俱舍論疏 25.8

25.8

論「亦說名為至和合時故」，釋亦名不時解脫。三摩地等不待勝緣時得現前，故名不時也。煩惱盡故，名心解脫。

On the passage of the treatise from “It is also called ... up to ‘because of the time of harmony’”: this explains that it is also named “non-temporary liberation.” Because samādhi and the like are brought into presence without waiting for the time of superior conditions, it is called “non-temporary.” Because defilements are exhausted, it is called “mental liberation.”
