In what way does the account in Chapter 31 redefine death, transforming it into 'true self-salvation'?

The narrative in Chapter 31 fundamentally redefines death, particularly when it occurs in a saint's presence. Instead of an end, it is portrayed as a ultimate spiritual achievement. The text explicitly asks, "how can that be called death?" and answers that it is "true self-salvation" (verse 151). This transformation occurs because the soul is liberated from the cycle of rebirth; as verse 150 says, "there is no return for them." This event is framed as conquering the mortal world and attaining heavenly bliss. By leaving the body before a saint's gaze, the creature's past karmic bonds are broken, and its sins are atoned for, thus achieving the ultimate goal of salvation on its own, as highlighted in verse 154.
