this.
