5.99

論。九者至不樂世間　釋曰。雖未得定者。非謂未曾得也。謂說雖未常得定心。亦有出定起發心時。由前定力衰煩惱種。於諸時處不起現惑。是故名減損煩惱。故斯本言煩種薄終不現起。諸纏垢縛或不現故不樂世間。

[Treatise:] Ninth, [even if they have not yet attained concentration, in all times and places their afflictions are attenuated and] they take no delight in the world.
[Commentary:] "Even if they have not yet attained concentration" does not mean they have never attained it. It means to say that although they have not constantly attained the mind of concentration, there are also times when they emerge from concentration and give rise to the mind of aspiration. Through the power of previous concentration, the seeds of affliction are weakened, and in various times and places active afflictions do not arise; therefore it is called "attenuating afflictions". Thus that [new] text says that because the seeds of affliction are thin, they never actively arise; because the bondages of defilements do not actively manifest, they take no delight in the world.
