俱舍論記 29.59

29.59

「論曰至未曾習故」者，釋初兩句。第八解脫如先〈根品〉已辨，以即是前滅盡定故。佛唯離染得，餘皆加行得。唯依欲、色二界身起，唯聖者起。餘七解脫、八勝處、十遍處，通由二得，若曾習者，由離染得；未曾習者，由加行得。

"The treatise says: [...] because of not having practiced it before": this explains the first two lines. The eighth liberation is as already analyzed earlier in the Indriya-nirdeśa, because it is none other than the cessation attainment mentioned before. The Buddha attains it solely through detachment; all others attain it through exertion. It arises only relying upon the bodies of the desire and form realms, and is generated only by noble ones. The other seven liberations, the eight bases of mastery, and the ten totalities are universally attained through two means: those who have practiced them before attain them through detachment; those who have not practiced them before attain them through exertion.
